Display panel and display device

Abstract

The present application relates to a display panel and a display device. Through the telescopic adjustment of a second support column, in conjunction with information about the distance between the first support column and the first substrate, the position of the second support column can be adjusted to restore the distance between the first substrate and the first support column. This arrangement can restore the thickness between the first and second substrates, preventing the liquid crystal at the position of the first support column from flowing to the sides, causing the gap between the liquid crystal layer at the edge to increase. The present application effectively solves the problem in the prior art where the support column at the center of the display panel is squeezed for a long time, resulting in the support column not returning to its original height, causing the liquid crystal at the center of gravity to flow to the edge of the liquid crystal layer, thereby increasing the gap between the edge liquid crystal layer, lengthening the wavelength of light that can pass through, and causing the display to appear yellow.

Description

Technical Field

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

[0002] The working principle of the liquid crystal display panel is to inject liquid crystal between the array substrate and the color filter substrate, and apply a driving voltage to the two substrates to control the rotation of the liquid crystal molecules to determine the brightness of the sub-pixels. Different RGB sub-pixel brightness combinations form various colors, and different colors on different pixels are finally combined to form a colorful picture. Most liquid crystal displays are backlit liquid crystal displays, which mainly include liquid crystal display panels and backlight modules. The liquid crystal panel is mainly composed of an array substrate and a color filter substrate filled with liquid crystal, and sealed with a frame sealant. There are many film layers on the array substrate and the color filter substrate. The backlight source is a structure composed of a light source, an optical film, a frame sealant, etc. Its function is to provide a dedicated light source for the TFT-LCD.

[0003] like Figure 1 As shown in the prior art, during the press or slight drop test, the LCD panel often displays yellowing around its edges. This is because during the press or test, the center of the LCD panel is subjected to external force, and the support pillars in this area are compressed. After a long period of compression, they do not return to their original state, resulting in a lower height of the support pillars in this area and a smaller gap in the liquid crystal layer. However, the edges of the liquid crystal layer are supported by the cell and packaging structures, and the height of the support pillars is almost unaffected. The gap in the liquid crystal layer at the center becomes smaller, causing the liquid crystal to flow to the surrounding areas, thereby increasing the gap in the edge liquid crystal layer. When the gap in the edge liquid crystal layer increases, the glass transmittance increases, the wavelength of light allowed to pass becomes longer, and more red and green light increases, so the visual appearance will appear yellow. Summary of the Invention

[0004] The present application provides a display panel and a display device to solve the problem in the prior art that, due to the long-term squeezing of the support pillars at the center of the display panel, the support pillars fail to recover their original height, causing the liquid crystal at the center of gravity to flow to the edge of the liquid crystal layer, thereby causing the gap between the edge liquid crystal layers to become larger, the wavelength of the light that can pass through to become longer, and the display to appear yellow.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0028] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures.

Thus, the example term "below" can include both above and below orientations.

[0029] like Figures 2 to 4As shown, in the first aspect, an embodiment of the present application provides a display panel, including: a first substrate 10, a second substrate 20 and a detection component 30; a first support column 21 and a second support column 22 are provided on the side of the second substrate 20 facing the first substrate 10, and the second support column 22 can be extended and retracted in a direction close to or away from the first substrate 10; the detection component 30 is provided between the first support column 21 and the first substrate 10, and the detection component 30 is used to detect the distance information between the first substrate 10 and the first support column 21, and adjust the extension length of the second support column 22 according to the distance information.

[0030] By adjusting the retractable second support column 22 in conjunction with the distance information between the first support column 21 and the first substrate 10, the position of the second support column 22 can be adjusted to restore the distance between the first substrate 10 and the first support column 21. This arrangement can restore the thickness between the first substrate 10 and the second substrate 20, preventing the liquid crystal at the position of the first support column 21 from flowing to the sides, causing the gap between the liquid crystal layer at the edge to increase. This application effectively solves the problem in the prior art where the support column at the center of the display panel is squeezed for a long time, resulting in the support column not returning to its original height, causing the liquid crystal at the center of gravity to flow to the edge of the liquid crystal layer, thereby increasing the gap between the edge liquid crystal layer, lengthening the wavelength of light that can pass through, and causing the display to appear yellow.

[0031] It should be noted that the display surface in this embodiment can be applied to a thin-film transistor liquid crystal display (TFT-LCD), which is a mainstream display currently on the market and can be specifically applied to televisions, laptops, tablets, mobile phones, in-vehicle displays, and many other fields. The first substrate 10 can correspond to the array substrate of the liquid crystal display panel, and the second substrate 20 corresponds to the color filter substrate. Liquid crystal is injected between the array substrate and the color filter substrate, and a driving voltage is applied to the two substrates to control the rotation of the liquid crystal molecules to determine the brightness of the sub-pixels. Different RGB sub-pixel brightness combinations form various colors, and the different colors on different pixels are finally combined to form a colorful picture.

