Most of the existing projector technologies employ liquid crystal display (Liquid Crystal Display, LCD) or liquid crystal on silicon (Liquid Crystal on Silicon, LCOS) chips. The LCD is constructed by placing a liquid crystal cell between two parallel glass substrates. LCOS is also known as one of LCDs, and unlike conventional LCDs, one of the glass substrates is replaced with a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) substrate coated with liquid crystal silicon, thus having good electron mobility, using reflective projection, and higher light utilization efficiency.

The two substrates corresponding to each other of the LCD are a first substrate and a second substrate, wherein the first substrate is provided with a Color Filter, which is generally defined as a Color Filter (CF). The second Substrate is provided with thin film transistors (Thin Film Transistor, TFT), generally defined as an Array Substrate (Array Substrate). The color film substrate comprises a first substrate glass substrate. The frame glue structure is also called a black matrix and covers the first substrate glass substrate, and the frame glue structures are arranged at intervals to form a plurality of display areas. Each display area is provided with a single pixel unit in one-to-one correspondence, and the pixel units are optical filters with different colors. The array substrate comprises a second substrate glass substrate, and one surface of the second substrate glass substrate facing the color film substrate is provided with a plurality of Thin Film Transistors (TFTs) and metal wires for separating the thin film transistors. The display areas are arranged corresponding to the thin film transistors, and the frame structures are arranged corresponding to the metal wires. The frame glue structure can improve the contrast of liquid crystal display, prevent the mutual color mixing among the sub-pixels with different colors and enhance the contrast; meanwhile, the circuit is covered in the frame glue structure, so that the functions of covering and protecting the circuit can be achieved. Each liquid crystal pixel point on the LCD is driven by a TFT behind the pixel point, and the rotation direction of liquid crystal molecules is controlled by changing signals and voltages on the TFT, so that whether polarized light of each pixel point exits or not is controlled, and the display purpose is achieved.

Referring to fig. 1 and 2, fig. 1 is a schematic diagram of a liquid crystal display panel according to the prior art. As shown in fig. 1, the liquid crystal display panel 20 includes an array substrate 200, a color film substrate 300, and a liquid crystal layer 400. The array substrate 200 is disposed opposite to the color film substrate 300. The liquid crystal layer 400 is located between the array substrate 200 and the color film substrate 300. Fig. 2 is a top view of the frame glue structure of fig. 1, as shown in fig. 2. The color film substrate 300 includes a plurality of display regions 301 and a frame adhesive structure 302 for separating the display regions 301. The incident light 101 passes through the liquid crystal 400 and then exits from the display area 301, and the display areas 301 spaced by adjacent frame glue structures 302 are single pixel units 301a, so that all the pixel units 301a form a pattern together under the irradiation of the incident light 101. As shown in fig. 1, incident light 101 uniformly irradiates on the array substrate 200, and light passes through the liquid crystal 400 to uniformly irradiate on the display area 301 and the frame glue structure 302, and the display area 301 forms uniform emergent light 102. Because the laser power is high in laser projection, light is strong, the frame gum structure 302 volatilizes when encountering strong light, and volatilized ion impurities pollute the liquid crystal system to lead to the display panel 20 to be stained, and meanwhile, the circuit in the frame gum structure 302 is damaged and loses protection, so that the whole liquid crystal module is finally disabled.

Therefore, in order to prevent the frame glue structure 302 from being damaged by light irradiation, the light irradiated to the frame glue structure 302 is usually shielded, but the shielding of the light causes a great amount of light loss, and the loss of the incident light 101 causes problems such as pixel defects, unclear images, and low display efficiency.

Referring to fig. 3, fig. 3 is a schematic diagram of a liquid crystal display panel according to the related art. As shown in fig. 3, the liquid crystal display panel 20 adds a first microlens structure 500 at the array substrate 200 on the basis of the technology of fig. 1. The bottom plane of the microlens is disposed away from the incident light 101, and the cambered surface is disposed toward the incident light 101. Each pixel unit 301a is correspondingly provided with a micro lens, and a plurality of micro lenses are connected end to form a first micro lens structure 500. When the incident light 101 uniformly irradiates the first microlens structure 500, the first microlens structure 500 converges the incident light 101, so that not only the light originally irradiated on the frame glue structure 302 changes the light path, but also the light irradiated on the display area 301 is converged, so that the light in each pixel unit 301a is concentrated on a point in the unit and then emitted from the point. Converging the line of incident light 101 through the first microlens structure 500 will result in an uneven distribution of the system exit light 102; this solution increases the etendue of the system and causes irreversible losses to the optical system with respect to the prior art. Meanwhile, since each pixel unit 301a requires a corresponding microlens, the cost of production and manufacture will be greatly increased. As the demand for high definition display increases, the cost of applying the first microlens structure 500 will be higher and higher.

