Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display) is a type of most liquid crystal displays. Due to material limitations, TFT-LCD cannot reach an absolute off state in the dark state, so its static contrast has a technical bottleneck compared to OLED (static contrast is generally limited to ≤6000:1), and is far from reaching the contrast required by HDR, which is 10000:1 to 400000:1. At present, there is a technical means called local dimming on TFT-LCD display devices to reduce dark state light leakage and improve contrast. Such display devices are mostly direct-type backlights, with multiple LED chips tiled and spaced in an array. The backlight LED is controlled in different regions according to the display signal of the display screen. The LED brightness corresponding to the low grayscale area displayed on the corresponding display screen is reduced or even turned off. In this way, the dark state brightness can be reduced and the contrast can be achieved above 10000:1.

[0003] As the resolution of display devices gradually increases, the number of local light control zones is between tens and ten thousand. The zones cannot meet the increasing resolution and are not fine enough. In addition to the ideal display effect, except for the LEDs corresponding to the high grayscale areas that need to be displayed, the LED brightness of the remaining areas is low or turned off. However, due to the reflection inside the backlight, the actual display often causes the reflected light around the zones to form a halo, which causes interference between different zones, affecting the final display effect of different zones and causing a halo problem around the image display area on the display screen. Figure 1-2 As shown, Figure 1 The image shown by the prior art, Figure 2 Corresponding to the existing technology Figure 1 The backlighting effect of the displayed image shows that Figure 2 The number of backlight partitions and the halo effect between backlight partitions result in Figure 1 The surroundings of the displayed image are not ideally black, but rather present a whitish and shiny effect, which greatly affects the viewing experience of consumers. Therefore, the existing technology needs to be improved and developed. Summary of the invention

[0004] In view of this, the embodiments of the present invention provide a display module and a display device, which can improve the light diffusion effect between direct-type backlight partitions, reduce the halo between the backlight partitions, and thus enhance the display effect of the display module.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-2As shown, the inventors found that on the display image finally presented by the display module, for the position with higher brightness of the display image, the light-emitting elements in the corresponding area of ​​the backlight module are turned on. However, the light-emitting elements have a certain light emission angle, that is, the light emitted by two adjacent light-emitting elements may have a certain range of overlapping areas. Then, for two light-emitting elements located in different areas but adjacent to each other, when the light brightness corresponding to different areas is inconsistent, since the light emitted by the two adjacent light-emitting elements overlaps, the boundary between the two areas is in the overlapping area of ​​the light emitted by the two light elements, and the backlight module includes a reflective film material, and the display panel also includes a reflective material. There is a phenomenon of light reflection back and forth between the backlight module and the display panel, which further causes the boundaries of different areas to be blurred, that is, a halo will appear around the relatively bright area, and the relatively dark area cannot maintain the same brightness, which in turn affects the display of the display module.

[0027] The present invention provides a display module, such as Figure 3 and Figure 4 As shown, Figure 3 A schematic top view of a display module provided by an embodiment of the present invention, Figure 4 for Figure 3 A schematic cross-sectional view along section line A-A'; the display module 0 comprises a backlight module 1 and a display panel 2, wherein the backlight module 1 comprises a plurality of partitions Q, each partition Q comprises at least one light-emitting element 11, and optionally, the light-emitting elements 11 in the same partition Q are synchronously controlled, that is, the light-emitting elements 11 are electrically connected to the same signal terminal or driving circuit, and when the signal terminal or driving circuit provides a signal, the light-emitting elements 11 in the same partition Q are synchronously lit; the light-emitting elements 11 in different partitions Q are separately controlled, that is, the light-emitting elements 11 in different partitions Q are electrically connected to different signal terminals or driving circuits, and the light-emitting elements 11 in different partitions Q are lit based on the signals provided by the respective electrically connected signal terminals or driving circuits, so as to control the light-emitting elements 11 in different partitions Q to have different display brightness. The display panel 2 is located on the light emitting side of the light emitting element 11, and the display panel 2 includes a first shading portion 21. In the direction Z perpendicular to the plane where the backlight module 1 is located, the projection of the first shading portion 21 is located between two adjacent partitions Q. By setting the first shading portion 21 between the partitions Q of two adjacent backlight modules 1, the present invention blocks the light emitted by two adjacent light emitting elements 11 respectively located in two adjacent partitions Q by the first shading portion 21, thereby avoiding crosstalk between the lights of the two adjacent partitions Q and avoiding the light between the backlight module 1 and the display panel 2 from reflecting back and forth in the boundary area, thereby effectively reducing the halo between the backlight partitions Q, making the boundaries between the partitions Q relatively clear, and reducing the whitening or brightening phenomenon around the display image of the display module 0, thereby improving the display effect of the entire display module 0.