[0032] In the technical solution of this embodiment, the first support columns 21 and the second support columns 22 can be arranged alternately or in an alternating array. This ensures that when the first substrate 10 corresponding to the first support column 21 at a single position is deformed and not restored, it can be restored by the multiple second support columns 22 on its surrounding side. The second support columns 22 themselves have a certain elasticity, and will not directly hit the first substrate 10 when pressed, which may easily cause damage and leakage. After the second support columns 22 are compressed, elastic recovery can be achieved through the elasticity of the second support columns 22. When elastic recovery is achieved at multiple positions at the same time, the first substrate 10 can be reset, and the area corresponding to the first support column 21 will not be concave, causing the liquid crystal to spread around and then turn yellow.

[0033] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the first support column 21 is fixedly arranged, and the detection component 30 is a displacement sensor. The fixed arrangement of the first support column 21 is used to provide a detection reference for the detection component 30, so that the distance information between the first substrate 10 and the first support column 21 collected by the detection component 30 can be more accurate, thereby increasing the adjustment accuracy of the second support column 22 and achieving a better recovery effect. The detection component 30 is a displacement sensor, and can also collect the displacement distance of the first substrate 10 corresponding to the position of the first support column 21, so that the detection accuracy is higher. Specifically, the displacement sensor can be an infrared laser sensor, or other sensors that can characterize the distance between the first support column 21 and the corresponding position of the first substrate 10. It should be noted that the detected distance is the shortest straight-line distance between the first support column 21 and the first substrate 10.

[0034] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the detection component 30 includes a first electrode 31 and a second electrode 32. The first electrode 31 is arranged on the side of the first substrate 10 facing the second substrate 20, and the second electrode 32 is arranged on the end of the first support column 21 facing the first substrate 10. The first electrode 31 and the second electrode 32 form a capacitor structure. The first electrode 31 and the second electrode 32 are arranged in a manner to form a capacitor, and the displacement is detected by the distance between the first electrode 31 and the second electrode 32, that is, by the size of the capacitance. It should be noted that the first electrode 31 is specifically arranged on the insulating layer on the first substrate 10, and the insulating layer is arranged facing the second substrate 20.

[0035] Specifically, if Figures 2 to 4As shown, before the first substrate 10 is pressed, the distance between the first electrode 31 and the second electrode 32 is d1, and the capacitance formed between the two is a fixed value. At this time, the circuit connected by the capacitor is in a stable state; after the first substrate 10 is pressed, the distance between the first electrode 31 and the second electrode 32 is shortened to d2, that is, d2<d1. At this time, the capacitance of the capacitor changes, the dielectric constant ε of the capacitor remains unchanged, and the area S facing the capacitor remains unchanged. The capacitance determination formula is: C=εS / d. The only value that changes is the distance between the two electrodes, that is, the distance between the first electrode 31 and the second electrode 32 is shortened, and the capacitance increases. According to the capacitance calculation formula C=Q / U, it can be seen that when the voltage remains unchanged, the capacitance increases and the quantity Q increases. When the output value of the current is used as the detection signal, the larger the quantity Q, the larger the output current. The external control component can judge the compression amount of the panel according to the magnitude of the current, and then send an appropriate adjustment signal to the second support column 22 to make the panel recover.

[0036] like Figures 2 to 4As shown, in the technical solution of this embodiment, there are multiple first support columns 21, and multiple detection components 30 are provided corresponding to the first support columns 21. Specifically, each detection component 30 includes a first electrode 31 and a second electrode 32 provided corresponding to a certain first support column 21. The first electrode 31 provided in the detection component 30 is opposite to the second electrode 32 to form a capacitor structure. Multiple detection components 30 can form multiple capacitor structures. Such a setting makes the corresponding area between the first electrode 31 and the second electrode 32 more accurate. When the corresponding areas of the first electrode 31 and the second electrode 32 in a detection component 30 are misaligned, data analysis can be made based on the current corresponding to other detection components 30, and then adjustments can be made more targeted. On the one hand, such a setting makes the detection area more accurate and the control basis for the second support column 22 more accurate. It should be noted that the detection components 30 are provided with multiple corresponding to the first support columns 21, which can include the following optional implementation scenarios: Optionally, the detection components 30 can be provided in a one-to-one correspondence with the first support columns 21, that is, each position of the first support column 21 is provided with a detection component 30. In this implementation scenario, detection data can be obtained for the corresponding area of ​​each first support column 21, and sufficient data samples can be obtained for analysis; Optionally, the positions of some first support columns are provided with detection components 30, and the positions of other first support columns 21 are not provided with detection components 30. In this implementation scenario, some of the first support columns 21 can be selected according to the use needs of the display panel to set the detection components 30, and when the data analysis is satisfied, The number of detection components 30 can be reduced under the premise of the required number of data samples. For example, the detection components 30 can be set on the first support column 21 in the area with higher pressing frequency, or evenly set on part of the first support columns 21 in the panel area; optionally, any first support column 21 can also be correspondingly provided with multiple detection components 30. Taking the example of two detection components 30 being provided on a certain first support column 21, each detection component 30 includes a first electrode 31 and a second electrode 32 provided corresponding to the first support column 21, so that two second electrodes 32 are provided on the first support column 21, and two first electrodes 31 facing the above-mentioned two second electrodes 32 are provided on the first substrate 10 to form two capacitor structures.

