Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] refer to figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the integrated imaging display device of the present invention. The display device 100 includes: a switchable backlight module 101 and a liquid crystal display panel 102 .

[0024] Among them, the liquid crystal display panel 102 is a device that uses the electro-optic properties of liquid crystal molecules to display images, and is widely used in mobile phones, computers, LCD TVs and other equipment. The element image array is displayed on the liquid crystal display panel 102, which contains the information of the three-dimensional scene. The switchable backlight module 101 includes a point light source array 1011 and a surface light source 1012 . The point light source array 1011 and the surface light source 1012 are stacked sequentially, and the ...

Abstract

The invention discloses an integrated imaging display device and its backlight module. The display device comprises: a switchable backlight module and a liquid crystal display panel, wherein the switchable backlight module is switched between at least a first working mode and a second working mode, and the second The first working mode is the dot matrix backlight formed by the point light source array, enabling the display device to realize 3D display, and the second working mode is the surface light source backlight, enabling the display device to realize 2D display. Through the above method, the present invention can realize switching of 2D / 3D display mode by switching the working mode of the backlight module.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to an integrated imaging display device and a backlight module thereof. Background technique [0002] With the improvement of stereoscopic display technology, many brands of 3D displays have realized the naked-eye stereoscopic display function, that is, it is no longer necessary to wear accessories such as 3D glasses, and the 3D effect can be seen directly with human eyes. But at the current stage, stereoscopic display technology has yet to be perfected. When the frequency of image changes is high, the current 3D display screen switching is not very smooth when the 3D image is changed, which is easy to bring dizziness to the viewer, and the viewer will very much hope to see the 2D image. Therefore, it is necessary to design a 2D / 3D switchable display. [0003] In the field of stereoscopic display, 2D / 3D switchable displays have been invented. The invention realizes 2...
