Description

flat display panel

technical field

The present invention relates to a flat display panel, especially to a flat display panel with enhanced edge structure design.

Background technique

Compared with traditional non-flat displays, such as cathode ray tube displays, flat panel displays have the characteristics of light weight and thin thickness, which have made flat panel displays become mainstream products in the market. According to different display technologies, flat panel displays can be roughly divided into plasma displays and liquid crystal displays. Plasma displays are mainly used in large-sized thin TVs, while liquid crystal displays are used in various display devices. For example, in terms of current electronic products, almost all of them use liquid crystal display panels from large-sized thin TVs, personal computer monitors, and even small displays installed in mobile phones, digital cameras and portable music players.

Please refer to Figure 1 to Figure 3. 1 to 3 are schematic diagrams of conventional liquid crystal display panels, wherein FIG. 1 is a schematic appearance, FIG. 2 is a top view, and FIG. 3 is a side view. As shown in FIGS. 1 to 3 , the conventional liquid crystal display panel 10 mainly includes a first substrate (array substrate) 12, a second substrate (color filter substrate) 14 stacked on the first substrate 12, and Liquid crystal molecules (not shown) are disposed between the first substrate 12 and the second substrate 14 . In addition, an upper polarizer 16 and a lower polarizer 18 are respectively disposed on the upper surface of the first substrate 12 and the lower surface of the second substrate 14 .

Generally speaking, the size of the first substrate 12 is larger than the size of the second substrate 14, wherein the overlapping area of the first substrate 12 and the second substrate 14 is the display area 20 for displaying images, and the first substrate 12 is not covered. The area covered by the second substrate 14 is the peripheral area 22 for connecting with external circuits. As shown in FIGS. 1 to 3 , the material of the first substrate 12 is glass, and the peripheral region 22 is not covered by the second substrate 14, so the structural strength of the peripheral region 22 is stronger than that of the display region 20 covered by the second substrate 14. Fragile. In this situation, the peripheral area 22 is likely to be cracked, especially at the two corners of the peripheral area 22 . For example, during the encapsulation process of the driver IC, or during the drop test for small-sized panels, the peripheral region 22 of the first substrate 12 often cracks due to poor structural strength.

Detailed ways

Please refer to Figure 4 to Figure 6. 4 to 6 are schematic views of a preferred embodiment of the flat display panel of the present invention, wherein FIG. 4 is a schematic appearance, FIG. 5 is a top view, and FIG. 6 is a side view. It is worth noting that the structural design of the flat display panel of the present invention is not limited to a specific display panel, but can be applied to various flat display panels such as liquid crystal display panels, organic electroluminescent display panels, or plasma display panels. As shown in FIGS. 4 to 6 , the flat display panel 50 of this embodiment includes a first substrate 52 and a second substrate 54 attached on the first substrate 52 . The first substrate 52 is the lower substrate of the flat display panel 50 and may also be called an array substrate or a TFT substrate. The second substrate 54 is an upper substrate. If the flat panel display is a liquid crystal display panel, the upper substrate is also called a color filter substrate. In addition, the first substrate 52 and the second substrate 54 are made of glass or quartz.

The first substrate 52 includes a display area 56 for displaying images, and a peripheral area 58 located on at least one side of the first substrate 52 . The peripheral region 58 includes a driver IC connection region 60, and two corner regions 62, wherein a driver IC 64 is arranged on the driver IC connection region 60, and a flexible printed circuit board 66 (not shown in FIG. not shown) electrical connections.

It is worth noting that since the driver IC 64 and the flexible printed circuit board 66 are arranged on the driver IC connection area 60 of the first substrate 52, the corner region 62 of the first substrate 52 does not have the function of external connection, so it covers the The extension area 70 of the second substrate 54 on the corner area 62 has the function of strengthening the structure and does not affect the package of the flat display panel 50 .

As shown in Figures 4 to 6, each extension area 70 in this embodiment is a rectangular protrusion, one side of which is connected to the main body area 68, and the two sides of the rectangular protrusion are roughly aligned with the edges of the corresponding corner area 62 , and one side of the rectangular protrusion and one side of the main body region 68 approximately form a right angle. In this embodiment, the edges of the rectangular protrusions are roughly aligned with the edges of the corresponding corner regions 62 , but the present invention is not limited thereto, and the edges of the rectangular protrusions may not be aligned with the edges of the corner regions 62 as required.

The embodiment of FIG. 8 is different from the previous embodiments in that the flat display panel has a fillet design. As shown in FIG. 8 , the extension region 92 of the flat panel display panel 90 in this embodiment is a rectangular protrusion, but one side thereof forms a rounded corner with one side of the main body region 94 .

As shown in the embodiment of FIG. 9 , the extension region 102 of the flat display panel 100 surrounds the driver IC 104 and does not cover the driver IC 104 .

As shown in the embodiment of FIG. 10 , the two extension regions 112 of the flat display panel 110 are respectively trapezoidal protrusions protruding from the main body region 114 .
