Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to an aging compensation method and device for display panels, as well as a display device. Background Technology

[0002] With the widespread application of Active-Matrix Organic Light-Emitting Diode (AMOLED) display technology in mobile devices, the issue of screen burn-in has become increasingly prominent. To address this problem, the industry commonly employs Dopant Blocking Injection (DBI) technology.

[0003] Traditional DBI (Display Driver Integration) technology is typically implemented within the display driver IC (DDI). This implementation requires the DDI to integrate a static random-access memory (SRAM) unit to store aging statistics for each pixel or pixel region. However, to achieve pixel-level compensation, the amount of aging statistics data to be stored would be enormous, which is unacceptable for area- and cost-sensitive DDIs. Therefore, the current common approach is to use pixel block averaging (e.g., 4x4, 8x8 pixels) to reduce the amount of data, but this method leads to a decrease in compensation effectiveness and fails to achieve accurate aging compensation.

[0004] Therefore, a new aging compensation method for display panels needs to be proposed to solve the above problems. Summary of the Invention

[0014] According to a second aspect of the present invention, an aging compensation device for a display panel is provided, comprising an application processor configured to receive original image data to be displayed, perform sub-pixel rendering on the original image data to obtain first image data, and embed aging compensation data into the first image data to obtain serial display data; and a display driver chip configured to receive the serial display data, separate the serial display data to obtain the aging compensation data and the first image data, and generate second image data based on the aging compensation data and the first image data to drive the display panel to emit light, wherein the aging compensation data includes current aging statistics data or first aging compensation data.

[0017] Optionally, the application processor further includes a compression encoding unit configured to compress the aging compensation data; the display driver chip further includes a compression decoding unit configured to decompress the compressed aging compensation data.

[0018] According to a third aspect of the present invention, a display device is provided, including the aging compensation device as described above; and a display panel configured to emit light under the drive of the second image data.

[0019] The present invention provides an aging compensation method, aging compensation device, and display device for display panels. At the application processor level, aging compensation data is embedded into first image data obtained through sub-pixel rendering to obtain serial display data. This serial display data is then transmitted to a display driver chip to perform aging compensation on the display panel. Since the first image data and aging compensation data arrive at the display driver chip simultaneously, aging compensation data can be transmitted on demand. Therefore, the display driver chip does not need to set up a static random access memory unit to pre-store the aging compensation data, reducing the area and power consumption of the display driver chip.

[0022] In a preferred embodiment, the display driver chip calculates the second aging compensation data by collecting environmental parameters (such as temperature) in real time, so that the compensation amount can be dynamically adjusted according to environmental changes, avoiding overcompensation or undercompensation caused by changes in environmental factors, and further improving the authenticity and reliability of the compensation effect.

[0032] Various embodiments of the invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements or modules are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0033] It should be understood that, in the following description, "circuit" may include single or combined hardware circuits, programmable circuits, state machine circuits, and / or elements capable of storing instructions executed by the programmable circuit. When an element or circuit is said to be "connected" to another element or "connected" between two nodes, it may be directly coupled or connected to the other element, or there may be intermediate elements; the connection between elements may be physical, logical, or a combination thereof. Conversely, when an element is said to be "directly coupled to" or "directly connected" to another element, it means that there are no intermediate elements between them.

[0034] Furthermore, certain terms are used in this patent specification and claims to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This patent specification and claims do not distinguish components based on differences in name, but rather on differences in function.

[0035] Furthermore, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] In existing technologies, to improve visual display resolution, the application processor (AP) performs subpixel rendering on the original RGB data format image data to obtain the first image data in RGBG data format. Compared to the original image data, the amount of data in the first image data is reduced by one-third. Therefore, compared to display devices that do not use subpixel rendering technology, display devices using subpixel rendering technology can save one-third of the bandwidth when the application processor transmits display data with the display driver chip. Here, R represents red subpixels, G represents green subpixels, and B represents blue subpixels.

[0037] Figure 1 A flowchart illustrating an aging compensation method for a display panel according to an embodiment of the present invention is shown.

[0038] See Figure 1 The aging compensation method for display panels provided in this embodiment of the invention includes steps S01-S04.

[0039] In step S01, the application processor receives the original image data to be displayed and performs sub-pixel rendering on the original image data to obtain the first image data.

[0040] The original image data includes multiple pixel packets corresponding one-to-one with each pixel unit of the display panel, and each pixel packet has RGB sub-pixel values. The first image data includes a first pixel packet with RG sub-pixel values ​​and a second pixel packet with BG sub-pixel values, with the first and second pixel packets arranged alternately, wherein each pixel unit corresponds to one pixel packet.

[0041] In step S02, the aging compensation data is embedded into the first image data by the application processor to obtain serial display data.

[0042] In the serial display data, the first image data and aging compensation data are arranged alternately.

[0043] The aging compensation data includes current aging statistics or first aging compensation data.

[0044] Step S02 includes the application processor updating the aging statistics of the display panel based on the aging compensation data obtained from the storage unit and the first image data to be displayed. The aging statistics obtained from the last update are the current aging statistics.

[0045] When the aging compensation data includes the current aging statistics, step S02 further includes: encapsulating the current aging statistics with the first image data to obtain serial display data.