[0028] Optional, please continue to refer to Figure 4The first light shielding portion 21 is located on the surface of the display panel 2 facing the light-emitting element 11, that is, the first light shielding portion 21 is located at the bottom of the display panel 2, close to the side of the light-emitting element 11. On the one hand, it avoids adding the process of the first light shielding portion 21 inside the display panel 2 to affect the subsequent process. On the other hand, at this time, the light emitted by the light-emitting element 11 has not been diffused and reflected by the display panel 2, and can be better blocked by the first light shielding portion 21, thereby effectively reducing the halo between the backlight partitions Q, making the boundaries between the partitions Q relatively clear, and reducing the whitening or brightening phenomenon around the display image of the display module 0, thereby improving the display effect of the entire display module 0.

[0029] Optional, please continue to refer to Figure 4 The first light shielding portion 21 may be a shielding material 210, such as black ink or a black color resist material, optionally, Figure 5 and Figure 6 As shown, Figure 5 for Figure 3 Another cross-sectional diagram along the section line A-A', Figure 6 for Figure 3 Another cross-sectional schematic diagram along the section line A-A'; Figure 5 As shown, the first light shielding portion 21 may also be a reflective material 211, such as a metal material, and the reflective surface of the reflective material 211 is arranged on a side close to the light emitting element 11, or as shown in FIG. Figure 6 As shown, the first light shielding portion 21 may include two parts, wherein a part close to the light emitting element 11 is a reflective material 211, and another part away from the light emitting element 11 is a shielding material 210, and the shielding material 210 is arranged above the reflective material 211. If the reflective material 211 is metal, the reflective material 211 has a double-sided reflection characteristic, that is, it has a reflective characteristic on both the side close to the light emitting element 11 and the side away from the light emitting element 11. Then, the shielding material 210 is arranged on the side away from the light emitting element 11, which can shield the reflective material 211 from the light emitting side of the display panel 2, avoid the influence of the reflective material 211 on the display effect, and help to ensure the contrast of the displayed image. Optionally, in order to increase the adhesion between the shielding material 210 and the reflective material 211, other materials can be arranged between the two, and the present invention is not limited to this.

[0030] Optional, such as Figure 7 As shown, Figure 7 for Figure 3Another cross-sectional schematic diagram along the section line A-A'; the partition Q of the backlight module 1 includes a first partition Q1 and a second partition Q2 arranged adjacent to each other along the first direction X, the first shading portion 21 includes a first inclined surface S1 and a second inclined surface S2 arranged opposite to each other along the first direction X, the plane where the first inclined surface S1 and the second inclined surface S2 are located is not perpendicular to the plane where the display panel 2 is located, and in the third direction Z1, that is, the direction perpendicular to the plane where the display panel 2 is located, and from the side of the first shading portion 21 close to the light-emitting element 11 to the direction away from the light-emitting element 11, the projection area of ​​the first shading portion 21 gradually increases, that is, the cross-section of the first shading portion 21 in the third direction Z1 is an inverted trapezoid and an inverted triangle, that is, the first inclined surface S1 corresponds to the light-emitting element 11 in the first partition Q1, and the second inclined surface S2 corresponds to the light-emitting element 11 in the second partition Q2, as shown Figure 7 As shown, the wide-viewing angle light emitted by the light-emitting element 11 located around the first partition Q1 can be reflected by the first bevel S1, and the wide-viewing angle light emitted by the light-emitting element 11 located around the second partition Q2 can be reflected by the second bevel S2. On the one hand, the first bevel S1 and the second bevel S2 of the first shading portion 21 can reflect the light emitted by the light-emitting elements 11 located in two adjacent partitions Q to avoid crosstalk between the lights of the two adjacent partitions Q, thereby effectively reducing the halo between the backlight partitions Q and making the boundaries between the partitions Q relatively clear. On the other hand, the first bevel S1 and the second bevel S2 can reflect the light back into the corresponding first partition Q1 and the second partition Q2, such as reflecting it back between the two adjacent light-emitting elements 11 in the first partition Q1 or the second partition Q2, and then being reflected back to the light-emitting side by the optical film material of the backlight module 1, thereby improving the utilization rate of light and improving the brightness uniformity inside the partition Q.

