More specifically, in the display of the following embodiment, a pattern of continuous scrolling can be displayed. In addition, when the display displays a continuous scrolling pattern, a three-dimensional (three-dimensional) visual effect of depth or front and back can be presented, and when the display does not display a continuous scrolling pattern, a flat (two-dimensional) display effect can be exhibited. However, the invention is not limited to such applications. Any need to display a three-dimensional image effect in the display, such as the depth or the front and back, and the timely switching from the stereoscopic image effect to the two-dimensional image display are all applicable to the display of the present invention.

Please refer to FIG. 1 and FIG. 2 together. FIG. 1 is an exploded view of the display according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the first drawing in the XZ plane. As shown in FIG. 1 , the display 10 can include a display panel 100 , a backlight module 120 , and a roller 150 . The backlight module 120 can include three transparent regions 121 and a light exit region 123 , and each of the transparent regions 121 can be in the direction Y. The upper rows are arranged in a row, and the light exiting area 123 can surround the light Area 121 is set. In other embodiments, there may be only one elongated light-transmissive region, and the elongated light-transmitting region occupies a position corresponding to the position occupied by the three light-transmitting regions 121 of the present embodiment. That is, the elongated light-transmissive region can be formed by the three light-transmitting regions 121 of the present embodiment. In an embodiment, the roller 150 may have a plurality of patterns 151 thereon, and the roller 150 is disposed opposite to the light transmitting region 121. In this way, when the roller 150 rotates, the portion of the display panel 100 corresponding to the light-transmitting region 121 can be seen through the light-transmitting region 121 and the pattern 151 continuously scrolled on the roller 150 is presented in front of the user.

In an embodiment, the light transmissive region 121 can be substantially an opening. In other words, the light-transmitting region 121 can be a passage through the front and rear surfaces of the backlight module 120 on the backlight module 120, and any directional light can travel in the channel without being blocked. That is, when the roller 150 is rotated, the pattern 151 that is rotating on the roller 150 can be presented to the user via the light transmitting region 121.

In some embodiments, the light-transmitting region 121 is substantially an area on the backlight module 120 that does not have light guiding capability. In detail, in the first embodiment, the backlight module 120 can be a side-lit backlight module 120, which can include a first light source module 122, and the first light source module 122 includes two light sources. The groups 122a, 122b and the light guide plate 124, the two light source groups 122a, 122b are respectively located on the two side walls of the light guide plate 124 in the Z direction, and emit light toward the light guide plate 124. The light source groups 122a and 122b are, for example, fluorescent tubes or a plurality of light emitting diodes arranged in the Y direction. The first light source module 122 is configured to provide the backlight B to the display panel 100, that is, the light emitted by the light source groups 122a, 122b. The line can be converted into planar light (backlight B) via the light guide plate 124 and emitted to the display panel 100 by the light exiting region 123. The light-transmitting region 121 on the light guide plate 124 may not have a microstructure or a mesh point for destroying the total reflection of the light. Therefore, the light-transmitting region 121 may convert the light emitted by the light source groups 122a and 122b into a planar light emission to the display instead of the light-emitting region 123. Panel 100. In other words, the light guide plate 124 of the light-transmitting region 121 can be flat, and has no ability to deflect the light emitted by the light source groups 122a and 122b in the direction of the display panel 100, but the light travels within the range of the light-transmitting region 121. It will not be blocked. That is, when the roller 150 is rotated, the image of the roller 150 can still be seen through the light-transmitting region 121 and the portion of the display panel 100 corresponding to the light-transmitting region 121, so that the pattern 151 continuously rolling on the roller 150 is presented in front of the user. In addition, it should be noted that the number of the light source groups 122a, 122b is merely an example here, and can be adjusted as needed.

Please refer to FIG. 1 . It should be noted that, in addition to the first light source module 122 , the backlight module 120 can stack one or more optical films on the light guide plate 124 according to actual use requirements ( FIG. 1 is simplified The optical film is not shown in the drawings. The optical film may include a reflective sheet, a diffusion sheet, or at least one brightness enhancing film, and the like, and the position of the optical film corresponding to the light-transmitting region 121 may be similarly hollowed out (ie, formed into an opening) or positioned for the light-transmitting region 121. A flat, light-transmissive structure that simply passes light can be formed, which can be adjusted according to actual needs.

Referring to FIG. 1 and FIG. 2 , the display 10 further includes a second light source module 130 , a first mast 140 , and a second mast 160 . The second light source module 130 and the first mast 140 can be used in this embodiment. And the configuration of the second mast 160, so that when the roller 150 is rolled, the display 10 can exhibit the image effect of the three-dimensional rotation of the scroll wheel 150. When the image of the scroll wheel 150 is not required to be presented, the display 10 is caused to present a two-dimensional image of a general flat display, and the user is not perceived by the user when the image of the display panel 100 of the display 10 is opposite to the corresponding scroll wheel 150. There are obvious shadows or dark bands at the location. In order to achieve the above object, the positional relationship of the respective members in the display 10 will be described in detail below.

