Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the application. The embodiment of the application provides a liquid crystal display panel 100, which is suitable for a display device. The display device may further include a housing 200, where the housing 200 is used to carry the liquid crystal display panel 100. Specifically, the display device may be any product or component with a display function, such as electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, etc., and the specific structure of the display device is not limited in the embodiments of the present application.

With continued reference to fig. 2, fig. 2 is a schematic structural diagram of a liquid crystal display panel of the display device shown in fig. 1. The liquid crystal display panel 100 may include an array substrate 11, a liquid crystal layer 17, a transparent cover plate 13, and a plurality of light emitting units 14. The liquid crystal layer 17 is disposed on one side of the array substrate 11, and the transparent cover plate 13 is disposed on a side of the liquid crystal layer 17 facing away from the array substrate 11. A plurality of light emitting units 14 are disposed between the liquid crystal layer 17 and the transparent cover 13, and the light emitting units 14 are configured to emit light to the transparent cover 13 to display image information. Further, after the liquid crystal display panel 100 is in the off-screen state as a whole, all or part of the light emitting units 14 may start to emit light to display image information on the transparent cover 13 in a combined manner, thereby realizing the off-screen display function of the liquid crystal display panel 100.

For example, please continue to refer to fig. 3, fig. 3 is a schematic diagram illustrating a display state of the display device of fig. 1. The light emitting unit 14 may be used to display one clock on the liquid crystal display panel 100.

Specifically, the light emitting unit 14 may include a plurality of first light emitting units 141, a plurality of second light emitting units 142, a plurality of third light emitting units 143, a plurality of fourth light emitting units 144, and a plurality of fifth light emitting units 145. First, a plurality of first light emitting units 141 are annularly arranged for displaying an outer circumference profile of a clock. Then, a plurality of second light emitting units 142 are surrounded on the inner peripheral side of the plurality of first light emitting units 141 for 1 to 60 minutes for displaying the clock. Next, a plurality of third light emitting units 143 surrounds the inner peripheral side of the plurality of second light emitting units 142 for displaying for 1 to 12 hours. Next, a plurality of fourth light emitting units 144 are disposed inside the third light emitting unit 143 for displaying logo, time zone or some other information of the display device. Finally, a plurality of fifth light emitting units 145 are used to display the hour hand and minute hand of the clock. It should be understood that, when the image information to be displayed by the light emitting units 14 is different, the arrangement of the light emitting units 14 may be varied, which is not limited by the embodiment of the present application.

With continued reference to fig. 4, fig. 4 is a schematic diagram of a first structure of the lcd panel shown in fig. 2. The liquid crystal display panel 100 may further include a color filter 12, the color filter 12 being positioned between the liquid crystal layer 17 and the transparent cover plate 13. The light emitting unit 14 is provided to the color filter 12.

Of course, the light emitting unit 14 may be provided at a position other than the color filter 12. For example, please refer to fig. 5, fig. 5 is a schematic diagram illustrating a structure of the lcd panel shown in fig. 4 after the backlight module, the first polarizer and the second polarizer are disposed. The liquid crystal display panel 100 may further include a backlight module 15, a first polarizer 16, a second polarizer 18, and the like. The first polarizer 16 is disposed on a side of the array substrate 11 facing away from the liquid crystal layer 17. The backlight module 15 is disposed at a side of the first polarizer 16 facing away from the array substrate 11. The second polarizer 18 is disposed between the color filter 12 and the transparent cover 13. The light emitting unit 14 may also be disposed on the second polarizer 18.