[0031] Optional, please continue to refer to Figure 7 The first light shielding portion 21 may include a prism 212 and a metal layer 213 attached to the surface of the prism 212, wherein the prism surface includes a first inclined surface S1 and a second inclined surface S2, and the metal layer 213 is attached to the first inclined surface S1 and the second inclined surface S2, wherein the prism 212 may be a resin material or an organic material, and may be light-transmissive or light-opaque. Optionally, the prism 212 is made of light-opaque material, which can avoid reflection of the metal layer 213 toward one side of the display panel 2, avoid affecting the display effect, and help to ensure the contrast of the displayed image.

[0032] Optional, such as Figure 8 As shown, Figure 8 for Figure 3Another cross-sectional schematic diagram along the section line A-A'; the first shading portion 21 may also be a whole metal prism 214, wherein the metal prism 214 includes a first bevel S1 and a second bevel S2, which reflect the light emitted by the light-emitting element 11. Optionally, the metal prism 214 is not limited to one metal, such as a stack of multiple layers of metal materials, or an alloy or other material. The first bevel S1 and the second bevel S2 of the metal prism 214 have a higher reflectivity.

[0033] Optional, such as Fig. 9 As shown, Fig. 9 for Figure 3 Another cross-sectional schematic diagram along the section line A-A'; the metal prism 214 includes a first metal part 2141 and a second metal part 2142, wherein the first metal part 2141 is located on a side close to the light-emitting element 11, the first metal part 2141 includes a first inclined surface S1 and a second inclined surface S2, the second metal part 2142 is located on a side of the first metal part 2141 away from the light-emitting element 11, and the reflectivity of the second metal part 2142 is lower than that of the first metal part 2141, that is, the second metal part 2142 can be made of a metal with strong adhesion and low reflectivity, which can enhance the adhesion of the first metal part 2141 on the one hand, and avoid the influence of the high reflectivity of the first metal part 2141 on the display effect of the display panel 2 on the other hand, thereby ensuring the display contrast of the display module 0. Optionally, the metal prism 214 may also include only one metal, or a stack of multiple layers of metal materials, or an alloy metal, and then a shielding material 210 is set on the side of the metal prism 214 close to the display panel 2 to prevent the metal prism 214 from reflecting light toward the side of the display panel 2, thereby ensuring the display contrast of the display module 0.

[0034] Optional, please continue to refer to Figure 8 , the acute angle formed by the plane where the first inclined surface S1 is located and the plane where the display panel 2 is located is θ1, the acute angle formed by the plane where the second inclined surface S2 is located and the plane where the display panel 2 is located is θ2, 30°≤θ1≤85°, 30°≤θ2≤85°, optionally, θ1=θ2. Because the amount of light transmitted by the light-emitting element 11 is usually mostly concentrated within the oblique range of 30°, the angle between the first inclined surface S1 and the second inclined surface S2 and the plane where the display panel 2 is located is set to be greater than or equal to 30°, which can at least ensure that most of the light emitted by the light-emitting element 11 can be well reflected back into the partition Q, and the angle between the first inclined surface S1 and the second inclined surface S2 and the plane where the display panel 2 is located is set to be less than or equal to 85°, thereby ensuring that the first inclined surface S1 and the second inclined surface S2 have a certain inclination angle, thereby ensuring that almost all of the light emitted by the light-emitting element 11 can be well reflected back into the partition Q, thereby improving the brightness uniformity inside the partition Q.

