Abstract

An image display driving device, a display device and an electrical compensation method. The image display driving device includes a detection circuit and a data superposition circuit. The detection circuit is configured to obtain the electrical compensation data signal of the display panel; the data superposition circuit is configured to superimpose the electrical compensation data signal and the initial driving data signal to obtain a compensated driving data signal. The image display driving device, the display device and the electrical compensation method realize the improvement of system integration and response speed.

Description

technical field [0001] Embodiments of the present disclosure relate to an image display driving device, a display device and an electrical compensation method. Background technique [0002] Organic Light Emitting Diode (OLED) display panels are gradually gaining popularity due to their advantages such as wide viewing angle, high contrast ratio, fast response speed, higher luminance and lower driving voltage compared to inorganic light emitting display devices. widespread attention. Due to the above characteristics, the organic light emitting diode (OLED) display panel can be applied to devices with display functions such as mobile phones, monitors, notebook computers, digital cameras, and instruments. However, the organic light emitting diode display panel has the problem of non-uniform display brightness. Generally, the method of optical compensation or electrical compensation can be used to improve the uniformity of the display brightness of the organic light emitting di...
