Abstract

The invention provides a testing system used for a display device, wherein, the display device is provided with at least a display panel; the testing system comprises a control unit and a vibration unit; the control unit controls the display panel so as to display the picture plane; the vibration unit vibrates the display panel by at least a vibration frequency; furthermore, the vibration frequency practically trends to one of a plurality of natural frequencies of the display panel. Furthermore, the invention also provides a test method used for the display device.

Description

technical field [0001] The invention relates to a testing system and testing method of a display device. Background technique [0002] With the development of display technology, the industry has developed a variety of display devices for consumers to choose from, for example, cathode ray tube display devices, plasma display devices, field emission display devices or liquid crystal display devices and so on. [0003] Generally, a known liquid crystal display device includes a display panel and a driving circuit. The display panel has a thin film transistor substrate, a color filter substrate and a liquid crystal layer. The liquid crystal layer is arranged between the electrode array of the thin film transistor substrate and the common electrode of the color filter substrate. The driving circuit can control the voltage difference between the electrode array and the common electrode to make the display panel display images. [0004] Generally speaking, the industry will con...