When the backlight module 15 starts to work, the backlight module 15 forms a surface light source and sequentially illuminates the first polarizer 16, the array substrate 11, the liquid crystal layer 17, the color filter 12, the second polarizer 18 and the transparent cover 13, and finally illuminates the whole liquid crystal display panel 100, or the backlight module 15 can realize the whole light emission and imaging of the liquid crystal display panel 100. On the contrary, when the backlight module 15 stops working, the liquid crystal display panel 100 performs a screen-off state, and the light emitting unit 14 can emit light and image independently at this time, so as to realize the screen-off display function of the liquid crystal display panel 100. That is, when the backlight module 15 stops operating, the above-described image information can be displayed in a partial area of the liquid crystal display panel 100 by the light emission of all or part of the light emitting units 14. It should be understood that the embodiment of the present application is not limited to the specific structure of the liquid crystal display panel 100. For example, the liquid crystal display panel 100 may further include some optical films, such as a brightness enhancing film, a diffusion plate, and the like, and the optical films may be disposed between the backlight module 15 and the first polarizer 16 or between the first polarizer 16 and the array substrate 11 according to actual requirements.

The technical solution of the embodiment of the present application will be further illustrated by taking the light-emitting unit 14 disposed on the color filter 12 as an example.

As shown in fig. 4, the color filter 12 includes a plurality of color filter units 121 disposed at intervals, and the front projection of each color filter unit 121 on the transparent cover 13 is at least partially offset from the front projection of the light emitting unit 14 on the transparent cover 13. Furthermore, when the light emitting unit 14 is disposed on the side of the color filter unit 121 facing the array substrate 11, it is possible to avoid that the light emitting unit 14 totally blocks the light that should be incident into one of the color filter units 121, which eventually results in incomplete image display or color deviation of the liquid crystal display panel 100. Alternatively, when the light emitting unit 14 is disposed on the side of the color filter unit 121 facing the transparent cover 13, it is avoided that the light emitting unit 14 completely blocks the transmitted light of one color filter unit 121, which ultimately results in incomplete image display or color deviation of the liquid crystal display panel 100.

The color filter unit 121 may include a green filter unit 1211, a blue filter unit 1212, and a red filter unit 1213. Here, the green filter unit 1211 may be a color block capable of transmitting green light, the blue filter unit 1212 may be a color block capable of transmitting blue light, and the red filter unit 1213 may be a color block capable of transmitting red light. It will be appreciated that the combination of red, green and blue is referred to as the optical three primary colors (RGB), which, when mixed, constitute the display screen display colors. Specifically, at least one green filter unit 1211, at least one blue filter unit 1212 and at least one red filter unit 1213 may together form a pixel structure, and finally, a plurality of pixel structures together form an imaging screen of the liquid crystal display. The green filter units 1211, the blue filter units 1212 and the red filter units 1213 of each pixel structure may be arranged in a straight line direction, may be distributed in a triangle shape, may be arranged in a masonry shape, a tripod shape or a windmill shape, and the arrangement manner of the color filter units 121 of different types is not limited in the embodiment of the present application.

Alternatively, the color filter unit 121 may further include a white filter unit. The white filter unit may be a color block capable of transmitting white light, and further, the green filter unit 1211, the blue filter unit 1212, the red filter unit 1213, and the white filter unit collectively form a pixel structure of RWGB. In the pixel structure of RWGB, a white filter unit with extremely high transmittance is added, so that the brightness of the liquid crystal display panel 100 can be greatly improved. It is to be understood that the embodiment of the present application is not limited to the specific type and arrangement of the color filter units 121.

In some embodiments, at least a portion of the light emitting units 14 are adjacent to the green filter unit 1211. Specifically, the individual light emitting units 14 may be adjacent to the green filter unit 1211, or all the light emitting units 14 may be adjacent to the green filter unit 1211, which is not limited in the embodiment of the present application. The light emitting unit 14 may be directly fixed on the green filter unit 1211 by abutting the green filter unit 1211, or the light emitting unit 14 may be located beside the green filter unit 1211 and not directly contacted with the green filter unit 1211, which is not limited in the embodiment of the present application.

It will be appreciated that, on the one hand, the light emitting unit 14 as a three-dimensional component necessarily occupies a certain space, that is, the light emitting unit 14 necessarily causes a certain shielding for the light transmitted by the adjacent color filter unit 121, or a certain shielding for the light directed to the adjacent color filter unit. On the other hand, since the wavelength of green light is short, the transmission capability is strong, so that the light energy of green light transmitted by the green filter unit 1211 is strong and the luminance is large. Then, compared to the light emitting unit 14 disposed beside the red filter unit 1213 and the blue filter unit 1212, the light emitting unit 14 in the embodiment of the application has relatively less influence on the light transmitted by the green filter unit 1211, so that the light emitting unit 14 has less interference on the whole pixel structure.