[0037] like Figures 2 to 4As shown, in the technical solution of this embodiment, flexible electrodes 23 are provided on the surfaces of the first support column 21 and the second support column 22, and the flexible electrodes 23 are connected to the second substrate 20. The surfaces of the first support column 21 and the second support column 22 can be the side surfaces or the top surfaces facing the first substrate 10. The provision of the flexible electrodes 23 enables the flexible electrodes 23 to expand and contract in conjunction with the extended position during the recovery process after the second support column 22 is compressed. On the one hand, this prevents the flexible electrodes 23 from falling off the second substrate 20. On the other hand, it can wrap around the entire first support column 21 and the second support column 22, thereby isolating the liquid crystal from the support columns.

[0038] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the second support column 22 includes a support column body 221 and a deformable structure 222, which are sequentially arranged from the first substrate 10 to the second substrate 20. The end of the deformable structure 222 away from the support column body 221 is fixedly connected to the second substrate 20. The setting of the deformable structure 222 is used to enable the support column body 221 to actively expand and contract. On the one hand, such a setting can play a certain role in relieving force when compressed, avoiding excessive direct force when under pressure, which would cause direct crushing of the support column body 221. On the other hand, the deformable structure 222 can actively change the position of the support column body 221, playing an active recovery effect. Such a setting structure is compact and the effect is more intuitive.

[0039] like Figures 2 to 4 As shown, in the technical solution of this embodiment, the deformation structure 222 is made of magneto-deformable material, and a magnetic drive structure 223 is provided on the side of the deformation structure 222 away from the support column 221. Magneto-deformable material is a magnetic field responsive polymer composite material formed by embedding magnetic particles into a flexible polymer matrix. Under an external magnetic field, the magnetic particles or permanent magnets in the flexible matrix interact with the magnetic field to generate a torque and drive the flexible matrix to move, thereby deforming, shrinking, elongating and bending. Such a structural setting is simple to achieve active deformation, and the deformation ability can be achieved by controlling the magnetic field or by controlling the current of the magnetic field generating component to achieve the effect of the deformation structure 222. While the effect is intuitive, the structure is simple and compact, and the control is convenient. It should be noted that the flexible matrix material can be silicone rubber, natural rubber, polyurethane and polydimethylsiloxane (PDMS), etc., and the magnetic particles can be iron particles including carbonyl groups, etc.

[0040] like Figures 2 to 4As shown, in the technical solution of this embodiment, the deformable structure 222 is located within the area enclosed by the flexible electrode 23. This arrangement allows the deformable structure 222 to be completely enclosed within the space enclosed by the flexible electrode 23, the support column 221, and the magnetic drive structure 223. This arrangement prevents leakage of the magnetostrictive material and prevents contact between the magnetostrictive material and the plate portion of the second substrate 20, which could cause color changes in the color filter substrate. It should be noted that the magnetic drive structure 223 can be fixedly disposed within the color filter substrate by embedding or other means, and electrically connected to the external control component via the printed circuit board of the color filter substrate.

[0041] In an alternative embodiment, the deformable structure 222 can also be made of an electrodeformable material. A drive electrode is provided on the side of the deformable structure 222 away from the support column 221. The deformable structure 222 formed of the electrodeformable material can extend or contract under the action of the voltage or current of the drive electrode, thereby causing the second support column to deform accordingly. Similarly, the deformable structure 222 formed of the electrodeformable material is preferably located within the area surrounded by the flexible electrode 23, so that the deformable structure 222 is completely enclosed within the space enclosed by the flexible electrode 23, the support column 221, and the magnetic drive structure 223. This prevents leakage of the electrodeformable material and avoids contact between the electrodeformable material and the plate portion of the second substrate 20, which could cause color changes in the color filter substrate. The electrodeformable material uses a more direct deformation method to achieve the deformation setting of the deformable structure 222. The control of the deformable structure 222 is achieved by controlling the voltage or current. This configuration is more intuitive and has the same structural applicability. Specific electrodeformable materials can be dielectric elastomers such as silicone rubber and dielectric elastomers such as acrylic.

