[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application with application number 202311667743.X and application name “Display Panel and Display Device” filed with the China Patent Office on December 5, 2023, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0004] As living standards improve, people have increasingly higher requirements for the resolution of display panels. Resolution is mainly achieved by increasing the number of pixels per inch (PPI), but as the number of pixels increases, the pixel opening area decreases, while the black matrix's blocking area for the pixels remains unchanged. VR display panels, in particular, have higher resolution requirements than ordinary display panels. For example, for a 1500PPI display panel, if the color resist size is not changed and the 4×4um size is still used, the pixel opening will be too small, and the black matrix's blocking area for the pixels will be indirectly increased. When displaying, if you want to display images with high brightness or high contrast, you need to provide more power, and the display panel will have problems with excessive power consumption and severe heat generation.

[0005] In related technologies, the pixel opening is increased by changing the size of the color resist from 4×4μm to 3×5μm. However, this method requires more refined color resist production, and the material has process limitations, greatly increasing the difficulty and risk of color resist production. SUMMARY OF THE INVENTION

[0006] This application aims to improve the resolution without changing the size of the color resist and reduce the shading area of ​​the black matrix.

[0007] In a first aspect, embodiments of the present application disclose a display panel, comprising:

[0008] an array substrate, wherein pixel driving electrodes are provided on the array substrate;

[0009] A color filter substrate, the color filter substrate being arranged opposite to the array substrate, the color filter substrate comprising a black matrix and a color resist located within the black matrix;

[0010] a liquid crystal layer, provided between the array substrate and the color filter substrate, the liquid crystal layer comprising a plurality of liquid crystals;

[0011] Among them, an induction electrode is provided in the liquid crystal layer, which is located at at least one end of the color resistance and forms an induction electric field with the pixel driving electrode. The induction electric field drives the liquid crystal blocked by the black matrix to be arranged close to the color resistance and present in a light-shielding state.

[0012] In a second aspect, an embodiment of the present application discloses a display device, wherein the display device includes a display panel, and the display panel includes:

[0013] an array substrate, wherein pixel driving electrodes are provided on the array substrate;

[0014] A color filter substrate, the color filter substrate being arranged opposite to the array substrate, the color filter substrate comprising a black matrix and a color resist located within the black matrix;

[0015] a liquid crystal layer, provided between the array substrate and the color filter substrate, the liquid crystal layer comprising a plurality of liquid crystals;

[0016] Among them, an induction electrode is provided in the liquid crystal layer, which is located at at least one end of the color resistance and forms an induction electric field with the pixel driving electrode. The induction electric field drives the liquid crystal blocked by the black matrix to be arranged close to the color resistance and present in a light-shielding state. Beneficial effects

[0017] The embodiments of the present application provide a display panel and a display device, which mainly form an electric field by arranging an induction electrode in the liquid crystal layer. The induction electrode and the pixel driving electrode form an electric field. The electric field drives the liquid crystal to be arranged close to the color resistance, so that the liquid crystal is closer to the light-shielding portion of the black matrix. The light-shielding portion can block more light. When the light-shielding amount remains unchanged, the area required for light shielding is reduced, thereby reducing the size of the light-shielding portion and increasing the size of the light-transmitting opening. On the basis of improving the resolution of the display panel without changing the color resistance size, the requirements of high brightness and high contrast of the display panel can be met. Under the same high brightness or high contrast, the power consumption and heat generation of the display panel proposed in the present application are lower. Specifically, pixel drive electrodes are provided on the array substrate to form an electric field. A black matrix and color resist are then provided within the liquid crystal layer. The black matrix is ​​primarily used for shielding light to prevent light leakage. The color resist is used to support the array substrate and the color filter substrate, enabling a liquid crystal layer to be formed between the array substrate and the color filter substrate. An induction electrode is then provided on at least one side of the color resist. The induction electrode interacts with the pixel drive electrode to form an electric field. The electric field force acts on the liquid crystal, driving the liquid crystal to move toward the color resist, causing the liquid crystal to align closer to the color resist. This results in the liquid crystal being closer to the color resist. That is, for the same black matrix area, when the black matrix is ​​projected toward the array substrate, the light leakage angle is reduced because the liquid crystal is closer to the color resist. This projection covers a greater amount of liquid crystal, and the amount of light reflected and projected by the liquid crystal is greater than in the prior art. While achieving the same amount of light shielding as in the prior art, the black matrix's shielding area can be optionally reduced compared to the prior art, thereby increasing the area of ​​the light-transmitting opening. This allows for high brightness and high contrast display effects at high resolution, without causing severe heat generation or excessive power consumption due to high brightness or high contrast. The preset light leakage amount here is the light leakage amount that needs to be blocked by the black matrix in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

