[0002] Liquid Crystal Displays (LCDs) have rapidly gained market and consumer acceptance and widespread use due to their thinness, low power consumption, and low radiation. However, during the manufacturing process, LCD panels can exhibit uneven brightness (mura) in the displayed image due to factors such as materials and manufacturing processes. Currently, the market typically employs external planar optical compensation (Demura) technology to compensate for this unevenness, improving the uniformity of the image display and enabling the panel to display a normal flat image.
[0003] In practical applications, when a display panel is used as a curved display screen, the panel will develop a curved surface mura due to the bending. Since the position and shape of the curved surface mura are fixed, the curved surface mura caused by the bending of the display panel is generally eliminated by performing planar compensation and curved surface compensation through superimposing the display panel.
[0004] However, when the display panel is overlaid with planar compensation and curved surface compensation, if the display panel that can be used for curved display is then used for planar display, the sides of the flat display will appear white, which means that the display panel cannot meet the display requirements of both curved and flat display at the same time.

[0032] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this application.
[0033] The following descriptions of the embodiments are based on the accompanying illustrations and are used to illustrate specific embodiments in which this application can be implemented. The component designations used herein, such as "first," "second," etc., are merely for distinguishing the described objects and do not have any sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages). Directional terms used in this application, such as "up," "down," "front," "rear," "left," "right," "inner," "outer," "side," etc., are merely for reference to the accompanying drawings. Therefore, the use of directional terms is for better and clearer explanation and understanding of this application, and does not indicate or imply that the referred device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application.
[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. It should be noted that the terms "step 1," "step 2," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific sequence.
[0035] In the field of display technology, the generation of mura on display panels is caused by a variety of factors, such as the color filter (CF) manufacturing process, the thin film transistor (TFT) manufacturing process, the LCD module (LCM) manufacturing process, and the bending of the display panel. Display panels can be divided into flat display panels and curved display panels according to their display method. Flat display panels are used for flat displays, while curved display panels are used for curved displays. The main difference between flat and curved display panels in terms of mura generation lies in the fact that curved display panels are assembled with curved backlight structures, and the bending of curved display panels will generate some mura, while flat display panels do not need to consider the issue of mura caused by the bending of the display panel.
[0036] To better illustrate and understand the technical solution of this application, and to clearly distinguish between mura caused by bending of the display panel and mura caused by manufacturing processes or other reasons, this application refers to brightness unevenness (mura) caused by factors such as materials and manufacturing processes during production as the first mura, and the mura caused by bending of the display panel as the second mura. Accordingly, the data for external optical compensation used to reduce or eliminate the first mura is referred to as planar compensation data data1, and the data for external optical compensation used to reduce or eliminate the second mura is referred to as curved surface compensation data data2.
[0037] Please refer to the following: Figures 1 to 4 , Figure 1 This is a schematic diagram of a planar display panel with planar compensation disclosed in an embodiment of this application. Figure 2 for Figure 1 The diagram shows a curved display panel. Figure 3 This is a schematic diagram of a curved surface display panel with superimposed planar compensation and curved surface compensation disclosed in an embodiment of this application. Figure 4 for Figure 3 The diagram shows a planar display of the display panel.
[0038] like Figure 1 As shown, after applying Demura technology to the display panel 100 for planar compensation, the brightness unevenness (Mura) caused by factors such as materials and manufacturing processes during production is eliminated, resulting in a uniform display on the display panel 100. Figure 2 As shown, the display panel 100 has undergone planar compensation, eliminating brightness unevenness (Mura) caused by factors such as materials and manufacturing processes during production. However, when the display panel 100 is used for curved display, curved Mura 200 will reappear due to the curvature of the display panel 100. Figure 3 As shown, the display panel 100 undergoes superimposed planar compensation and curved surface compensation, that is, in Figure 1 Based on planar compensation, surface compensation further eliminates the Mura200 curvature caused by the bending of the display panel. For example... Figure 4 As shown, when the display panel 100, after superimposed planar compensation and curved surface compensation, exhibits a whitening phenomenon on both sides during planar display.
[0039] Please see Figure 5 , Figure 5 This is a schematic diagram of the circuit structure of a driving circuit disclosed in an embodiment of this application. Figure 5As shown, this application embodiment provides a driving circuit 300. The driving circuit 300 enables the display panel 100 to form two architectures to match different types of display devices 1000. That is, the driving circuit 300 can be used to selectively perform planar compensation on the display panel 100, or to superimpose planar compensation and curved surface compensation. Therefore, the driving circuit 300 can solve the problem of whitening on both sides of the screen when the display panel 100 is displayed in a planar manner, and the problem of poor compatibility caused by the incompatibility between planar and curved surface displays.
[0040] In this embodiment, the driving circuit 300 is used to selectively compensate the display panel 100. The driving circuit 300 may include at least a timing controller 20, a control unit 30, and a memory chip 40. The timing controller 20 is electrically connected to both the memory chip 40 and the control unit 30, and the control unit 30 is electrically connected to the display panel 100.
