Amoled image processing method, driver chip and wearable device

Abstract

The invention discloses an AMOLED image processing method, a driver chip and a wearable device. Since the boundary between the display image area and the background image area that does not coincide with the pixel row direction and the column direction can be determined in advance, therefore, The positions of the gray-scale transition regions adjacent to the edge can be pre-stored in the AMOLED driver chip. In this way, after receiving the image data sent by the main board, the stored position of each gray-scale transition area, as well as the gray scale of the first pixel in the display image area adjacent to each gray-scale transition area and the gray scale of the first pixel in the background image area can be directly stored. Two-pixel grayscale, adjust the grayscale of the third pixel contained in each grayscale transition area, so that the grayscale of the third pixel is between the grayscale of the first pixel and the grayscale of the second pixel, so as to reduce the difference between the displayed image area and the grayscale of the second pixel. The brightness and contrast of edges between background image areas can effectively reduce edge aliasing and enhance customer experience.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an AMOLED image processing method, driving chip and wearable equipment. Background technique [0002] The current mainstream display devices are generally liquid crystal display panels (LCD, Liquid Crystal Display) or active organic electroluminescence display panels (AMOLED, Active-Matrix Organic Light Emitting Diode). Compared with liquid crystal display panels, active organic electroluminescent display panels have the advantages of faster response speed, higher contrast, wider viewing angle, lower power consumption, and smaller module thickness. [0003] Moreover, the use of AMOLED in wearable products can be thinner and lighter in terms of shape specifications. Therefore, more and more wearable products currently use AMOLED as displays. However, wearable products, especially SmartWatch, most of the products have a circular display. When an array of pixels is used to displa...
