Problems solved by technology

Therefore, before the establishment of the new I-V model, if the TFT characteristics change, but the compensation parameters are still generated according to the original I-V model, the brightness compensation of the display panel is prone to large errors.

Abstract

The disclosure relates to the technical field of display and particularly to an OLED pixel compensation method, an OLED pixel compensation device, and a display device. The compensation method comprises steps of: testing driving transistors of the N-th row of sub-pixels to obtain first test information; testing driving transistors of the M-th row of sub-pixels to obtain second test information; calculating a compensation parameter based on the first test information and the second test information; and compensating the N-th row of sub-pixels, the M-th row of sub-pixels and successive a rows of sub-pixels from the N-th row and the M-th row, wherein N = an + b, M = an + c, A >= 2, 0 <= b < a, 0 <= c < a, and a, b, c, n are all integers. The compensation method and device achieve real-time brightness compensation by shortening the update period of the compensation data, thereby improving a compensation effect.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a compensation method for OLED pixels, a compensation device for OLED pixels, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode), as a current-mode light-emitting device, has the advantages of self-luminescence, fast response, wide viewing angle, and can be fabricated on a flexible substrate, and is widely used in the field of high-performance display. According to the driving method, OLED can be divided into PMOLED (Passive Matrix Driving OLED, passive matrix driving organic light emitting diode) and AMOLED (Active Matrix Driving OLED, active matrix driving organic light emitting diode). AMOLED displays have the advantages of low manufacturing cost, high response speed, power saving, DC drive for portable devices, and wide operating temperature range, and are expected to become the next generation o...