Of course, in some other embodiments, the light emitting unit 14 may be disposed beside the blue filter unit 1212 or the red filter unit 1213. Alternatively, when the color filter unit 121 further includes a white filter unit, the light emitting unit 14 may be disposed beside the white filter unit, and the interval between the light emitting unit 14 and the different types of color filter units 121 is not limited in the embodiment of the present application.

With continued reference to fig. 6 and fig. 7, fig. 6 is a schematic structural diagram of an array substrate of the lcd panel shown in fig. 4, and fig. 7 is a schematic structural diagram of a light emitting unit of the lcd panel shown in fig. 4. The array substrate 11 may include a plurality of thin film transistors 111, and each light emitting unit 14 is disposed opposite to one thin film transistor 111. It can be understood that, since the thin film transistor 111 is opaque, the portion of the array substrate 11 provided with the thin film transistor 111 cannot transmit the light of the backlight module 15. In this way, the light emitting unit 14 is disposed opposite to the thin film transistor 111, so that shielding of the light transmitted by the array substrate 11 by the light emitting unit 14 can be reduced, and further, the imaging quality of the liquid crystal display panel 100 can be improved.

In combination with the above-mentioned light emitting unit 14 being adjacent to the green filter unit 1211, the plurality of thin film transistors 111 are in one-to-one correspondence with the plurality of color filter units 121, and then each green filter unit 1211 is also disposed in correspondence with one thin film transistor 111. Wherein, each green filter unit 1211 includes a first portion 1211a opposite to the corresponding thin film transistor 111, and the light emitting unit 14 is at least partially disposed on the first portion 1211a.

Specifically, the array substrate 11 may further include a second transparent substrate 112, a metal wiring layer 113, and a plurality of sub-pixel electrodes 114. The metal wiring layer 113 is disposed on a side of the second transparent substrate 112 facing the color filter 12. The metal wiring layer 113 is separated by a plurality of mutually independent sub-pixel regions, and each sub-pixel region is opposite to one color filter unit 121. Each of the sub-pixel regions is provided with one of the above-described thin film transistors 111 and one of the sub-pixel electrodes 114, and the thin film transistor 111 in each of the sub-pixel regions is electrically connected to the sub-pixel electrode 114. At this time, the color filter 12 further includes a second portion 1211b offset from the thin film transistor 111.

It can be understood that, since the thin film transistor 111 is opaque, the portion of the array substrate 11 provided with the thin film transistor 111 cannot transmit the light of the backlight module 15. Thus, the first portion 1211a of the green filter unit 1211 does not emit light, or only weak light is emitted to the first portion 1211a, and most or all of the light emitted to the green filter unit 1211 is emitted to the second portion 1211b. That is, the first portion 1211a of the green light-filtering unit 1211 has substantially no effect or only a very small effect on the light emission of the green light-filtering unit 1211. At this time, the first portion 1211a is used to provide the light emitting unit 14, and the installation space of the light emitting unit 14 may be increased as much as possible while reducing the interference of the light emitting unit 14 with the color filter unit 121, so as to reduce the installation difficulty of the light emitting unit 14.

In some embodiments, the color filter 12 may also include a black matrix 122. The black matrix 122 is provided with a plurality of hollowed-out areas facing the array substrate 11. The color filter units 121 are in one-to-one correspondence with the hollow areas, and each color filter unit 121 is at least partially disposed in the corresponding hollow area. For example, each color filter unit 121 partially protrudes outside the hollow area, or each color filter unit 121 is completely contained in the hollow area, or each individual color filter unit 121 partially protrudes outside the hollow area, and each individual color filter unit 121 is completely contained in the hollow area. On the one hand, the black matrix 122 can avoid the degradation of the imaging quality of the liquid crystal display panel 100 caused by the light leakage between the different color filter units 121; on the other hand, the black matrix 122 may increase the contrast between the different color filter units 121 to improve the imaging quality of the liquid crystal display panel 100.