In order to correct the problem of uneven light distribution caused by the technique shown in fig. 3, referring to fig. 4, fig. 4 is a schematic diagram of a liquid crystal display panel according to another related art. As shown in fig. 4, the liquid crystal display panel 20 is based on the technology of fig. 3, and a second microlens structure 502 is added at the light emitting position of the pixel unit 301 a. The second microlens bottom plane is disposed close to the display region 301, and the cambered surface is disposed away from the display region 301. A second microlens is also disposed in each pixel unit 301a, and a plurality of second microlenses are connected end to form a second microlens structure 502. When the incident light 101 uniformly irradiates on the first microlens structure 501, the first microlens structure 501 converges the incident light 101, so that the light in the pixel unit 301a is concentrated at a point in the unit, and the converged emergent light 102 is collimated by the second microlens structure 502. The problem of non-uniform distribution of the outgoing light 102 is improved compared to the technique of fig. 3, but the non-uniform distribution of the outgoing light 102 of the system is still present compared to the prior art and is not well resolved. In addition, the etendue continues to increase, still causing irreversible loss to the optical system. Meanwhile, with respect to the technique of fig. 3, since each pixel unit 301a needs to be provided with two microlenses, the manufacturing cost is further increased.

Therefore, in order to solve the above-mentioned problems, please refer to fig. 5, which is a first embodiment of the liquid crystal display panel according to the present application. Fig. 5 omits the technology of disposing the microlens structure, but a light modulation layer 600 is disposed on the surface of the array substrate 200 facing the color film substrate 300, the light modulation layer 600 includes a light modulation portion 601 and a light transmission portion 602, the light modulation portion 601 is disposed corresponding to the frame glue structure 302, and the light transmission portion 602 is disposed corresponding to the display area 301. In the direction of the array substrate 200 facing the color film substrate 300, the light-transmitting portion 602 does not change the light path of the incident light 101, so that all the light rays emitted from the incident light 101 through the light-transmitting portion 602 are emitted after being irradiated to the display area 301. The light adjusting portion 601 is used for changing the outgoing angle of the light beam directly irradiating the frame glue structure 302, so that the light beam irradiated to the frame glue structure 302 is greatly reduced.

The light modulation portion 601 is a groove disposed on the light modulation layer 600. The opening of the groove faces away from the color film substrate 300. The dimming layer 600 is connected to each other toward the sidewalls of the recess. In this embodiment, the sidewall of the dimming layer 600 facing the groove is a plane.

When the incident light 101 is uniformly irradiated on the light modulation layer 600, and the incident light 101 is irradiated on the light transmission portion 602, the incident light 101 passes through the liquid crystal 400 through the light transmission portion 602, is vertically irradiated on the display area 301, and is uniformly emitted; when the incident light 101 irradiates the light modulation portion 601, a large amount of light rays are refracted after exiting from the light modulation portion 601 and pass through the liquid crystal 400 to the display area 301, that is, a large amount of emergent light 102 emitted from the incident light 101 through the light modulation portion 601 cannot irradiate the frame glue structure 302, so that the frame glue structure 302 can be protected from being irradiated by strong light, and the frame glue structure 302 is prevented from being volatilized, so that the pollution of a liquid crystal system or the damage of circuits in the frame glue structure 302 is avoided. The light path of the outgoing light 102 of the incident light 101 passing through the light-transmitting portion 602 is unchanged, so that the original etendue of the light path is maintained.