As shown in FIG. 1 and FIG. 2 , the backlight module 120 can be located between the display panel 100 and the second light source module 130 , and the backlight module 120 can be located between the display panel 100 and the first mast 140 . The second light source module 130 can be located between the roller 150 and the backlight module 120. The first mast 140 can be located between the backlight module 120 and the roller 150. The second mast 160 can be located at the first mast 140. And between the rollers 150. More specifically, the display panel 100, the backlight module 120, the first mast 140, the second mast 160, and the roller 150 are sequentially disposed inside the display 10 along the direction X (horizontal direction). Further, at the rear end of the backlight module 120 along the direction Z (vertical direction), the second light source module 130, the first mast 140, and the second mast 160 are sequentially disposed.

In more detail, the second light source module 130 may include a first surface light source portion 131 and a second surface light source portion 132 , wherein the first surface light source portion 131 is located between the backlight module 120 and the second surface light source portion 132 . In some embodiments, the first surface light source portion 131 and the second surface light source portion 132 may be substantially in the same plane. The first mast 140 has a first slope 141, and the orthographic projection of the first slope 141 at the second light source module 130 is at least partially or entirely on the first side The light source portion 131 is at least partially overlapped with the light-transmitting region 121 by the front projection of the first inclined surface 141 in the backlight module 120. The orthographic projection of the roller 150 at the second light source module 130 is at least partially located on the second surface light source portion 132, and the orthographic projection of the roller 150 at the backlight module 120 at least partially overlaps the light transmitting region 121.

The first surface light source portion 131 is for providing the first planar light L1, and the second surface light source portion 132 is for providing the second planar light L2. When the display 10 does not need to present an image of the roller 150, the first surface light source portion 131 emits the first planar light L1 toward the first inclined surface 141, and the second surface light source portion 132 does not emit the second planar light L2, wherein the first inclined surface The 141 may be configured to reflect the first planar light L1 such that the first planar light L1 passes through the light transmitting region 121 to the display panel 100. At the same time, the first light source module 122 of the backlight module 120 also provides the backlight B to the display panel 100. As a result, the display panel 100 receives the forward light source corresponding to the light-transmitting area 121 and the light-emitting area 123 of the backlight module 120, so that the display panel 100 can display an image with uniform brightness. That is, the display panel 100 does not appear dark or shaded at a position corresponding to the light-transmitting region 121, thereby achieving the effect of presenting a two-dimensional picture of a general flat display.

In an embodiment, the second mast 160 is spaced apart from the first ramp 141 of the first mast 140 by a gap G. The first mast 140 is a light-transmissive cylinder and has a refractive index greater than 1, such that the first planar light L1 enters the gap G from the first mast 140, and the incident angle of the first planar light L1 at the first slope 141 When θ1 is greater than the critical angle, total reflection may occur at the first slope 141, and the first slope 141 may reflect the first planar light L1 toward the light-transmitting region 121. The first planar light L1 is passed through the light transmitting region 121 to the display panel 100.

From the perspective of FIG. 2, the first mast 140 may have a first side surface 142 and a second side surface 143 respectively connected to the first slope surface 141, wherein the first side surface 142 faces the first surface light source portion 131, and the second The side surface 143 faces the light transmitting region 121. The first planar light L1 is incident on the first side surface 142 and enters the first mast 140, and is totally reflected on the first slope 141 and is emitted from the second side surface 143 and passes through the transparent region 121 to reach the display. Panel 100. In still another embodiment, the cross section of the first mast 140 in the XZ plane may be a right triangle, and the base angle θ2 of the right triangle may range between 30 degrees and 60 degrees. In addition, in a preferred embodiment, the cross section of the first mast 140 in the XZ plane may be an isosceles right triangle, and the bottom angle θ2 may be approximately 45 degrees, and the incident angle θ1 may be approximately The base angle θ2 is equal.

Then, when the display 10 needs to present an image of the rotation of the scroll wheel 150, in order to create a stereoscopic effect of the scroll wheel 150 and the display panel 100, the first surface light source portion 131 no longer provides the first planar light L1. The second surface light source portion 132 emits the second planar light L2 toward the roller 150. In this way, after the second planar light L2 is irradiated to the roller 150, the image of the roller 150 can be presented to the user through the second mast 160, the first mast 140, and the display panel 100. At the same time, the first light source module 122 of the backlight module 120 also provides the backlight B to the display panel 100, so that the image displayed by the display panel 100 and the image of the roller 150 have a shallow or front-end stereo effect.