Modes for Carrying Out the Invention

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0025] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of the present application with unnecessary detail. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

[0026] Please refer to Figures 1 to 4. The embodiment of the present application provides a display panel, which can be a folding display panel or a non-folding display panel; the display panel can be an ordinary display panel or a VR (Virtual Reality) display panel. This application does not limit this. As long as the display panel can drive the liquid crystal to be arranged close to the color resistance 5 through the induction electrode 31, the purpose of reducing the light-shielding area of ​​the black matrix 4 and increasing the area of ​​the light-transmitting opening 42 can be achieved. In addition, the display panel can be applied to mobile phones, computers, tablets, VR devices, etc., so that the device can achieve high brightness and high contrast while improving the resolution. Specifically, the display panel includes:

[0027] An array substrate 1 , on which pixel driving electrodes 11 are provided;

[0028] A color filter substrate 2 is disposed opposite the array substrate 1 and includes a black matrix 4 and color resists 5 within the black matrix 4. The black matrix 4 includes a plurality of light shielding portions 41 and a plurality of light-transmitting openings 42 separated by the light shielding portions 41. Each color resist 5 is disposed on a side of each light shielding portion 41 facing away from the color filter substrate 2.

[0029] The liquid crystal layer 3 is provided between the array substrate 1 and the color filter substrate 2, and the liquid crystal layer 3 includes a plurality of liquid crystals;

[0030] Among them, an induction electrode 31 is provided in the liquid crystal layer 3. The induction electrode 31 is located at at least one end of the color resist 5 and forms an induction electric field with the pixel driving electrode 11. The induction electric field drives the liquid crystal blocked by the black matrix 4 to be arranged close to the color resist 5 and present in a light-shielding state, so that the light-shielding portion 41 blocks a preset amount of light leakage.

[0031] The technical solution provided by the present application is mainly achieved by setting an induction electrode 31 on the liquid crystal layer 3. The induction electrode 31 and the pixel driving electrode 11 form an electric field. The electric field drives the liquid crystal to be arranged close to the color resistance 5, so that the liquid crystal is closer to the shading portion 41 of the black matrix 4. The shading portion 41 can block more light. When the amount of shading remains unchanged, the area that needs to be shaded is reduced, thereby reducing the size of the shading portion 41 and increasing the size of the light-transmitting opening 42. This achieves the goal of improving the resolution of the display panel without changing the size of the color resistance 5, while meeting the requirements of high brightness and high contrast images of the display panel. Under the same high brightness or high contrast, the power consumption and heat generation of the display panel proposed in the present application are lower. Specifically, pixel drive electrodes 11 are provided on the array substrate 1 to form an electric field. A black matrix 4 and color resists 5 are then provided within the liquid crystal layer 3. The black matrix 4 primarily shields light to prevent light leakage. The color resists 5 support the array substrate 1 and the color filter substrate 2, enabling the liquid crystal layer 3 to be formed between the array substrate 1 and the color filter substrate 2. An induction electrode 31 is then provided on at least one side of the color resist 5. The induction electrode 31 interacts with the pixel drive electrode 11 to form an electric field. The electric field force exerted on the liquid crystals drives the liquid crystals toward the color resists 5, causing them to align near the color resists 5. Compared to the prior art, the liquid crystals are closer to the color resists 5. That is, given the same black matrix 4 area, when the black matrix 4 is projected toward the array substrate 1, the light leakage angle is reduced because the liquid crystals are closer to the color resists 5. This increases the amount of liquid crystals covered by the projection and the amount of light reflected and projected by the liquid crystals. While meeting the required light shielding, the light shielding area of ​​the black matrix 4 can be further reduced, thereby increasing the area of ​​the light-transmitting opening 42. At high resolution, high brightness and high contrast display effects can be achieved, and the display panel will not generate severe heat or consume excessive power due to high brightness or high contrast.

