Title
(EN) Overhauling method and driving method of display device, and display device
(ZH) 一种显示装置的检修方法、驱动方法及显示装置
Abstract
(EN)
The invention discloses an overhauling method and driving method of a display device, and the display device. The display device comprises a display panel, a driving module, and a power module for providing voltage required by the display panel and the driving module; screen grid driving circuits are arranged on the display panel, a grid line in the display panel is opened by receiving the screengrid driving signal output by the driving module; the screen grid driving circuits comprise a first screen grid driving circuit and a second screen grid driving circuit; the first screen gird drivingcircuit and the second screen grid driving circuit are located at two sides of the display panel; the screen grid driving signal comprises a first frame starting signal and second frame starting signal independent from each other; the first frame starting signal controls the first screen grid driving circuit, and the second frame starting signal controls the second screen grid driving circuit. Theinvention provides an overhauling method and driving method of the display device capable of being realized through unilateral driving and bilateral driving, and the display device.
