The liquid crystal display module generally realizes the display of pictures by a liquid crystal display panel and a backlight source structure. At present, a backlight structure of conventional design is realized through Mini LED array arrangement, and a light homogenizing film and other film materials are placed on a Mini LED lamp panel (a substrate, mini LED lamp beads and protective glue) to homogenize light of the lamp panel so as to achieve a required display effect.

However, the size of the single Mini LED lamp bead is obviously larger than the pixel size, that is, the light emergent range of the Mini LED lamp bead is far larger than the image display range of the single pixel of the display panel when the Mini LED lamp bead is lighted, and since an initial deflection angle exists in the liquid crystal molecules in the liquid crystal display panel, when the panel displays a picture, the light can be emitted from the pixels of the adjacent non-display area when the Mini LED lamp bead corresponding to the pixel positioned at the edge of the picture is lighted, so that a light leakage phenomenon is caused, and a halation is formed, as shown in fig. 1, so that the use experience of a user is seriously affected.

In order to solve the above-mentioned problems, a first embodiment of the present disclosure provides a liquid crystal display module, and a schematic hierarchical structure of the liquid crystal display module is shown in fig. 2, and the liquid crystal display module mainly includes a substrate 10, a light emitting layer 20 disposed on a surface of one side of the substrate 10, a light control layer 30 disposed on a side of the light emitting layer 20 away from the substrate 10, and a liquid crystal display panel 40 disposed on a side of the light control layer 30 away from the light emitting layer 20, wherein the direction of light emitted by the light emitting layer 20 is adjusted by the arrangement of the light control layer 30, so as to avoid light leakage.

Specifically, the light-emitting layer 20 includes a plurality of beads 21 arranged in an array, and the beads 21 are mainly Mini LED beads; the light regulating layer 30 at least comprises a plurality of light regulating units 31, the number of the light regulating units 31 is the same as that of the lamp beads 21 and the light regulating units are arranged in a one-to-one correspondence manner, so that the orthographic projection of each light regulating unit 31 on the substrate 10 completely covers the orthographic projection of the corresponding lamp bead 21 on the substrate 10, and thus, the light emitted by the lamp bead 21 can be regulated in the light emitting direction through the corresponding light regulating unit 31; the liquid crystal display panel 40 at least includes a plurality of pixels 41 arranged in an array, when the liquid crystal display panel 40 actually displays a picture, the light emitted by the light beads 21 irradiates the area of the pixels 41 to realize the pixel lighting, each pixel 41 can be lighted by at least one light bead 21, that is, the front projection of each pixel 41 on the substrate 10 overlaps with the front projection of at least one light bead 21 on the substrate, when the pixel 41 is located at the juncture of two light beads 21 and even four light beads 21, the front projection of the pixel 41 on the substrate 10 overlaps with the front projection of two or four light beads 21 on the substrate 10 at the same time, and when the pixel 41 is lighted, the two or four light beads need to be lighted at the same time.

In this embodiment, the light modulation unit 31 may be implemented by the liquid crystal unit 310, and fig. 3 shows a schematic hierarchical structure of the liquid crystal unit 310. As shown in fig. 3, the liquid crystal cell 310 includes at least a first electrode plate 311 and a second electrode plate 312 disposed opposite to each other on a side of the lamp beads 21 away from the substrate 10, and liquid crystal molecules 313 are filled between the first electrode plate 311 and the second electrode plate 312. The liquid crystal molecules 313 may deflect based on the current condition of the first electrode plate 311 and the second electrode plate 312, so as to control the emergent direction of the light. Specifically, in the case that no electric field is formed between the first electrode plate 311 and the second electrode plate 312, the plurality of liquid crystal molecules 313 are randomly distributed, and the liquid crystal unit 31 is in a scattered state, as shown in fig. 4, that is, the long axis directions of different liquid crystal molecules 313 are different, at this time, when light rays are emitted from the second electrode plate 312 side, a strong light scattering state is shown, so that a light homogenizing effect can be further played, and uniformity of picture display is ensured; in the case that the first polar plate 311 and the second polar plate 312 are energized to form an electric field, as shown in fig. 5, all the liquid crystal molecules 313 deflect to make their long axes parallel to the direction of the electric field, at this time, the liquid crystal unit 31 is in a transparent straight-through state, and no light is scattered, so that all the light incident into the liquid crystal unit 31 exits along the direction perpendicular to the surface of the second polar plate 312, thereby realizing the regulation of the light exit direction and avoiding the light leakage caused by the scattering of the light in other directions.

