Method for accomplishing negative impulse annealing by data writing, its device and driver circuit

Abstract

The present invention discloses a method and a device for realizing negative impulse anneal by data writing, and a driving circuit thereof. The characteristic of a TFT in an active matrix driving OLED display device for driving OLED device is prevented from drifting, the service life of the device is prolonged. The technical proposal is that: within each frame display period, the method of the present invention comprises writing display data line by line for all pixels in a first scan period; writing anneal data line by line for all pixels in a second scan period. Or the method, in each frame display period, comprises writing the first part of the display data or the first part of the anneal data line by line for all pixels in the first scan period; writing the second part of the display data or the second part of the anneal data line by line for all pixels in the second scan period; wherein the display data is written into each pixel in one of the two scan periods of one frame display period, and the anneal data is written in the other scan period. The invention is applied in the liquid crystal display device field.

Description

technical field [0001] The present invention relates to a negative pulse annealing method, device and driving circuit for realizing black picture insertion, and in particular to a method, device and a negative pulse annealing method for implementing negative pulse annealing in a data writing mode applied in an active matrix organic light-emitting display. Drive circuit. Background technique [0002] An organic light emitting display device (OLED) is an active light emitting device. Compared with the current mainstream flat-panel display technology Thin Film Transistor Liquid Crystal Display (TFT-LCD), OLED has the advantages of high contrast, wide viewing angle, low power consumption, and thinner volume. It is one of the most concerned technologies in flat-panel display technology. [0003] OLEDs can be driven with either a passive matrix (PM) or an active matrix (AM). Compared with the PM driver, the AM driver has the advantages of larger displayed information capacity, l...

Problems solved by technology

This display technology has the disadvantage of a long Motion Picture Response Time (MPRT for short). As a result, when displaying a high-speed motion picture, the user will observe that the image boundary will appear blurred.

When the existing technology improves the life and uniformity of AMOLED devices, it cannot shorten the MPRT value of the display device, that is, it cannot solve the problem of blurred dynamic images.
