Title
(EN) Display device and grating control method
(ZH) 一种显示装置及光栅控制方法
Abstract
(EN)
The invention provides a display device and a grating control method, belonging to the technical field of display and solving the problems of high preparation precision and great process difficulty of electrodes of a grating substrate caused by configuration of a pixel array and the problem of high control complexity caused because the electrodes of the grating substrate need to be controlled line by line and one by one in the prior art. The display device has the beneficial effects that as gratings configured corresponding to pixels are adopted, the width of the electrodes of the grating substrate is increased, and then the electrodes are lower in preparation process precision requirements, are convenient to prepare and are lower in costs; switching between 2D display and 3D display of the display device is completed by opening and closing the gratings; meanwhile, the number of electrode control lines is reduced; the structures of the gratings are further simplified.
