Abstract

The invention discloses an organic light emitting display system and a brightness nonuniformity eliminating method of the organic light emitting display system. The conduction voltage Vth value of each OLED (organic light emitting diode) device is calculated, then, the amplitude value of the display data voltage is changed through the conduction voltage Vth value for compensating the Vth difference, so the problem of brightness nonuniformity of an organic light emitting display is eliminated, the display quality of the organic light emitting display is improved, and the user experience is enhanced. The organic light emitting display system disclosed by the invention can be integrated in a display panel (such as an OLED panel), and the display panel can be installed in various electronic devices such as mobile telephones, digital cameras, mobile phones, notebook computers and the like.

Description

technical field [0001] The invention relates to an organic light-emitting display technology, in particular to an organic light-emitting display system capable of eliminating uneven brightness, and a method for eliminating uneven brightness of the organic light-emitting display. Background technique [0002] With the progress of science and technology, liquid crystal display (Liquid Crystal Display, LCD) has gradually replaced the traditional bulky cathode ray display (Cathode Ray Tube, CRT) because of its advantages of small size and light weight, and has been widely used Used in monitors, notebook computers, flat-panel TVs, digital cameras and other electronic products. [0003] The LCD requires a light emitting diode (Light Emitting Diode, LED) as a backlight source. Organic Light Emitting Diode (OLED) displays do not require a backlight module, are more suitable for thin displays, and have the advantage of no viewing angle restrictions, so they tend to replace tradition...
