Abstract

The invention discloses a developing analysis algorithm of an OLED display driving circuit. The developing analysis algorithm of the OLED display driving circuit comprises the following steps: a, image partition; b, voltage selection; c, image quality estimation; and d, color replacement. The image obtained after replacement of the control current is statistically estimated in the pixel luminance again. If the estimation is passed, the final image is formed. If the image in partial area is still in distortion, then power supply voltage is increased. And the step b is repeated. The invention also discloses a network application method of the developing analysis algorithm, comprising the following steps: performing development analysis to a video stream in advance by a developer of a picture or a video, and producing a voltage adjustment file relative to the video for download by users; and automatically downloading and uploading the voltage adjustment file relative to the watched video when the users watch the video in network media terminal software.

Description

technical field [0001] The invention relates to an imaging analysis algorithm of an OLED display driving circuit and a network application method thereof. Background technique [0002] With the development of the information age, the development of various mobile multimedia devices based on mobile phones and tablet computers has made great progress. At the same time, people's demand for display devices is increasing day by day, and their requirements on energy consumption and image quality are also becoming stricter. In recent years, the design and manufacture of traditional displays are mainly based on LCD (Liquid Crystal Display) technology. The display uses the bottom backlight as the light source, and the light of each pixel changes direction through the upper LCD rod-shaped crystal molecules, and separates different colors in the filter layer to produce a picture. However, the light emitted by the backlight panel of LCD technology cannot be effectively utilized in the...