When the display is actually performed, the driving chip determines which pixels 41 need to be lit up, which pixels 41 do not need to be lit up, or determines the gray scale condition that each pixel needs to display, in the liquid crystal display panel 40, at least according to the display to be displayed. In the present embodiment, the pixels 41 are divided into at least a first type of pixels having a first gray level and a second type of pixels having a second gray level, the first gray level being higher than the second gray level. Taking the picture as shown in fig. 1 as an example, after all the first type pixels are lightened, one X-shaped pattern is displayed, the other second type pixels are not required to be lightened, the first gray level of the first type pixels is obviously higher than the second gray level of the second type pixels, at this time, in all the first type pixels, the liquid crystal units arranged on the lamp beads corresponding to all the first type pixels adjacent to the second type pixels can be controlled to be in a straight-through state, the first type pixels adjacent to the second type pixels are pixels positioned at the edge positions of the pattern in all the first type pixels, and the liquid crystal units corresponding to the first type pixels positioned at the edge are adjusted to be in the straight-through state, so that light rays can be controlled to be emitted in the vertical direction, and the light leakage phenomenon caused by scattering the liquid crystal units to the second type pixels can be avoided; the liquid crystal units arranged on the lamp beads corresponding to the first type pixels which are not adjacent to the second type pixels in all the first type pixels are in scattering states, the first type pixels which are not adjacent to the second type pixels can be regarded as being positioned in the center of the pattern, the liquid crystal units corresponding to the first type pixels are adjusted to scattering states to play a role in homogenizing light, the uniformity of picture display is ensured, and the quantity of homogenizing light films can be saved when the liquid crystal display module level is actually arranged. Fig. 6 shows a schematic diagram of a state of a liquid crystal cell corresponding to a first pixel in the present embodiment, and as can be seen from fig. 6, the liquid crystal cell corresponding to a pixel near an edge of the pattern is set to a through state, and the liquid crystal cells corresponding to the remaining pixels are set to a scattering state.

In some embodiments, the first electrode plate 311 and the second electrode plate 312 are made of transparent conductive indium tin oxide ITO material, other materials with conductive performance and good light transmission performance can be used, and the first electrode plate 311 and the second electrode plate 312 in each liquid crystal unit 31 are controlled by independent driving circuits, and in actual use, the angle of deflection of the liquid crystal molecules 313 can be achieved by adjusting the voltages applied to the first electrode plate 311 and the second electrode plate 312. In addition, besides the liquid crystal molecules 313, the first electrode plate 311 and the second electrode plate 312 may be filled with a supporting member PS, or a transparent material such as a micro glass ball with supporting performance may be mixed between them, so as to ensure the supporting performance of the whole display module.

Fig. 7 is a schematic diagram showing another hierarchical structure of the lcd module according to the present embodiment. As shown in fig. 7, the liquid crystal display module further includes a first protective layer 51 and a second protective layer 52, wherein the first protective layer 51 is disposed between the light-modulating layer 30 and the light-emitting layer 20, the second protective layer 52 is disposed on one side of the light-modulating layer 30 away from the light-emitting layer 20, which is equivalent to the light-modulating layer 30 being sandwiched between the first protective layer 51 and the second protective layer 52, and the other side of the second protective layer 52 away from the light-modulating layer 30 can further perform the arrangement of the liquid crystal display panel 40. The arrangement of the first protective layer 51 and the second protective layer 52 can protect the light control layer 30, and can fill the gap between the light control units 31, when actually performing preparation, the first polar plate and the second polar plate of the liquid crystal unit 310 can be plated on the opposite surfaces of the first protective layer 51 and the second protective layer 52 according to the positions of the lamp beads, the filling of the liquid crystal molecules 313 is performed after the assembly of the box, and finally the first protective layer 51 and the second protective layer 52 which are combined together are pressed on the light-emitting layer 20 together with the liquid crystal unit 310 in a mould pressing mode.

It should be noted that, in the present embodiment, the first gray level and the second gray level are only used to refer to two different gray levels, which refers to the gray level difference between the pixels in the display area and the non-display area, and in general, the halo problem will be more obvious when the difference between the first gray level and the second gray level is larger, for example, the first gray level is 255, the second gray level is 0, and if the difference between the first gray level and the second gray level is smaller (for example, below 50), the first pixel and the second pixel are both emitting light, but the difference between the brightness is only the difference, so the halo problem may not be obvious, and the actual appearance of the user is not affected. Therefore, the present embodiment can be limited to use when displaying an arbitrary screen, or can be implemented only when the difference in gray scale between adjacent pixels is large, and specifically can be selected according to the actual situation, and the present embodiment is not limited.

