Problems solved by technology
[0004] Although external compensation can perform initial compensation optimization, as the use time increases, the Organic Light-Emitting Diode (OLED) will also begin to age. According to the current compensation method, the OLED cannot be effectively compensated. Therefore, It will cause common image sticking problems, which seriously affect the user experience. At the same time, external compensation usually compensates for each sub-pixel. Therefore, to save all compensation parameters, a large storage space is required. For hardware design and driver implementation It will be more complicated and not conducive to mass production

The invention provides a pixel compensation method, a pixel compensation structure and a display panel, relates to the technical field of display, solves the problem that an external compensation mode in the prior art cannot realize effective OLED compensation, and comprises the following steps: obtaining optical sensing data of a to-be-compensated pixel unit, and determining first compensation data of a first sub-pixel according to the optical sensing data; and determining second compensation data of the second sub-pixel according to the first compensation data, the pixel compensation of all the pixel units is realized by acquiring the optical sensing data of the to-be-compensated pixel unit and determining the first compensation data and the second compensation data of the to-be-compensated pixel unit according to the optical sensing data; only the first sub-pixel is provided with the sensing component, so that the hardware design complexity is reduced, the complexity of a pixel driving program is correspondingly reduced, and the purposes of rapid compensation and storage space saving are achieved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a pixel compensation method, a pixel compensation structure and a display panel. Background technique [0002] As a current-type light-emitting device, electroluminescent components have been increasingly used in display panels. Due to their self-luminous properties, electroluminescent display panels do not require a backlight source, and have high contrast, thin thickness, and wide viewing angle. , fast response, flexible, simple structure and manufacturing process, etc., so the electroluminescent display panel has gradually become the mainstream display panel of the next generation. Generally speaking, a pixel circuit includes a display unit, a thin film transistor (Thin Film Transistor, TFT) and a storage capacitor (Capacitance). Through a fixed scanning wave switching TFT, the voltage corresponding to the display data is charged to the capacitor. The size is contr...