[0041] The storage chip 40 stores planar compensation data data1 and curved surface compensation data data2. The timing controller 20 receives the compensation control signal transmitted by the control unit 30, and reads the planar compensation data data1 according to the compensation control signal and transmits it to the control unit 30; alternatively, the timing controller 20 reads both the curved surface compensation data data2 and the planar compensation data data1 according to the compensation control signal and transmits them to the control unit 30.
[0042] The control unit 30 receives and performs corresponding display compensation on the display panel 100 based on the planar compensation data data1, or based on the planar compensation data data1 and the curved surface compensation data data2. Specifically, when the control unit 30 receives the planar compensation data data1, the control unit 30 performs a first type of display compensation on the display panel based on the planar compensation data data1, i.e., planar display compensation. When the control unit 30 simultaneously receives the planar compensation data data1 and the curved surface compensation data data2, the control unit 30 performs a second type of display compensation on the display panel based on the planar compensation data data1 and the curved surface compensation data data2, i.e., curved surface display compensation.
[0043] In this embodiment, the curvature of the display panel 100 for curved display can be R800, R1000, R1500, R1800, R3000, or other values, and this application does not impose specific limitations on this. It should be noted that R1000 indicates that the curvature of the display panel 100 when displaying a curved surface is an arc with a radius of 1 meter, and other curvatures follow the same principle.
[0044] In the embodiments of this application, the control unit 30 may be a system on chip (SoC) or other control devices, and this application does not impose any specific restrictions on it.
[0045] In this embodiment, the driving circuit 300 further includes a circuit board 60, and the memory chip 40 is fixed to and electrically connected to the circuit board 60. The memory chip 40 is electrically connected to the timing controller 20 through the circuit board 60, and the memory chip 40 can transmit signals with the timing controller 20. That is, the memory chip 40 is electrically connected to the circuit board 60, and the timing controller 20 is electrically connected to the circuit board 60. Further, the memory chip 40 is electrically connected to the timing controller 20.
[0046] In this embodiment of the application, the timing controller 20 receives the compensation control signal from the control unit 30 and reads the corresponding compensation data from the storage chip 40 according to the potential of the compensation control signal.
[0047] Specifically, when the compensation control signal is at the first potential, the timing controller 20 reads the planar compensation data data1 from the storage chip 40 and transmits the planar compensation data data1 to the control unit 30. When the compensation control signal is at the second potential, the timing controller 20 simultaneously reads the planar compensation data data1 and the curved surface compensation data data2 from the storage chip 40 and transmits the planar compensation data data1 and the curved surface compensation data data2 to the control unit 30.
[0048] In the embodiments of this application, the first potential can be a high potential and the second potential can be a low potential; this application does not impose specific limitations on this.
[0049] In specific embodiments of this application, the high potential can be 3.3 volts (V) and the low potential can be 0 volts (V), and this application does not impose specific limitations on this.
[0050] In a specific embodiment of this application, the circuit board 60 can be an x-board circuit board, as long as it enables the memory chip 40 to be electrically connected to the timing controller 20, this application does not impose any specific restrictions on this.
[0051] In specific embodiments of this application, the storage chip 40 can be a Flash storage chip (Flash EEPROM Memory), also known as flash memory. This application does not impose specific limitations as long as the compensation data can be stored / written in the storage chip 40 and the timing controller 20 can read the data information stored in the storage chip 40.
[0052] In this embodiment, the drive circuit 300 may further include a connector 50 for electrically connecting the timing controller 20 and the control unit 30. The connector 50 may define an enable pin (e.g., Mura_en), through which the compensation control signal sent by the control unit 30 is transmitted to the timing controller 20.
[0053] Please refer to the following: Figure 6 , Figure 6 This is a schematic diagram of the structure of a memory chip in a driving circuit disclosed in an embodiment of this application. In this embodiment, the memory chip 40 includes a first storage space 12 and a second storage space 14. The first storage space 12 is used to store the planar compensation data data1, and the second storage space 14 is used to store the planar compensation data data1 and the curved surface compensation data data2.
[0054] Specifically, when the compensation control signal is at the first potential (i.e., high potential), the timing controller 20 reads the compensation data, i.e., the planar compensation data data1, from the first storage space 12.
[0055] When the compensation control signal is at the second potential (i.e., low potential), the timing controller 20 reads the compensation data from the second storage space 14, namely the planar compensation data data1 and the curved surface compensation data data2.
[0056] In a specific embodiment of this application, the display panel 100 is tested using a preset scheme to obtain the planar compensation data data1 and the curved surface compensation data data2. The planar compensation data data1 is written to the first storage space 12, and both the planar compensation data data1 and the curved surface compensation data data2 are simultaneously written to the second storage space 14. The planar compensation data data1 and the curved surface compensation data data2 may include parameters such as luminance compensation values, which are not specifically limited in this application.
[0057] It is understood that the preset scheme may refer to a scheme that uses external optical compensation (Demura) technology to compensate for the display panel.