[0032] It should be noted that the preset light leakage amount here refers to the light leakage amount that needs to be blocked in the prior art. Generally speaking, the main technical concept of this application is to use the induction electrode 31 and the pixel drive electrode 11 to form an electric field. The electric field drives the liquid crystal to align close to the color resist 5, so that more liquid crystal is located below the light shielding portion 41, reducing the light leakage angle. Therefore, the area of ​​the light shielding portion 41 can be reduced while still blocking the preset light leakage amount. Then, while meeting the preset light shielding amount, the light-transmitting opening 42 is increased to achieve the purpose of improving brightness and contrast.

[0033] In some embodiments, the pixel driving electrode 11 includes a common electrode 111 and a pixel electrode 112. The common electrode 111 is disposed between the pixel electrode 112 and the induction electrode 31. The three different electrodes can be applied with the same or different voltages, thereby forming different electric fields to meet the different light shielding requirements of the display panel when in the white display state and the black display state. All of the following embodiments are implemented under the structure described above for the pixel driving electrode 11.

[0034] Referring to Figure 1 , in some embodiments, the induction electrode 31 is disposed on the side of the color resist 5 facing the array substrate 1 and is disposed opposite the pixel drive electrode 11. By disposing the induction electrode 31 on the side of the color resist 5 facing the array substrate 1, the induction electrode 31 is positioned close to the pixel drive electrode 11, making it easier to form an electric field. By setting the voltages of the induction electrode 31 and the pixel drive electrode 11, the direction of the electric field can be controlled, thereby controlling the direction of liquid crystal movement. In this embodiment, to move the liquid crystal toward the color resist 5, the direction of the electric field can be directed toward the color resist 5. Furthermore, because the induction electrode 31 is disposed on the side of the color resist 5 facing the array substrate 1, that is, the induction electrode 31 is relatively close to the array substrate 1, the direction of the electric field acting on the liquid crystal is also closer to the array substrate 1, causing the liquid crystal to align closer to the array substrate 1 and the color resist 5.

[0035] Referring to Figure 2 , in some embodiments, the induction electrode 31 is disposed between the color resist 5 and the light shielding portion 41, and is positioned opposite the pixel driving electrode 11. By disposing the induction electrode 31 between the color resist 5 and the light shielding portion 41, the distance between the induction electrode 31 and the pixel driving electrode 11 is increased, and the range of the electric field force is also larger than in the previous embodiment. This allows the liquid crystal to more easily align close to the color resist 5, and the liquid crystal is better subjected to the force.

[0036] Referring to Figure 3 , in some embodiments, a protrusion 12 is provided on the side of the array substrate 1 facing the color filter substrate 2. The protrusion 12 is positioned opposite the color resist 5, and the induction electrode 31 is positioned on the protrusion 12 and opposite the pixel drive electrode 11. The protrusion 12 is a structure formed on the transparent conductive layer. By utilizing the protrusion 12 to elevate the position of the induction electrode 31, the induction electrode 31 no longer needs to be positioned on the color resist 5 to achieve an opposing arrangement between the induction electrode 31 and the pixel drive electrode 11. Positioning the induction electrode 31 on the protrusion 12 can still achieve an opposing arrangement and generate an electric field that aligns the liquid crystal near the color resist 5. This provides more possibilities for the placement of the induction electrode 31.

[0037] Referring to Figure 4 , in some embodiments, the induction electrode 31 can also wrap around the surface of the color resist 5, that is, the entire surface of the color resist 5 is provided with the induction electrode 31. This allows the electric field formed by the induction electrode 31 to have a wider coverage area, which is beneficial for driving the liquid crystal. However, this arrangement presents certain difficulties in the manufacturing process. Similarly, in addition to being provided on only one side of the color resist 5 or wrapping the entire surface of the color resist 5 as described above, the induction electrode 31 can also be provided on multiple sides of the color resist 5. For example, if the color resist 5 has four side surfaces and a bottom surface, the induction electrode 31 can be provided on the bottom surface and one, two, three, or four of the four side surfaces, etc., without limitation.

[0038] The above embodiments disclose a variety of configuration schemes for the induction electrode 31 , all of which are independent configuration schemes. In actual application, one of the schemes can be selected for implementation without limitation.