In some embodiments, the light modulation unit 31 may further include at least an electrochromic layer 320, as shown in fig. 8, where the electrochromic layer 320 is made of electrochromic material and covers a level uniformly on the surface of the lamp bead 21, and may change to a black, gray, or other different color states based on the power-on condition, and may exhibit the characteristics of a light transmission state or a light blocking state in different colors. Specifically, the electro-optic layer 320 is in a light-transmitting state when no voltage is applied, and light can be irradiated onto the liquid crystal display panel through the electro-optic layer 320, while the electro-optic layer 320 is in a light-blocking state when no voltage is applied, and light cannot pass through the electro-optic layer 320. Therefore, when displaying the pattern, the second type pixels adjacent to the first type pixels, even the electro-active layers 320 corresponding to all the second type pixels, can be adjusted to be in the light blocking state, so that even if the light of the light bead of the first type pixels is scattered to the non-display area, the light is blocked by the electro-active layer in the light blocking state, and the halation effect is not formed.

In some embodiments, each electro-active layer 320 may be divided into a plurality of electro-active sub-areas 321, as shown in fig. 8 and 9, and fig. 9 is a schematic top view of fig. 8, where the electro-active layers 320 are uniformly divided into 9 electro-active sub-areas 321, and are arranged according to an array of 3*3, and each electro-active sub-area 321 may be independently driven to adjust its light transmission state or light blocking state, so that finer light output control on light can be achieved, and better light leakage prevention effect is ensured. In actual implementation, the electro-layer 320 corresponding to each lamp bead 21 may be connected to the lamp beads 21 through a circuit, that is, the electro-layer 320 may be powered by the power supply mode of the lamp beads 21, and the circuit is used to control whether to power the electro-layer 320, and meanwhile, the voltage value applied to the electro-layer 320 may also be controlled, and the electro-layer 320 may exhibit light transmission or light blocking characteristics with different degrees according to the applied voltage; in the case that the electro-layer 320 is divided into a plurality of electro-sub-areas 321, a circuit is provided for each electro-sub-area 321 to control whether voltage is applied, one end of each circuit is connected to the lamp bead 21, the other end is connected to a different electro-sub-area 321, and a control end of each circuit is connected to the driving chip to realize on-off of the circuit.

It should be noted that, in fig. 9, only the color blocks with different colors are used to represent each of the electro-sub-regions 321, which can be independently controlled to have different light transmission properties, and does not represent that a single electro-sub-region 321 can only actually take on a light transmission state or a light blocking state. In addition, the electrochromic material used to prepare the electrochromic layer 320 in this embodiment may be directly made of conventional materials such as polypyrrole, polythiophene, polyaniline, etc., and the embodiment is not limited thereto.

According to the embodiment, the light regulation and control layers are added in the hierarchical structure of the liquid crystal display module, the light direction emitted by the corresponding lamp beads is regulated and controlled through each light regulation and control unit, the divergence of the lamp beads corresponding to the pixels at the edge of the display picture to the pixels of other non-display areas can be avoided during actual display, the halation effect formed at the edge of the display picture is optimized, and the display effect and the use experience of the liquid crystal display module are effectively improved. Fig. 10 shows a schematic diagram of a display effect of a liquid crystal display module after an improvement of an embodiment of the disclosure, and compared with the light leakage phenomenon obvious in fig. 1, the boundary line between the lit portion and the unlit portion in fig. 10 is clear, no halation is generated, and the display effect is better.

The second embodiment of the disclosure provides an electronic device, which at least includes a liquid crystal display module according to the first embodiment of the disclosure, by adding a light modulation layer in a hierarchical structure of the liquid crystal display module, each light modulation unit modulates and controls a light ray direction emitted by a corresponding light bead, so that light pearls corresponding to pixels located at an edge of a display screen can be prevented from diverging towards pixels in other non-display areas during actual display, a halation effect formed at the edge of the display screen is optimized, and a display effect and a use experience of the liquid crystal display module are effectively improved. In practical implementation, the electronic device mainly refers to a notebook computer, a display, an intelligent television, a tablet personal computer and the like with high requirements on display effect, and the user mainly focuses on use experience in display when using the device, so that the light leakage effect of a liquid crystal display panel can be effectively improved through improvement of a liquid crystal display module in the electronic device, and the electronic device is enabled to have better overall watching use experience.