[0046] When the aging compensation data includes the first aging compensation data, step S02 further includes: the application processor calculates the first aging compensation data based on the current aging statistics and the preset aging curve; and encapsulates the first aging compensation data with the first image data to obtain serial display data.

[0047] In step S03, serial display data is received through the display driver chip, and the serial display data is separated to obtain aging compensation data and first image data.

[0048] In step S04, the display driver chip generates second image data based on aging compensation data and first image data to drive the display panel to emit light.

[0049] When the aging compensation data includes current aging statistics, step S04 includes calculating first aging compensation data based on the current aging statistics and a preset aging curve; and generating second image data based on the first aging compensation data and the first image data.

[0050] When the aging compensation data includes first aging compensation data, step S04 includes generating second image data based on the first aging compensation data and the first image data.

[0051] The process of generating second image data based on first aging compensation data and first image data includes the display driver chip calculating the second aging compensation data based on the first aging compensation data, the first image data, and environmental parameters, and then superimposing the first image data and the second aging compensation data to obtain the second image data. For example, environmental parameters include temperature, voltage in decibels (dBV), and frequency gain.

[0052] Furthermore, the ratio between the number of sub-pixel values ​​in the first image data and the aging compensation values ​​in the aging compensation data is a preset ratio.

[0053] For example, the preset ratio is 2:1. In this case, two adjacent sub-pixels of the same color share a single aging compensation value. At a preset ratio of 2:1, the amount of serial display data is the same as the amount of original image data; that is, the bandwidth for transmitting serial display data is the same as the bandwidth for transmitting original image data in existing technologies. Therefore, no increase in bandwidth is required to transmit serial display data.

[0054] The serial display data consists of multiple data packets, each containing multiple sub-data packets. The aging compensation value in each data packet corresponds to its sub-pixel value. Each sub-data packet contains a pixel packet and an aging compensation value.

[0055] Figure 2 A schematic diagram of the arrangement of serial display data according to a first embodiment of the present invention is shown.

[0056] See Figure 2 Each data packet has four sub-data packets, with the first pixel packet and the second pixel packet arranged alternately in a 1×4 pattern. Specifically, the first sub-data packet contains sub-pixel values ​​R1, G1, and an aging compensation value CV1; the second sub-data packet contains sub-pixel values ​​B2, G2, and an aging compensation value CV2; the third sub-data packet contains sub-pixel values ​​R3, G3, and an aging compensation value CV3; and the fourth sub-data packet contains sub-pixel values ​​B4, G4, and an aging compensation value CV4.

[0057] The mapping relationship between sub-pixel values ​​and aging compensation values ​​is as follows: sub-pixel values ​​G1 and G2 share the aging compensation value CV1, sub-pixel values ​​R1 and R3 share the aging compensation value CV2, sub-pixel values ​​G3 and G4 share the aging compensation value CV3, and sub-pixel values ​​B2 and B4 share the aging compensation value CV4.

[0058] Understandable, Figure 2 The mapping relationship between sub-pixel values ​​and aging compensation values ​​is merely exemplary. In other embodiments of the present invention, other mapping relationships may also be used between sub-pixel values ​​and aging compensation values.

[0059] Figure 3 A schematic diagram of the arrangement of serial display data according to a second embodiment of the present invention is shown.

[0060] See Figure 3In the second embodiment of this application, each data packet has four sub-data packets, and the sub-data packets containing the first pixel packet and the second pixel packet are arranged alternately in a 2×2 manner. Specifically, the first sub-data packet in the first row has sub-pixel values ​​R1, G1, and an aging compensation value CV1, and the second sub-data packet has sub-pixel values ​​B2, G2, and an aging compensation value CV2. The first sub-data packet in the second row has sub-pixel values ​​B3, G3, and an aging compensation value CV3, and the second sub-data packet has sub-pixel values ​​R4, G4, and an aging compensation value CV4.

[0061] The mapping relationship between sub-pixel values ​​and aging compensation values ​​is as follows: sub-pixel values ​​R1 and R4 share the aging compensation value CV1, sub-pixel values ​​G1 and G3 share the aging compensation value CV2, sub-pixel values ​​B2 and B3 share the aging compensation value CV3, and sub-pixel values ​​G2 and G4 share the aging compensation value CV4.

[0062] Understandable, Figure 3 The mapping relationship between sub-pixel values ​​and aging compensation values ​​is merely exemplary. In other embodiments of the present invention, other mapping relationships may also be used between sub-pixels and aging compensation values.

[0063] It is understood that the method of embedding aging compensation data into the first image data in this application is not limited to the above methods, and this application does not impose specific limitations on it. For example, two aging compensation values ​​can be embedded sequentially after every two pixel packets.

[0064] In another embodiment of this application, before step S02, the application processor further compresses the aging compensation data. Between steps S03 and S04, the display driver chip further decompresses the aging compensation data. For example, the compression ratio when the application processor compresses the aging compensation data is greater than or equal to 2, so that the preset ratio can be 1:1.

Data encapsulation unit 160 encapsulates the first aging compensation data and the first image data to obtain corresponding serial display data.

[0073] Furthermore, the display driver chip 200 may also include an image processing unit 230 for processing the first image data and providing the processed first image data to the aging compensation unit 250. The image processing unit 230's processing of the first image data includes color enhancement, color calibration, and brightness unevenness calibration.
