Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display device with an integrated flash register. Background Technology

[0002] Active-matrix organic light-emitting diode (AMOLED / Micro OLED) displays, due to their current-driven characteristics, require high uniformity in the manufacturing process. Especially when displaying low brightness or low grayscale, differences in driving current between pixels can easily lead to uneven brightness and color, resulting in a display inhomogeneity (mura). This phenomenon is particularly noticeable when displaying large areas of solid color images, severely affecting the visual experience.

[0003] Existing improvement solutions typically employ external flash memory (Flash IC) to store the brightness compensation data for each pixel, which is then read by the driver chip for pixel-by-pixel compensation upon screen startup. Furthermore, existing AMOLED / MICRO OLED modules utilize driver ICs that include touch and display drivers for the LCD portion and De-mura drivers with speckle reduction capabilities for the AMOLED / MICRO OLED portion. Therefore, two flash memories are still required, leading to increased component count, layout space requirements, and overall cost. Summary of the Invention

[0004] To address the aforementioned challenges, this invention provides a display device with an integrated flash register. By integrating the touch and display driver IC and the De-mura driver IC into a single integrated driver chip, and by integrating the two flash registers respectively configured in the touch and display driver IC and the De-mura driver IC into one, the number of flash registers used is reduced and the manufacturing cost is lowered.

[0005] To achieve the above objectives, the present invention provides a display device with an integrated flash register, including a display screen, an integrated driver chip, a microcontroller chip, and an integrated flash register; An integrated driver chip is used to control the display screen to perform touch and display functions as well as spot removal functions; A microcontroller chip is electrically connected to the integrated driver chip and is used to control the integrated driver chip; An integrated flash register is connected to the integrated driver chip and the microcontroller chip; The microcontroller chip writes the driver files required by the integrated driver chip into the integrated flash register, which is used to store the driver files required by the integrated driver chip.

[0006] Preferably, the integrated flash register includes a first storage area and a second storage area, which are used to store the driver files for the touch and display functions and the driver files for the spot removal function, respectively.

[0007] Preferably, the capacity of the first storage area is not less than 32MB, and the capacity of the second storage area is not less than 32KB.

[0008] Preferably, the storage capacity of the integrated flash register is any one of 32MB+32KB, 64MB+32KB, and 128MB+32KB.

[0009] Preferably, the integrated flash register is a NOR flash register.

[0010] Preferably, the integrated flash register and the display screen each have a serial peripheral interface.

[0011] Preferably, the serial peripheral interface of the integrated flash register and the serial peripheral interface of the display are interconnected via flexible printed circuitry.

[0012] Preferably, the display device is either a liquid crystal display or an active matrix organic light-emitting device.

[0013] Therefore, the present invention adopts a display device with an integrated flash register, which integrates two flash registers respectively configured in the touch and display driver chip and the speckle removal driver IC into one integrated flash register, which can save the number of flash registers used, optimize the space used in the display device, and reduce the manufacturing cost.

Terms such as "inner," "outer," "upper," and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In this invention, unless otherwise explicitly specified and limited, the term "attached" and similar terms should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements or the interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] Example 1: A display device with an integrated flash register, such as Figure 1 As shown, it includes a display screen 1, an integrated driver chip 2, a microcontroller chip 3, and an integrated flash register 4; An integrated driver chip 1 is used to control the display screen 1 to perform touch and display functions as well as spot removal functions; The microcontroller chip 2 is electrically connected to the integrated driver chip 1 and is used to control the integrated driver chip 1. The integrated flash register 4 is connected to the integrated driver chip 1 and the microcontroller chip 2; The microcontroller chip 2 writes the driver file required by the integrated driver chip 1 into the integrated flash register 4, which is used to store the driver file required by the integrated driver chip 1.

[0021] The display screen 1 also includes an operable area 5 and an integrated driver chip 1 and a microcontroller chip 2 that are electrically connected to each other; The integrated flash register 4 is a NOR flash register.

[0022] The integrated flash register 4 and the display screen 1 each have a serial peripheral interface 6, and the integrated flash register 4 and the display screen 1 communicate synchronously using the serial peripheral interface bus 6.

[0023] The serial peripheral interface of the integrated flash register and the serial peripheral interface of the display are interconnected via flexible printed circuitry.

[0024] Specifically, a flexible printed circuit board is used to connect to the integrated flash register 4 and the serial peripheral interface 6 of the display screen 1 respectively, so that the integrated flash register 4 and the display screen 1 can communicate with each other through the flexible printed circuit board and the communication protocol of the serial peripheral interface 6.

[0025] The display device is either a liquid crystal display or an active matrix organic light-emitting device.

[0026] The integrated flash register 4 includes a first storage area and a second storage area, which are used to store the driver files for the touch and display functions and the driver files for the spot removal function, respectively.

[0027] The capacity of the first storage area is not less than 32MB, and the capacity of the second storage area is not less than 32KB.

[0028] Specifically, this application integrates the touch and display driver chip and the speckle removal driver chip into a single integrated driver chip 2. Since the two driver chips are integrated into one, the required external flash register can also be integrated into one. The capacity of the integrated flash register 4 depends on the size of the driver file required by the integrated driver chip 2 to perform the speckle removal function. For example, the driver file required by the integrated driver chip 2 to perform the speckle removal function and stored in the integrated flash register 4 may be several tens of MB, while the driver file required by the integrated driver chip 2 to perform the touch and display functions may only be several tens of KB. Since the driver file required for the touch and display functions and stored in the integrated flash register 4 may only be several tens of KB, the required capacity space is only a small portion. Moreover, there is still space available after storing the speckle removal function driver file, so there is no need to configure an additional flash register. The capacity of the integrated flash register 4 can be designed as 32MB+32KB, 64MB+32KB or 128MB+32KB, where 32MB, 64MB and 128MB are used to store the driver files for the spot removal function, while 32KB is used to store the driver files for the touch and display functions.

[0029] Therefore, the present invention adopts a display device with an integrated flash register. By integrating two flash registers respectively configured in the touch and display driver chip and the speckle removal driver IC into one integrated flash register, the number of flash registers used can be reduced, the space used in the display device is more optimized, and the manufacturing cost can be reduced.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