[0039] Furthermore, because the inductive electrode 31 is positioned above the common electrode 111 in each of the aforementioned embodiments along the direction from the array substrate 1 toward the color filter substrate 2, the pixel electrode 112, the common electrode 111, and the inductive electrode 31 are sequentially arranged along the direction from the array substrate 1 toward the color filter substrate 2. Therefore, two voltage setting examples are provided below, both of which are applicable to the solutions disclosed in each of the aforementioned embodiments.

[0040] When the display panel is in a white display state, the induction electrode 31, the pixel electrode 112, and the common electrode 111 jointly form a first electric field. The electric field force of the first electric field on the liquid crystal is directed toward the color resist 5, causing the liquid crystal to align close to the color resist 5. When the display panel is in a white display state, its light shielding requirement is less than that in a black display state. The voltage of the induction electrode 31 is set to 2V, the voltage of the common electrode 111 is set to 0.2V, and the voltage of the pixel electrode 112 is set to 5V. The three voltages work together to form an electric field directed toward the color resist 5. Of course, the voltages of the induction electrode 31, the common electrode 111, and the pixel electrode 112 can all be set to other values, as long as the voltage of the induction electrode 31 is greater than the voltage of the common electrode 111, and the voltage of the pixel electrode 112 is greater than the voltage of the induction electrode 31. In this way, a suitable voltage difference can be formed between the pixel electrode 112 and the induction electrode 31, thereby generating an electric field directed toward the color resist 5.

[0041] When the display panel is in a black display state, the induction electrode 31, the pixel electrode 112, and the common electrode 111 jointly form a second electric field. The second electric field acts on the liquid crystals with an electric field force directed toward the color resist 5, causing the liquid crystals to align close to the color resist 5. The electric field force of the first electric field is smaller than the electric field force of the second electric field, ensuring that the black display state requires greater light shielding than the white display state. When the display panel is in a black display state (dark state), the voltage of the induction electrode 31 is set to 0V, the voltage of the common electrode 111 is set to 0.2V, and the voltage of the pixel electrode 112 is set to 5V. These three voltages work together to form an electric field directed toward the color resist 5. Of course, the voltages of the induction electrode 31, the common electrode 111, and the pixel electrode 112 can all be set to other values, as long as the voltage of the induction electrode 31 is lower than the voltage of the common electrode 111, and the voltage of the pixel electrode 112 is higher than the voltage of the induction electrode 31 and higher than the voltage of the common electrode 111. In this way, a voltage difference greater than the voltage difference in the white display state can be formed between the pixel electrode 112 and the induction electrode 31, thereby generating an electric field toward the color resistor 5.

[0042] In some embodiments, the color resist 5 includes multiple primary color resists 51 and multiple secondary color resists 52. The primary color resists 51 are arranged around the edge of the color filter substrate 2, enclosing an area, and the secondary color resists 52 are located within this area. Both the primary color resists 51 and the secondary color resists 52 are used to support the color filter substrate 2 and the array substrate 1. The length of the primary color resists 51 along the direction from the array substrate 1 to the color filter substrate 2 is greater than that of the secondary color resists 52, so that the primary color resists 51 provide greater support than the secondary color resists 52.

[0043] Optionally, the induction electrodes 31 include multiple main induction electrodes 311 and multiple sub-induction electrodes 312. Each main induction electrode 311 is located on at least one side of a primary color resist 51, and each sub-induction electrode 312 is located on at least one side of a sub-color resist 52. By providing the induction electrodes 31 on both the primary color resist 51 and the sub-color resist 52, the control range of the liquid crystal is expanded, allowing the liquid crystals in the liquid crystal layer 3 to be affected by the induction electrodes 31 and arranged close to the color resist 5 near the liquid crystal itself, thereby improving the light shielding effect and light output brightness.

[0044] The embodiments of the present application also provide a display device, which can be a foldable flexible display device or a non-foldable display device, and can be an ordinary display device or a VR display device. The display device can be used in electronic devices with display screens, such as mobile phones and computers. The display device includes a display panel as described in any of the above embodiments. Because the display device includes the display panel described in the above embodiments, it also has the structure and beneficial effects of the display panel. The derivation process of the specific structure and beneficial effects can be found in the above embodiments, which will not be repeated here.