[0058] In summary, in the driving circuit 300 of this application, by setting the storage chip 40, compensation data for curved and flat displays of the display panel 100 are stored in the corresponding storage spaces of the storage chip 40. Based on the display type of the display device 1000, the driving circuit 300 can selectively acquire the corresponding compensation data and perform corresponding flat display compensation and curved display compensation on the display panel 100, so that the display panel 100 can form two architectures to match different types of display devices 1000. Therefore, the driving circuit 300 can solve the problem of whitening on both sides of the screen when the display panel 100 is in flat display mode, and the problem of poor compatibility caused by the incompatibility between flat and curved displays.
[0059] Please refer to the following: Figure 7 , Figure 7 This is a flowchart illustrating a driving method disclosed in an embodiment of this application. Based on the same inventive concept, this application also provides a driving method for a display panel 100. Figure 7 As shown, the driving method may include at least:
[0060] Step S10: The control unit 30 sends a corresponding compensation control signal to the timing controller 20 according to the screen display type of the display panel 100.
[0061] In a specific embodiment of this application, the display type of the display panel 100 includes planar display and curved display. When the display panel 100 performs a planar display, the control unit 30 sends a compensation control signal at a first potential to the timing controller 20. When the display panel 100 performs a curved display, the control unit 30 sends a compensation control signal at a second potential to the timing controller 20.
[0062] In this embodiment, depending on whether the display panel 100 is a curved or flat display, the control unit 30 can be preset to transmit a compensation control signal at a first potential (i.e., high potential) or a second potential (i.e., low potential). Specifically, when the display panel 100 is a flat display, the control unit 30 is preset to output a compensation control signal at the first potential. When the display panel 100 is a curved display, the control unit 30 is preset to output a compensation control signal at the second potential.
[0063] Step S20: The timing controller 20 reads compensation data from the storage chip 40 according to the compensation control signal and transmits the compensation data to the control unit 30.
[0064] In this embodiment, when the compensation control signal received by the timing controller 20 is at a first potential, the timing controller 20 reads the planar compensation data data1. When the compensation control signal received by the timing controller 20 is at a second potential, the timing controller 20 simultaneously reads the planar compensation data data1 and the curved surface compensation data data2.
[0065] In a specific embodiment of this application, when the compensation control signal received by the timing controller 20 is at the first potential, the timing controller 20 reads the plane compensation data data1 from the first storage space 12 of the storage chip 40 and transmits the plane compensation data data1 to the control unit 30.
[0066] When the compensation control signal received by the timing controller 20 is at the second potential, the timing controller 20 simultaneously reads planar compensation data data1 and curved surface compensation data data2 from the second storage space 14 of the storage chip 40, and transmits the planar compensation data data1 and curved surface compensation data2 to the control unit 30.
[0067] Step S30: Receive the compensation data through the control unit 30 and perform planar display compensation and curved surface display compensation on the display panel 100 according to the compensation data.
[0068] In this embodiment of the application, display compensation for the display panel 100 is achieved through Demura technology.
[0069] In summary, in the driving method of the display panel of this application, by setting the storage chip 40, compensation data for curved display and flat display of the display panel 100 are stored in the corresponding storage space of the storage chip 40. According to the display type of the display device 1000, the driving circuit 300 can selectively obtain the corresponding compensation data and perform corresponding flat display compensation and curved display compensation on the display panel 100, so that the display panel 100 can form two architectures to match different types of display devices 1000. Therefore, the driving method can solve the problem of whitening on both sides of the screen when the display panel 100 is in flat display, and the problem of poor compatibility caused by the incompatibility between flat display and curved display.

The driving circuit 300 is electrically connected to the display panel 100. After display compensation by the driving circuit 300, the display panel 100 emits corresponding light according to the image data to be displayed to perform image display.

Based on the same concept, this application also discloses a display device 1000, which may include at least the display module 10, support frame 70, and power module 80 described above. The display module 10 is fixed to the support frame 70, and the power module 80 is disposed on the back of the display module 10, i.e., the non-display surface of the display module 10, i.e., the side of the display module 10 facing away from the user. The display module 10 is used to display images, and the power module 80 is electrically connected to the display module 10 to provide power voltage for image display. The support frame 70 provides support and protection for the display module 10 and the power module 80.
[0073] It is understood that the display module 10 also has a display surface disposed opposite to the non-display surface, i.e., the front of the display module 10, that is, the side of the display module 10 facing the user. The display surface is used to face the user using the display device 1000 to display images.
[0074] In summary, in the display module 10 and display device 1000 of this application, by setting the storage chip 40, compensation data for curved and flat displays of the display panel 100 are stored in the corresponding storage spaces of the storage chip 40. Based on the display type of the display device 1000, the driving circuit 300 can selectively acquire the corresponding compensation data and perform corresponding flat display compensation and curved display compensation on the display panel 100, so that the display panel 100 can form two architectures to match different types of display devices 1000. Therefore, the display module and display device of this application can solve the problem of whitening on both sides of the screen when the display panel 100 is in flat display mode, and the problem of poor compatibility caused by the incompatibility between flat and curved displays.