[0035] Optional, see Figure 3 and Fig.10 , Fig.10 for Figure 3 Another cross-sectional schematic diagram along the section line A-A'; the backlight module 1 includes two partitions Q, a first partition Q1 and a second partition Q2, which are adjacently arranged along the first direction X, and the first shading portion 21 located between the first partition Q1 and the second partition Q2 extends along the second direction Y, wherein the first direction X and the second direction Y intersect, and at this time, the light-emitting elements 11 located in the first partition Q1 and the second partition Q2 are the first light-emitting element 111 and the second light-emitting element 112, respectively, and the distance between the two along the first direction X between the projection centers of the vertical backlight module 1 is L, and the vertical distance between the side surface of the light-emitting element 11 close to the first shading portion 21 and the side surface of the first shading portion 21 close to the light-emitting element 11 is L1( Fig.10 , then Fig.10 As shown, the side surface of the light emitting element 11 close to the first light shielding portion 21 is the first surface P1, the side surface of the first light shielding portion 21 close to the light emitting element 11 is the second surface P2, the vertical distance between the first surface P1 and the second surface P2 is L1, and the distance from the projection center of the light emitting element 11 on the plane where the first light shielding portion 21 is located to the side of the first light shielding portion 21 close to the second subarea Q2 along the first direction X is M( Fig.10 The dotted line is used in the figure), the light emitting angle of the selected light emitting element 11 is a, the maximum oblique angle is a / 2, and the distance from the first surface P1 along the maximum oblique angle of the light emitting element 11 to the first light shielding portion 21 close to the second partition Q2 is N ( Fig.10 Indicated by dotted lines), L1, M, and N can form a triangle, and the angle of the triangle is determined by the maximum oblique viewing angle a / 2 of the light-emitting element 11. At this time, M=L1×tan(a / 2) can be calculated. Assuming that the width of the first shading portion 21 in the direction perpendicular to its extension is L2, the minimum L2 should satisfy 2M-L. The optional first shading portion 21 is located in the first partition Q1 and the second partition Q2. The sizes of the areas where the first partition Q1 and the second partition Q2 are located are consistent, and the emission angles of the first light-emitting element 111 and the second light-emitting element 112 are also consistent. At this time, setting L2≥2[L1×tan(a / 2)]-L can enable the first shading portion 21 to completely block the light emitted by the light-emitting element 11, thereby effectively avoiding crosstalk between the lights of the two adjacent partitions Q, effectively reducing the halo between the backlight partitions Q, making the boundaries between the partitions Q relatively clear, and avoiding the display image of the display module 0 from being white or bright, thereby improving the display effect of the entire display module 0.

[0036] Optional, such as Fig.11 As shown, Fig.11A top view schematic diagram of another display module provided for an embodiment of the present invention; the partitions Q on the backlight module 1 are arranged in an array, and at least part of the first shading portion 21 is in a grid shape, that is, the first shading portion 21 is a continuous pattern, and its vertical projection on the plane where the backlight module 1 is located completely isolates the partitions Q, so that the light emitted by the light-emitting elements 11 of each partition Q can be relatively completely isolated, thereby avoiding crosstalk between the partitions Q, making the boundaries between the partitions Q relatively clear, avoiding the display image of the display module 0 from being white or bright, thereby improving the display effect of the entire display module 0.