With continued reference to fig. 8, fig. 8 is a schematic diagram of a second structure of the lcd panel shown in fig. 2. The light emitting unit 14 is at least partially disposed on a surface of the color filter unit 121 facing the array substrate 11.

Illustratively, the green filter unit 1211 described above includes a first portion 1211a and a second portion 1211b. The first and second portions 1211a and 1211b may form one step surface toward one side surface of the array substrate 11. The distance between the first portion 1211a and the array substrate 11 is greater than the distance between the second portion 1211b and the array substrate 11, and different light emitting units 14 are respectively fixed on one side surface of the first portion 1211a of the different green filter units 1211 facing the array substrate 11. At this time, it may also be understood that the green filter unit 1211 forms a notch at the first portion 1211a toward one side of the array substrate 11, and the light emitting unit 14 is received in the notch. Further, compared to the first portion 1211a and the second portion 1211b being substantially flush toward a side surface of the array substrate 11, the embodiment of the application can reduce the thickness of the color filter 12 as a whole.

Of course, the light emitting units 14 may be partially disposed on a side surface of the first portion 1211a facing the array substrate 11 and partially disposed on the black matrix 122, and the light emitting units 14 may be partially disposed on a side surface of the first portion 1211a facing the array substrate 11 and partially disposed on a side surface of the second portion 1211b facing the array substrate 11.

It is understood that, when the light emitting unit 14 is disposed at a side surface of the green filter unit 1211 facing the array substrate 11, the light emitting unit 14 may be a light emitting unit 14 emitting light of white or green in order to allow light generated by the light emitting unit 14 to pass through the green filter unit 1211.

It is further understood that, when the light emitting units 14 are disposed on the surface of the green filter unit 1211 facing the array substrate 11, the divergence angle of the emitted light of the light emitting units 14 may be limited by the black matrix 122, so that the divergence angle of the light emitted by each light emitting unit 14 through the green filter unit 1211 is smaller, and thus mutual crosstalk between the emitted light of different light emitting units 14 is reduced.

Alternatively, please refer to fig. 9, fig. 9 is a schematic diagram illustrating a third structure of the lcd panel shown in fig. 2. The light emitting unit 14 may be at least partially disposed on a side surface of the color filter unit 121 facing away from the array substrate 11. Then, the light emitted from the light emitting unit 14 is not filtered by the color filter unit 121, so that the light emitting unit 14 can emit light of any color without being limited by the color filter unit 121.

Illustratively, the green filter unit 1211 described above includes a first portion 1211a and a second portion 1211b. The first portion 1211a and the second portion 1211b may form a stepped surface toward a side surface of the transparent cover plate 13. The distance between the first portion 1211a and the transparent cover plate 13 is greater than the distance between the second portion 1211b and the transparent cover plate 13, and different light emitting units 14 are respectively fixed on one side surface of the first portion 1211a of the different green filter units 1211, which faces the transparent cover plate 13. At this time, it may also be understood that a notch is formed at the first portion 1211a on the side of the green filter unit 1211 facing the transparent cover 13, and the light emitting unit 14 is received in the notch; further, compared to the first portion 1211a and the second portion 1211b being substantially flush with a side surface facing the transparent cover 13, the thickness of the color filter 12 can be reduced.

Alternatively, in some other embodiments, a side surface of the first portion 1211a and the second portion 1211b facing the transparent cover plate 13 may be substantially flush, and the different light emitting units 14 are respectively fixed to a side surface of the first portion 1211a of the different green filter unit 1211 facing the transparent cover plate 13, which is not limited by the embodiment of the present application.

