Embodiment 1

[0053] figure 2 It is a flow chart of an image display method based on pixel compensation provided in Embodiment 1 of the present invention. The method can be executed by an image display device based on pixel compensation, and the device can be implemented by software and / or hardware. Typical It can be integrated in display devices such as televisions. see figure 2 , the method of this embodiment specifically includes:

[0054] S210. Decode the received image signal to obtain the gray scale value of each pixel to be displayed.

[0055] First of all, it needs to be explained that when the display screen is displaying images, it is necessary to control the thin-film transistor (Thin-Film Transistor, TFT) of each pixel unit in the display screen to turn on through the driving voltage, so that the thin-film transistor generates a driving current, so that each pixel unit in the display screen Lights up for image display. Since the number of TFTs corresponds to the number of ...

Abstract

The embodiment of the invention discloses an image display method and device based on pixel compensation, a display device and a medium. The method comprises the steps of decoding received image signals to obtain the gray scale value of each pixel to be displayed; for any pixel to be displayed, determining the gray scale compensation value of the pixel to be displayed according to a preset pixel compensation table corresponding to the gray scale value of the pixel to be displayed, compensating the pixel to be displayed through the gray scale compensation value; and driving the each pixel unitin a display screen to shine by using each target driving voltage so as to display images, by taking the voltage corresponding to each pixel to be displayed after compensation processing as target driving voltage based on the correspondence relation of the pixels to be displayed and the positions of the pixel units in the display screen. By the adoption of the technical scheme, the influence of uneven display brightness of pixels in the display screen on image display is effectively avoided, and the image display quality is greatly improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular to an image display method, device, display device and medium based on pixel compensation. Background technique [0002] Active-matrix organic light-emitting diode panel (active-matrix organic light-emitting diode, AMOLED) referred to as OLED in the present invention has the advantages of low power consumption, self-illumination, good image quality and fast response speed, and is currently developing rapidly and application. Low Temperature Poly-Silicon Thin-Film Transistor (LTPS TFT) and Oxide Thin-Film Transistor (Oxide TFT) have higher mobility and more stable characteristics, and are widely used in display devices with OLED displays. Used to control the driving current of the OLED. [0003] At present, no matter whether LTPS TFT or Oxide TFT is used, the electrical parameters such as the threshold voltage and mobility of the TFT correspon...
