Abstract

The invention discloses an aging treatment method and an aging treatment system applied to a display panel. The initial cut-off voltage range of the transistor is determined according to the initial characteristic curve of the transistor that needs aging treatment in the display panel; and the initial cut-off voltage range is determined according to the initial cut-off voltage range. The gate-source voltage and drain-source voltage required by the transistor to increase the cut-off voltage range of the transistor; according to the determined gate-source voltage and drain-source voltage required by each transistor, perform aging treatment on the transistors that need aging treatment in the display panel . In this method, since the aging treatment voltage applied to each display panel is obtained according to the transistors in the display panel, the effect after aging treatment is good, and the process yield and the stability of product TFT characteristics can be effectively guaranteed.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to an aging treatment method and aging treatment system applied to a display panel. Background technique [0002] In the manufacturing process of Organic Light Emitting Diode (OLED) devices, the Thin Film Transistor (TFT) in the OLED device needs to be aged (Aging), referred to as TFT-Aging, to achieve The purpose of eliminating bright spots and ensuring stable TFT characteristics. At present, during the TFT-Aging process, by applying a fixed voltage value to the OLED device, a relatively large stress is formed to act on the TFT, thereby achieving an aging effect. The aging effect is related to Stress, and moderate Stress can increase the yield of OLED devices and increase the stability of TFT characteristics. [0003] At this stage, TFT-Aging is to write a fixed voltage value to the TFT to form a fixed Stress (Vgs and Vds) to act on the TFT, and through multiple debugging, the ideal Ag...