[0042] According to some embodiments of the present application, a first electrode 31 is provided on the insulating layer on the side of the first substrate 10 facing the second substrate 20, and the first electrode 31 is only provided opposite to the first support column 21 and is distributed at intervals, that is, the first electrode 31 is not provided at the relative position of the second support column 22; the second electrode 32 is provided on the top of the first support column 21, and is connected through the flexible electrode 23 covering the surface of the second support column 22 and the side of the first support column 21; wherein the first electrode 31 and the second electrode 32 can be made of a transparent conductive material such as indium tin oxide, and the flexible electrode 23 can be a carbon grease electrode, which has good conductivity and can maintain Prove its toughness and mechanical properties; at the same time, a groove is set in the flat layer of the color filter substrate, that is, the second substrate 20, and a magnetic driving structure 223 or a driving electrode is fixedly set inside the groove. The magnetic driving structure 223 is arranged opposite to the deformation structure 222 set by the magneto-deformable material under the second support column 22, that is, the opening and closing of the magnetic driving structure 223 causes the deformation structure 222 to expand and contract to control the height of the second support column 22; the driving electrode is arranged opposite to the deformation structure 222 set by the electro-deformable material under the second support column 22, that is, the adjustment of the voltage or current parameters of the driving electrode causes the deformation structure 222 to expand and contract to control the height of the second support column 22.

[0043] Magnetodeformable materials are magnetic field-responsive polymer composites formed by embedding magnetic particles into a polymer matrix. Under an external magnetic field, the magnetic particles or permanent magnets in the flexible polymer matrix interact with the magnetic field, generating a torque that drives the flexible matrix to move, causing deformation, contraction, elongation, and bending. The matrix materials mainly include silicone rubber, natural rubber, polyurethane, and polydimethylsiloxane (PDMS), and the magnetic particles include carbonyl iron particles. The magnetodeformable unit can also be replaced by an electrodeformable unit, where the corresponding magnetic drive unit is replaced by a drive electrode, and the electrodeformable unit can be a silicone rubber or acrylic dielectric elastomer.

[0044] Taking the magnetostrictive deformation unit as an example, before the panel is compressed, the distance between the first electrode 31 and the second electrode 32 is d1, and the capacitance formed between the two electrodes is fixed. After compression, the distance between the first and second electrodes decreases to d2. Before and after compression, the dielectric constant ε remains unchanged, and the area S opposite the capacitor also remains unchanged. According to the capacitance determination formula: C = εS / d, when the distance between the two electrodes changes from d1 to d2, the capacitance increases. Furthermore, according to the capacitance calculation formula: C = Q / U, when the voltage U between the first and second electrodes remains unchanged, as the capacitance increases, the quantity Q increases. When the second electrode, acting as a displacement sensor, outputs a current as a detection signal, the greater the quantity Q, the greater the output current. The external control module can determine the amount of compression of the panel based on the magnitude of the current. Based on the magnitude of the compression, the external control module applies a corresponding current to activate the magnetic drive unit. The magnetic drive unit then operates, causing the magnetostrictive deformation unit to extend, driving the second support column 22 to return to its initial position, thereby maintaining the stability of the box thickness.

[0045] In the embodiments of the present application, a first electrode 31 and a second electrode 32 are respectively disposed on the insulating layer of the first substrate 10 opposite the first support column 21 and on the surface of the first support column 21 within the liquid crystal cell. A capacitor is formed between the two electrodes. When the liquid crystal panel is subjected to force, the cell thickness changes, which in turn causes the distance between the first electrode 31 and the second electrode 32 to change. Consequently, the capacitance formed between the two electrodes changes. When the second electrode 32 functions as a displacement sensor and outputs a current as a detection signal, the magnitude of the current increases with the increase in capacitance. An external sensor receives the electrical signal from the second electrode 32, determines the change in cell thickness, and then adjusts the operating parameters of the magnetic drive structure 223 or the drive electrode. The magnetic drive structure 223 then operates to cause the deformable structure 222 made of magnetostrictive material to extend, or the drive electrode operates to cause the deformable structure 222 made of electrostrictive material to extend, thereby causing the second support column 22 to return to its initial position to maintain a stable cell thickness. This structure can solve the problem of uneven cell thickness and thus Mura caused by the inability of support columns to recover during the pressure process of the LCD panel. It is of great significance for improving the yield of LCD display panels, resolving customer complaints and improving product reputation.

[0046] In a second aspect, embodiments of the present application provide a display device comprising a display panel as provided in the above embodiments. After testing and pressing, a display device employing the above display panel does not suffer from the inability to recover due to the transitional deformation of support pillars within the liquid crystal layer, which would cause liquid crystal to flow outward toward the periphery, thereby increasing the amount of liquid crystal on the periphery and thereby increasing light transmittance, leading to yellowing of the display area. Such a display device provides enhanced display quality and practicality, and users do not need to worry about yellowing.