Of course, the light emitting unit 14 may be partially disposed on a side surface of the first portion 1211a facing the transparent cover 13 and partially disposed on the black matrix 122, and the light emitting unit 14 may be partially disposed on a side surface of the first portion 1211a facing the transparent cover 13 and partially disposed on a side surface of the second portion 1211b facing the transparent cover 13.

With continued reference to fig. 10, fig. 10 is a schematic diagram of a fourth structure of the lcd panel shown in fig. 2. In some other embodiments, the light emitting units 14 may be all disposed on a side of the black matrix 122 facing away from the array substrate 11.

In some embodiments, the light emitting unit 14 may be configured such that at least part of the light emitting unit 14 emits light at the same time when the backlight module 15 emits light. Furthermore, the backlight module 15, the array substrate 11, the liquid crystal layer 17, the color filter 12 and some other optical film layers can cooperate to display the main image of the liquid crystal display panel 100. The partially lighted lighting unit 14 may constitute a number of superimposed imaging frames displayed in synchronization with the main imaging frame.

For example, the light emitting unit 14 may be used to perform brightness compensation for a corresponding color filter unit 121 (such as a blue filter unit 1212 or a red filter unit 1213). That is, the superimposed imaging picture can be used for brightness compensation for the main imaging picture.

In some embodiments, the color filter 12 may further include a first transparent substrate 123 such as a glass substrate. The first transparent substrate 123 is disposed on the black matrix 122 and on the side of all the color filter units 121 facing the transparent cover 13, and serves as a substrate for the whole color filter 12.

Specifically, the liquid crystal display panel 100 includes the second polarizer 18, and the transparent cover 13 may be attached to the second polarizer 18.

When the light emitting unit 14 is disposed on the side of the black matrix 122 facing the transparent cover 13 or the side of the color filter unit 121 facing the transparent cover 13, the light emitting unit 14 may be bonded to the first transparent substrate 123, and then the black matrix 122 and the color filter unit 121 are formed on the first transparent substrate 123 in sequence, so that the light emitting unit 14 is disposed on the side of the black matrix 122 facing the transparent cover 13 or the side of the color filter unit 121 facing the transparent cover 13.

The color filter 12 may further include a protective layer 124 and a transparent conductive layer 125. The protection layer 124 is disposed on the side of the black matrix 122 and the side of all the color filter units 121 facing away from the transparent cover plate, so as to provide insulation protection. The transparent conductive layer 125 is disposed on a side of the protective layer 124 facing away from the black matrix 122. Further, a voltage may be applied to a portion of the liquid crystal material of the liquid crystal layer 17 located therebetween by cooperation of the transparent conductive layer 125 and the subpixel electrode 114 of the array substrate 11 to control deflection of the liquid crystal material of the liquid crystal layer 17. The transparent conductive layer may be any transparent conductive material such as ITO (Indium Tin Oxide).

In some embodiments, to achieve control of the light emitting unit 14, the light emitting unit 14 may be electrically connected to a control circuit board such as a logic board of the display device or a power supply.

In order to realize the wiring and electrical control of the light emitting unit 14, the liquid crystal display panel 100 further includes a first conductive member 19a. The first conductive member 19a is laid on the black matrix 122. One end of the first conductive member 19a is electrically connected to the light emitting unit 14, and the other end of the first conductive member 19a extends to the outside of the color filter 12, so that a control circuit board or a power supply outside the color filter 12 can control the light emitting unit 14 through the first conductive member 19a. It can be appreciated that the first conductive member 19a is laid on the black matrix 122, so that the first conductive member 19a can avoid blocking the light transmitted by the color filter unit 121, and further the display effect of the liquid crystal display panel 100 can be improved.

Specifically, when the light emitting unit 14 is at least partially disposed on a side surface of the green filter unit 1211 facing the transparent cover 13, the first conductive member 19a may be disposed on a side surface of the black matrix 122 facing the transparent cover 13, or may be disposed on a side surface of the black matrix 122 facing away from the transparent cover 13 after penetrating the black matrix 122. When the light emitting unit 14 is at least partially disposed on a side surface of the green filter unit 1211 facing the array substrate 11, the first conductive member 19a may be disposed on a side surface of the black matrix 122 facing the array substrate 11, or may be disposed on a side surface of the black matrix 122 facing away from the array substrate 11 after penetrating the black matrix 122.

