Detailed ways

The core of the invention is to provide a liquid crystal display module. In the prior art, due to the limitation of the working principle of the liquid crystal display module, it usually needs to set a backlight panel capable of emitting light to generate light. For the current liquid crystal display module with its own backlight, usually the backlight can emit light of about 1200cd/m ² , but the brightness of the light passing through the liquid crystal display module is only 500cd/m ² to 600cd/m ² , which means that about 50% of the light is not effectively used, so at this stage it appears that the overall power consumption of the liquid crystal display module is relatively high.

Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to FIG. 1 , which is a schematic structural diagram of a liquid crystal display module provided by an embodiment of the present invention.

Referring to FIG. 1 , in an embodiment of the present invention, the liquid crystal display module includes a first transparent substrate 10 , a liquid crystal working layer 40 , a second transparent substrate 20 and a backlight layer 30 arranged sequentially from top to bottom; wherein, the A first polarizer 11 is pasted on the upper surface of the first transparent substrate 10 , and a second polarizer is disposed between the second transparent substrate 20 and the backlight layer 30 .

Since the product provided by the embodiment of the present invention is a liquid crystal display module, the substrate used for setting various electrodes or working components needs to ensure good light transmittance, so the above-mentioned first transparent substrate 10 and second transparent substrate 20 need to ensure Good light transmission, usually the first transparent substrate 10 and the second transparent substrate 20 are made of glass. Certainly, the specific materials and specific dimensions of the first transparent substrate 10 and the second transparent substrate 20 are not specifically limited in this embodiment of the present invention.

The above-mentioned backlight layer 30 can use an incandescent bulb, an electro-optical panel, a light-emitting diode, or a cold cathode tube as a light source to generate uniform light upward on the surface of the backlight layer 30 . Among them, the electro-optical panel can directly provide uniform light on the entire surface of the backlight layer 30 , while other light sources need to cooperate with a diffuser to provide uniform light.

The backlight layer 30 can provide light of any color, such as yellow light, green light, blue light, white light and so on. In the embodiment of the present invention, there is no specific limitation on the color of the light generated by the backlight layer 30 . Normally, when the entire liquid crystal display module displays color images, the backlight layer 30 needs to emit white light, because the white light contains the most colors of light.

Certainly, for specific parameters such as the thickness of the backlight layer 30 , reference may be made to the prior art, and details are not repeated here.

The liquid crystal display module provided by the embodiment of the present invention generally includes a first transparent substrate 10 , a liquid crystal working layer 40 , a second transparent substrate 20 and a backlight layer 30 from top to bottom. Usually, a first polarizer 11 is disposed on the upper surface of the first transparent substrate 10 , and a second polarizer 21 is disposed between the second transparent substrate 20 and the backlight layer 30 . The function of the polarizer is to only allow the light of a predetermined vibration direction to pass through. Usually, the first polarizer 11 and the second polarizer 21 arranged in the same liquid crystal display module allow the vibration directions of the light to pass through to be perpendicular to each other.

Since the liquid crystal 41 has the easy flowability of a liquid, and the liquid crystal molecules have anisotropy and orderly arrangement among the liquid crystal molecules, that is, the molecules of the liquid crystal 41 have directionality. Under the action of different electric fields, the liquid crystal molecules will be regularly rotated and arranged by 90 degrees. When used in displays and display modules, the liquid crystal 41 can produce differences in light transmittance under the action of an electric field, thereby producing light spots with different brightness on the surface of the liquid crystal display module, and then forming images.

Specifically, the liquid crystal working layer 40 can control the alignment direction of liquid crystal molecules by controlling the voltage or current across the liquid crystal 41 in the liquid crystal working layer 40 . Since polarizers are provided above and below the liquid crystal working layer 40, the difference in light transmittance can be produced by controlling the twisting direction of the liquid crystal molecules, and then the light generated by the backlight layer 30 can be controlled to correspond to each pixel after passing through the liquid crystal working layer 40. The intensity of the light can produce light and dark changes, and then generate images on the surface of the liquid crystal display module. Details about the liquid crystal working layer 40 will be introduced in detail in the following embodiments of the invention, and will not be repeated here.

In the embodiment of the present invention, a photoelectric conversion module 50 is provided in the non-display area on the lower surface of the first transparent substrate 10, and the photoelectric conversion module 50 is connected to the same conductive circuit layer 61 as the working layer.

The reverse charging of the conversion module 50 means that the current in the rechargeable battery may flow into the photoelectric conversion module 50 and cause damage to the photoelectric conversion module 50 . Therefore, in the embodiment of the present invention, it is usually necessary to add a protection circuit to the photoelectric conversion module 50 to prevent the rechargeable battery from reversely charging the photoelectric conversion module 50 .