Compared with the related art, the embodiment shown in fig. 5 does not change the optical path of the original incident light 101, and solves the problem that the uniform incident light 101 becomes the non-uniform emergent light 102 after passing through the micro lens structure in the related art. And secondly, the optical expansion of the system is not increased, and irreversible loss is not caused to the optical system. Finally, compared with the related art, each pixel unit 301a needs to be provided with one to two microlenses, the cost of the embodiment is lower, the technology of processing the grooves is relatively mature, the yield is high, and a large amount of production and manufacturing cost can be saved.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a second embodiment of a liquid crystal display panel according to the present application. In contrast to the first embodiment of the liquid crystal panel, the sidewall of the dimming layer 600 facing the groove in fig. 6 is a convex arc surface. Similar to the effect of the first embodiment, when the incident light 101 is uniformly irradiated on the dimming layer 600, the incident light 101 is irradiated to the light-transmitting portion 602, and the incident light 101 passes through the liquid crystal 400 through the light-transmitting portion 602, is vertically irradiated to the display area 301, and is uniformly emitted; when the incident light 101 irradiates the light modulation portion 601, a large amount of light rays are refracted after exiting from the light modulation portion 601 and pass through the liquid crystal 400 to the display area 301, that is, a large amount of emergent light 102 emitted from the incident light 101 through the light modulation portion 601 cannot irradiate the frame glue structure 302, so that the frame glue structure 302 can be protected from being irradiated by strong light, and the frame glue structure 302 is prevented from being volatilized, so that the pollution of a liquid crystal system or the damage of circuits in the frame glue structure 302 is avoided. The light path of the outgoing light 102 of the incident light 101 passing through the light-transmitting portion 602 is unchanged, so that the original etendue of the light path is maintained.

Compared with the related art, the embodiment shown in fig. 6 does not change the optical path of the original incident light 101, and solves the problem that the uniform incident light 101 becomes the non-uniform emergent light 102 after passing through the micro lens structure in the related art. And secondly, the optical expansion of the system is not increased, and irreversible loss is not caused to the optical system. Finally, compared with the related art, each pixel unit 301a needs to be provided with one to two microlenses, the cost of the embodiment is lower, the technology of processing the grooves is relatively mature, the yield is high, and a large amount of production and manufacturing cost can be saved.

Referring to fig. 7, a third embodiment of a liquid crystal display panel according to the present application is shown. The sidewall of the dimming layer 600 facing the groove shown in fig. 7 has a light diffusion film. When the incident light 101 uniformly irradiates the light modulation layer 600, the incident light 101 irradiates the light transmission portion 602, and the incident light 101 passes through the liquid crystal 400 through the light transmission portion 602, vertically irradiates the display area 301, and then uniformly emits. When the incident light 101 irradiates the light modulation portion 601, a large amount of light rays are refracted after exiting from the light modulation portion 601 and pass through the liquid crystal 400 to the display area 301, that is, a large amount of light rays emitted from the incident light 101 through the light modulation portion 601 do not irradiate to the frame glue structure 302. The other part of the light is scattered after being emitted from the light adjusting portion 601, i.e. the light which is originally irradiated onto the frame glue structure 302 is further diluted, and the irradiation area of the diluted light is increased, so that the power and the optical density of the light irradiated onto the frame glue structure 302 are reduced. Meanwhile, the light path of the outgoing light 102 of the incident light 101 passing through the light-transmitting part 602 is unchanged, so that the original etendue of the light path is maintained unchanged.

Therefore, the third embodiment shown in fig. 7 can better reduce the optical power and optical density of the frame glue structure 302 compared with other embodiments, and more effectively avoid the volatilization of the frame glue structure 302, which results in pollution of the liquid crystal system or damage of the circuits in the frame glue structure 302. And the original light path of the incident light 101 is not changed, so that the problem that the uniform incident light 101 lines are converged by the micro-lens structure and then become nonuniform emergent light 102 lines in the related art is solved. And secondly, the optical expansion of the system is not increased, and irreversible loss is not caused to the optical system. Finally, the cost of the embodiment is lower, and the production and manufacturing cost can be greatly reduced.

In other embodiments, the sidewall of the dimming layer 600 facing the groove may also be hazy. In the manufacturing process, the haze may be formed by physical means, chemical etching means, laser etching means, or the like.

Referring to fig. 8, fig. 8 is a fourth embodiment of the lcd panel according to the present application. In this embodiment, the light modulation layer 600 has an astigmatic area 600a and a non-astigmatic area. The light scattering region 600a is disposed corresponding to the frame bond structure 302. In contrast to the non-scattering region, scattering particles are doped in the scattering region 600a, and the scattering particles serve as the light adjusting part 601 for diffusing light. The light-transmitting portion 602 includes a non-light-scattering region and a region other than the light-adjusting portion 601 in the light-scattering region 600 a.