The first conductive member 19a may include a plurality of first conductive lines and a plurality of second conductive lines. Each light emitting unit 14 may be connected to a power source through one or more first wires and grounded through one second wire. Further, the switching control of the light emitting unit 14 can be achieved by the cooperation of the first wire and the second wire.

It is to be understood that the first conductive member 19a may also be a transparent conductive material partially covering the color filter unit 121, which is not limited in the embodiment of the present application.

With continued reference to fig. 11, fig. 11 is a schematic structural diagram of the transparent conductive layer of the color filter shown in fig. 4. The liquid crystal display panel 100 may further include a second conductive member 19b to enable control of the light emitting unit 14.

Specifically, the second conductive member 19b is provided on the transparent conductive layer 125, and the second conductive member 19b is insulated from the transparent conductive layer 125. One end of the second conductive member 19b penetrates the protective layer 124 and the black matrix 122 and is electrically connected to the light emitting unit 14. The other end of the second conductive member 19b extends to the outside of the color filter 12 so that a control circuit board or a power supply outside the color filter 12 can control the light emitting unit 14 through the second conductive member 19 b.

The second conductive member 19b may include a plurality of third wires and a plurality of fourth wires, for example. Each light emitting unit 14 is connected to a power source through one or more third wires and is grounded through a fourth wire. Further, the switching control of the light emitting unit 14 can be achieved by the cooperation of the third wire and the fourth wire.

The orthographic projection of the portion of the second conductive member 19b disposed on the transparent conductive layer 125 may be located in the black matrix 122, so as to avoid the shielding of the second conductive member 19b to the light beam emitted to the color filter unit 121, and further improve the display effect of the liquid crystal display panel 100. Of course, the front projection of the second conductive member 19b on the first transparent substrate 123 may also be partially or completely offset from the black matrix 122, which is not limited in the embodiment of the present application.

The second conductive member 19b may be disposed between the transparent conductive layer 125 and the protective layer 124, or the second conductive member 19b may be disposed on a side of the transparent conductive layer 125 opposite to the protective layer 124, which is not limited in the embodiment of the present application.

Alternatively, the transparent conductive layer 125 may be provided with routing channels 1251. The second conductive member 19b is partially accommodated in the routing channel 1251. Compared to the second conductive member 19b laid on the surface of the transparent conductive layer 125, the thickness of the color filter 12 can be reduced in the embodiment of the application, so that the liquid crystal display panel 100 is thinner.

Specifically, transparent conductive layer 125 may include a plurality of sub-transparent conductive layers 1252 disposed at intervals. Each sub-transparent conductive layer 1252 is connected to the protective layer 124, and a wiring channel 1251 is defined between two adjacent sub-transparent protective layers 124.

In some embodiments, the light emitting unit 14 may be a Micro LED (Micro light emitting diode) lamp bead. It can be appreciated that, since the Micro LED lamp beads have extremely small volume, the light shielding caused by the excessive volume of the light emitting unit 14 to the light transmitted by the color filter unit 121 can be better avoided.

In some embodiments, the light emitting unit 14 may be adhesively fixed with the black matrix 122 and/or the color filter unit 121. Specifically, if the light emitting units 14 are all provided on the color filter unit 121, the light emitting units 14 may be bonded and fixed to the color filter unit 121; if all the light emitting units 14 are disposed on the black matrix 122, the light emitting units 14 may be adhered and fixed to the black matrix 122. When the light emitting unit 14 is partially disposed in the color filter unit 121 and partially disposed in the black matrix 122, the light emitting unit 14 may be selectively bonded and fixed to at least one of the black matrix 122 and the color filter unit 121, which is not limited in the embodiment of the present application. Of course, the light emitting unit 14 may be fixed on the black matrix 122 and/or the color filter unit 121 by other methods, which is not limited in the embodiment of the present application.