Since the silver paste has good electrical conductivity, the above-mentioned conductive material 63 connecting the conductive circuit layer 61 and the photoelectric conversion module 50 is preferably silver paste. Of course, the conductive material 63 can also be other materials, such as solder paste, etc., and the specific material of the conductive material 63 is not specifically limited in the embodiment of the present invention.

In order to improve the conversion efficiency of the photoelectric conversion module 50 as much as possible, the way of doping ions in the N-type doped layer 52 and the P-type doped layer 51 can be heavily doped, that is, the N-type doped layer 52 can be The N-type heavily doped layer, the P-type doped layer 51 may be a P-type heavily doped layer. The ion species and doping concentration of doping in the N-type doped layer 52 and the P-type doped layer 51 are not specifically limited in the embodiment of the present invention, as long as the concentration of free electrons in the N-type doped layer 52 can be high The concentration of holes and the concentration of holes in the P-type doped layer 51 can be greater than the concentration of free electrons.

The material of the above-mentioned N-type doped layer 52 and P-type doped layer 51 can be monocrystalline silicon, polycrystalline silicon, amorphous silicon, GaAs (gallium arsenide), GaAlAs (gallium aluminum arsenide), InP (indium phosphide), CdS (cadmium sulfide), CdTe (cadmium telluride), etc., of course, the N-type doped layer 52 and the P-type doped layer 51 can also be made of other materials. The material used for the layer 51 is not specifically limited in this embodiment of the present invention.

Further, in the embodiment of the present invention, the first gate line 53 may include multiple sections of sub-gate lines distributed along a straight line, and adjacent sub-gate lines are electrically connected by electrical connection lines. That is, in the embodiment of the invention, the first grid line 53 may be a split structure, which is equivalent to that the first grid line 53 is composed of a plurality of sub-gate lines distributed along a straight line, and adjacent sub-gate lines are connected to each other through electrical connection wires. electrical connection. Since the width of the first gate line 53 is relatively wide, it will occupy a large area of the surface of the photoelectric conversion module 50 for receiving light, thereby reducing the current generated by the photoelectric conversion module 50 . Setting the first grid lines 53 on the surface of the photoelectric conversion module 50 facing the backlight layer 30 into a split structure can greatly reduce the area required by the first grid lines 53, thereby increasing the ability of the photoelectric conversion module 50 to receive the backlight layer 30. The area for emitting light, that is, increasing the area of the working area of the photoelectric conversion module 50 can further improve the conversion efficiency of the photoelectric conversion module 50 . It should be noted that, in the embodiment of the present invention, the width of the electrical connection lines connecting adjacent sub-gate lines needs to be smaller than the width of the sub-gate lines.

Of course, similar to the split structure of the first grid line 53, the second grid line 54 can also be designed as a split structure, that is, the second grid line 54 can also include a plurality of sub-grid lines, and the plurality of sub-grid lines Distributed along a straight line, the adjacent sub-gate lines are electrically connected through electrical connection lines.

Because of the outstanding conductivity of silver paste, the above-mentioned first grid lines 53 , second grid lines 54 , sub-grid lines, and electrical connection lines are usually made of silver paste at this stage. Certainly, the above-mentioned gate lines may also be made of other materials. In the embodiment of the present invention, the materials of the first gate lines 53 , the second gate lines 54 , the sub-gate lines and the electrical connection lines are not specifically limited.

Further, a light shielding layer 66 may be provided on the lower surface of the photoelectric conversion module 50 . The light-shielding layer 66 is used to block the light generated by the backlight layer 30 corresponding to the non-display area, so as to avoid the interference caused by this part of the light to the image formed on the surface of the liquid crystal display module. Since the photoelectric conversion module 50 is usually made of semiconductor material, it is not easy to cut, the photoelectric conversion module 50 may not completely cover the non-display area of the entire liquid crystal display module during the manufacturing process. That is, if only the photoelectric conversion module 50 is provided, the light generated by part of the backlight layer 30 may also irradiate the surface of the liquid crystal display module from the non-shielded non-display area, thereby affecting the image formed on the surface of the liquid crystal display module. cause disturbance. In order to avoid the occurrence of the above situation, in the embodiment of the present invention, a shielding layer can be provided on the lower surface of the photoelectric conversion module 50 to prevent the light in the non-display area from interfering with the image formed on the surface of the liquid crystal display module. Normally, the light shielding layer 66 is black.

The embodiment of the present invention specifically introduces the specific structure of the liquid crystal working layer 40. At the same time, in the liquid crystal display module provided by the embodiment of the present invention, the first gate line 53 is arranged in a split structure, which is beneficial to reduce the required area, thereby increasing the area that can receive light from the backlight layer 30 in the photoelectric conversion module 50, and then can improve the conversion efficiency of the photoelectric conversion module 50; Prevent the light in the non-display area from interfering with the image formed on the surface of the liquid crystal display module.