From the perspective of FIG. 2, the second mast 160 may include a third The side surface 163, the fourth side surface 164 and the second slope surface 162, wherein the third side surface 163 and the fourth side surface 164 are respectively connected to the second slope surface 162, and the fourth side surface 164 faces the roller 150, and the third side surface 163 is connected to the fourth side surface. 164 and the second slope 162, the second slope 162 may be disposed facing the first slope 141 and spaced apart from each other by a gap G. After the second planar light L2 is irradiated to the roller 150, the light reflected by the roller 150 can enter the fourth side 164 and enter the second mast 160, and pass through the second inclined surface 162, the first mast 140, and The light area 121 and the display panel 100 are presented in front of the user. In this way, by the arrangement of the second mast 160, the image of the roller 150 is substantially equal to the optical effective distance of the second mast 160 via the first mast 140, and no aberration is generated.

As can be seen from the above embodiment, the display 10 can open the first surface light source portion 131 and the second surface light source portion 132 of the second light source module 130, respectively, and the first mast 140 and the second mast 160 The configuration, while selectively creating 3D and 2D image effects. It should be noted that, in this embodiment, it is not necessary to additionally set other switching structures, such as Polymer-Dispersed Liquid Crystals (PDLC), in order to block the image of the roller 150 in the two-dimensional display mode. Therefore, the display 10 of the present embodiment has the advantage of low cost. In addition, the display 10 of the present embodiment can be manufactured by the display panel 100 in a flat display manner, which has a simple process and a high yield.

Next, the technique of illuminating the first surface light source unit 131 and the second surface light source unit 132 in a partition will be further described, as will be described below.

In a specific application, the light source of the first light source group 131b and the second light source group 132b may be a light emitting diode, but is not limited thereto. In addition, it should be noted that the light source of the first light source group 131b and the light source of the second light source group 132b may be disposed on two circuit boards, or may be disposed on the same circuit board and spaced apart by a distance S according to actual needs. In this manner, when the first light source group 131b and the second light source group 132b are respectively turned on, the first light guiding unit 131a and the second light guiding unit 132a can respectively conduct the first light source group 131b and the second light source group 132b.

The block R is connected to the second light guiding unit 132a. That is, the spacer block R is located between the first light guiding unit 131a and the second light guiding unit 132a. Further, in a variant embodiment, the spacing S also faces the spacer block R. By the configuration of the spacer block R, the light of the first light source group 131b can be prevented from being conducted to the second light guiding unit 132a, or the light of the second light source group 132b can be conducted to the first light guiding unit 131a.

In a particular application, the sheet material within the range of the spacer block R may be flat and have no microstructures or dots that reflect or deflect light. In contrast, the first light guiding unit 131a and the second light guiding unit 132a may have microstructures or dots that reflect or deflect light, so that the light of the first light source group 131b and the second light source group 132b may pass through the first The light guiding unit 131a and the second light guiding unit 132a are converted into a first planar light L1 and a second planar light L2.

Referring to FIG. 3, in order to separately control the first light source group 131b and the second light source group 132b to be respectively turned on, the display 10 may further include the control unit 170. The control unit 170 can be directly or indirectly electrically connected to the first light source group 131b and the second light source group 132b. The control unit 170 can be a logic circuit or a Complex Programmable Logic Device (CPLD), but is not limited thereto.

The control unit 170 may set the first surface light source unit 131 to be turned on and the second surface light source unit 132 to be turned off in the first display mode, and turn on the second surface light source unit 132 and turn off the first surface light source unit 131 in the second display mode. In addition, the first light source module 122 of the backlight module 120 can provide the backlight B to the display panel 100 in both the first display mode and the second display mode (please refer to FIG. 2 together). Specifically, the first display mode may be the two-dimensional (flat) display mode of the foregoing embodiment, and the display of the slot machine may be used as a display screen of the integral list or a display animation when winning the prize; The two display modes may be the three-dimensional (stereoscopic) display mode of the foregoing embodiment, such as the rotation of the slot machine. In this way, the effect of the two-dimensional or three-dimensional display mode of the foregoing embodiment can be achieved by selectively turning on the first surface light source unit 131 and turning off the second surface light source unit 132 by the control unit 170.

It should be noted that, in addition to the first surface light source portion 131 and the second surface light source portion 132, the second light source module 130 may overlap one or more optical films on at least a portion of the first light guiding unit 131a, The second light guiding unit 132a and the spacer block R are above or below the optical film, and the optical film may include a reflective sheet, a diffusion sheet, and at least one brightness enhancing film.

For example, the optical film 133 of the second light source module 130 may be, but not limited to, a reflective sheet 133a, a diffusion sheet 133b, and brightness enhancing films 133c, 133d, and the like. Moreover, the function of the functional film layer on the optical film 133 may vary depending on the type of the optical film 133. For example, the functional film layer 133e of the brightness enhancing film 133c may have the first light guiding unit 131a and the second light guiding unit. The function of the brightness of the plane light emitted by the light unit 132a.

It is worth mentioning that, in an embodiment, the functional film layer of the optical film 133 can be at least partially superposed on the first light guiding unit 131a, the second light guiding unit 132a and the spacer block R.
