Abstract

The invention discloses a 3D display device and a control method for the 3D display device, relates to the technical field of 3D display, and aims to solve the problem that the 3D display device with a touch screen function is relatively thick. The 3D display device includes: a liquid crystal grating located on the liquid crystal display module, a detection endpoint for detecting a current value is provided at each of the four corners of the electrodes of the liquid crystal grating; a controller connected to the four detection endpoints for signals, the The controller is used to calculate the contact position according to the current values ​​of the four detection terminals. The 3D display device provided by the present invention is used to realize that the 3D display device has a touch screen function.

Description

technical field [0001] The present invention relates to the field of three-dimensional (Three Dimensional, hereinafter referred to as 3D) display technology, and in particular to a 3D display device and a control method for the 3D display device. Background technique [0002] With the development of display technology, 3D display products and touch screen products are more and more widely used. Therefore, how to combine 3D display substrates and touch screen substrates to obtain 3D display devices with touch screen functions has become an urgent problem to be solved. question. [0003] Currently, see figure 1 , by directly superimposing the touch screen substrate 20 on the 3D display substrate 10 to realize the touch screen function of the 3D display device. Wherein, the 3D display substrate 10 is located on a liquid crystal display module (Liquid Crystal Display Module, LCM) 31, and the 3D display substrate 10 includes: a lower substrate 11, an upper substrate 12, electro...