[0037] Optional, please continue to refer to Fig.11 The partition Q includes a central partition Q3 and a peripheral partition Q4 at least partially surrounding the central partition Q3. The central partition Q3 is located in the central area of ​​the backlight module 1, and the peripheral partition Q4 is distributed in the peripheral area of ​​the backlight module 1. The first shading portion 21 corresponding to the central partition Q3 can be a grid-shaped portion, that is, the first shading portion 21 between each partition Q in the central area is set as a continuous pattern, thereby ensuring that each partition Q in the central area can be completely isolated, greatly reducing the light crosstalk between the partitions Q in the central area, and the first shading portion 21 corresponding to the peripheral partition Q4 can be a discontinuous pattern, that is, the first shading portion 21 of the peripheral partition Q4 is discontinuous, thereby preventing external water vapor from entering the central area along the first shading portion 21, and affecting the reliability of the display module 0. Optionally, the position of the discontinuity of the first shading portion 21 corresponding to the peripheral partition Q4 may correspond to a dark area between two adjacent light-emitting elements 11 in the peripheral partition Q4. The amount of light emitted by the light-emitting element 11 at this position is relatively small, and therefore the risk of causing optical crosstalk to the adjacent partition Q is relatively low. The first shading portion 21 is disconnected at this position and will not cause large optical crosstalk between the partitions Q, thereby ensuring the display effect of the display module 0 while also ensuring that the display module 0 has good reliability.

[0038] Optional, such as Fig.12 As shown, Fig.12 for Fig.11 A cross-sectional schematic diagram along the section line B-B'; the display panel 2 may include a first display panel 2A and a second display panel 2B, wherein the second display panel 2B is located between the first display panel 2A and the backlight module 1, wherein the first display panel 2A includes a color resistor 22, and the second display panel 2B does not include a color resistor, but retains a black matrix 23, that is, the first display panel 2A is a color display, and the second display panel 2B is a monochrome display. At this time, the first shading portion 21 is located on the side of the second display panel 2B facing the light-emitting element 11, that is, located at the bottom of the second display panel 2B. At this time, the light emitted by the light-emitting element 11 has not been diffused and reflected by the second display panel 2B, and can be better blocked by the first shading portion 21, thereby effectively reducing the halo between the backlight partitions Q.

[0039] The display area of ​​the first display panel 2A is set corresponding to the display area of ​​the second display panel 2B, and the second display panel 2B can perform corresponding regional dimming, that is, the light emitted by the backlight module 1 passes through the second display panel 2B and then passes through the first display panel 2A. For the area where the first display panel 2A displays an image or displays an area above a preset gray scale, the liquid crystal in the corresponding area of ​​the second display panel 2B rotates, and the light emitted by the backlight module 1 can pass through. For the area where the first display panel 2A does not display an image or displays an area below a preset gray scale, the liquid crystal in the corresponding area of ​​the second display panel 2B does not rotate, and the light emitted by the backlight module 1 cannot pass through. The second display panel 2B can rotate the liquid crystal at different angles according to the specific gray scale displayed by the first display panel 2A, thereby transmitting different brightness. The brightness of the picture displayed by the two display panels superimposed is more finely controlled, so that the brightness difference between the light and dark areas is increased, so that the display module 0 has a higher contrast and a more delicate image display. Optionally, the size of the pixel unit of the second display panel 2B may be greater than or equal to the size of the pixel unit of the first display panel 2A, that is, the resolution of the second display panel 2B may be less than or equal to the resolution of the first display panel 2A. The closer the resolution of the second display panel 2B is to the resolution of the first display panel 2A, the more delicate the image displayed by the display module 0 will be. Optionally, when the partition of the second display panel 2B is consistent with the partition Q of the backlight module 1, that is, the two have the same number of partitions and the same partition method, the black matrix 23 and the first shading portion 21 in the second display panel 2B can be prepared using the same mask plate, thereby reducing one mask plate and reducing production costs.

[0040] It should be noted that, in order to clearly demonstrate the features described in the present application, only one partitioning method of the display module is drawn in the figure shown in the present invention. In other embodiments of the present invention, the partitioning method of the display module may also be other methods, including equal area partitioning, unequal area partitioning, regular pattern partitioning, irregular pattern partitioning, and the setting of the first shading portion also changes with the change of the partitioning method, and the number of light-emitting elements contained in the partition can be designed according to specific size requirements and the capacity of the driving circuit, and the present invention does not impose any restrictions on this.

The display device 00 includes the above-mentioned display module 0, and the beneficial effects produced by the display device 00 are also the same as the beneficial effects described in the above-mentioned embodiments, which will not be repeated here.
