Abstract

An exemplary operating voltage adjusting method for a flat panel display device including at least a first testing pixel is provided. In the operating voltage adjusting method, a plurality of testing operating voltages are provided. The at least a first testing pixel operative with the testing operating voltages in sequence then is enabled to be charged by a first specific data and a plurality of first data voltages stored in the at least a first testing pixel effected by the testing operating voltages respectively can be obtained. Afterwards, an operating voltage of the flat panel display device is determined according to states of the first data voltages in a testing period. Moreover, an exemplary structure of the flat panel display device also is provided.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular relates to a structure of a flat display device and a method for adjusting its working potential. Background technique [0002] At present, flat panel display devices such as thin film transistor liquid crystal display devices are widely used in consumer products such as mobile phones, notebook computers, desktop display devices, and televisions due to their advantages of high image quality, small size, light weight, and wide application range. Electronic products have gradually replaced traditional cathode ray tube (CRT) display devices and become the mainstream of display devices. [0003] However, because the thin film transistors in the flat panel display device are used in different temperature, humidity, product life, etc., the film quality, defects, carrier mobility and other electrical properties in the thin film transistors will change accordingly, and these ch...