When the incident light 101 uniformly irradiates on the light modulation layer 600, the incident light 101 irradiates on the non-scattering area of the light modulation layer 600, the incident light 101 passes through the liquid crystal 400 through the light modulation layer 600, vertically irradiates on the display area 301, and then uniformly emits; when the incident light 101 irradiates the light scattering area 600a, a large amount of light is scattered by the light adjusting part 601, namely, the light originally irradiated onto the frame glue structure 302 is diluted, the irradiation area of the diluted light is enlarged, and the light power and the light density irradiated onto the frame glue structure 302 are reduced, so that the frame glue structure 302 can be protected from being irradiated by strong light, and the frame glue structure 302 is prevented from being volatilized to pollute a liquid crystal system or damage a circuit in the frame glue structure 302. The light path of the outgoing light 102 of the incident light 101 passing through the non-light-scattering region and the outgoing light 102 of the incident light 101 passing through the region except the light modulation portion 601 in the light-scattering region 600a are not changed, so that the original etendue of the light path is maintained.

Compared with the related art, the embodiment shown in fig. 8 does not change the optical path of the original incident light 101, and solves the problem that the uniform incident light 101 lines in the related art become nonuniform emergent light 102 lines after being converged by the micro lens structure. And secondly, the optical expansion of the system is not increased, and irreversible loss is not caused to the optical system. Finally, compared with the related art, each pixel unit 301a needs to be provided with one to two microlenses, the cost of the present embodiment is lower, and the manufacturing cost can be greatly reduced.

Referring to fig. 9, fig. 9 is a fifth embodiment of a liquid crystal display panel according to the present application. In contrast to the fourth embodiment of the liquid crystal panel, the light modulation layer 600 of fig. 9 has a through hole 603, and the through hole 603 is opened corresponding to the frame glue structure 302. The light adjusting portion 601 is a scattering structure for scattering light, and the light adjusting portion 601 is embedded in the through hole 603.

When the incident light 101 is uniformly irradiated on the light modulation layer 600, and the incident light 101 is irradiated on the light transmission portion 602, the incident light 101 passes through the liquid crystal 400 through the light transmission portion 602, is vertically irradiated on the display area 301, and is uniformly emitted; when the incident light 101 irradiates the light adjusting portion 601, the light is scattered by the light adjusting portion 601, namely, the light originally irradiated onto the frame glue structure 302 is diluted, the irradiation area of the diluted light is enlarged, and the light power and the light density irradiated onto the frame glue structure 302 are reduced, so that the frame glue structure 302 can be protected from being irradiated by strong light, and the frame glue structure 302 is prevented from being volatilized, so that a liquid crystal system is prevented from being polluted or circuits in the frame glue structure 302 are prevented from being damaged. The light path of the outgoing light 102 of the incident light 101 passing through the light-transmitting portion 602 is unchanged, so that the original etendue of the light path is maintained.

Compared with the related art, the embodiment shown in fig. 9 does not change the optical path of the original incident light 101, and solves the problem that the uniform incident light 101 lines in the related art become nonuniform emergent light 102 lines after being converged by the micro lens structure. And secondly, the optical expansion of the system is not increased, and irreversible loss is not caused to the optical system. Finally, compared with the related art, each pixel unit 301a needs to be provided with one to two microlenses, the cost of the present embodiment is lower, and the manufacturing cost can be greatly reduced.

In some embodiments, the light modulation layer 600 is a light-transmitting panel parallel to the color film substrate 300, and the upper surface and the lower surface of the light-transmitting panel are parallel, i.e. the thickness of the light-transmitting panel is uniform, so as to ensure that the emergent light 102 irradiated to the display area 301 is uniform.

In some embodiments, the light-transmitting panel may be made of a high light-transmitting material such as transparent glass, acrylic plate, or fiber reinforced plastic.

In some embodiments, the surface of the display area 301 facing the array substrate 200 is further coated with an ITO conductive film. ITO is nano indium tin metal oxide and has good conductivity and transparency. Therefore, coating the ITO conductive film on the surface of the display region 301 can enhance conductivity and maintain transparency of the display region. A silicon dioxide barrier layer may also be plated on the surface of the display area 301 prior to sputtering the ITO layer to prevent sodium ions on the substrate glass from diffusing into the liquid crystal in the cell.
