Problems solved by technology

However, limited by the manufacturing process, each driving transistor DT of the OLED pixel often has fluctuations in electrical parameters such as threshold voltage Vth and mobility K, which causes the current flowing through the OLED device to vary with the threshold voltage Vth and migration of the driving transistor DT. The fluctuation of the rate K is different, which will cause uneven brightness and affect the display quality

Abstract

The invention relates to an OLED (organic light emitting diode) pixel compensation method and device as well as a display device and relates to the technical field of display. The OLED pixel compensation method comprises the following steps: acquiring threshold voltage of a drive transistor; acquiring mobility of the drive transistor according to the threshold voltage of the drive transistor; compensating OLED pixels according to the mobility of the drive transistor. The OLED pixel compensation method can compensate pixels and improve definition.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a compensation method and 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 of flat-panel di...
