Problems solved by technology

[0003] In the prior art, the 3D touch screen using visually impaired technology is more common to use a liquid crystal panel for display, a polarizing film and a switchable liquid crystal surface. The switching liquid crystal panel and the polarizing film form a parallax barrier unit. This structure can realize 3D and 2D display conversion, but the 3D touch screen in the prior art has high cost and large thickness
In the prior art, there is also a method of directly bonding a layer of film with a parallax barrier on the surface of the liquid crystal panel / display module, but there is a problem of bonding accuracy, and there is a deviation in the correspondence between the light and dark stripes of the parallax barrier and the positions of the pixels. , the 3D observation effect obtained by the audience at different viewing angles will be significantly different. When there is a serious deviation in the fit, it is difficult to obtain the ideal effect directly in front of the screen

Abstract

The invention discloses a light barrier-type 3D liquid crystal display screen and a production method thereof. The light barrier-type 3D liquid crystal display screen production method comprises the following steps: (1) an optical lens is provided; and (2) light and shade stripes for forming parallax barrier effects are made on the optical lens. According to the light barrier-type 3D liquid crystal display screen and the production method thereof, through directly making the light and shade stripes for forming parallax barrier effects on the optical lens, the high corresponding precision exists between the light and shade stripes for forming parallax barrier effects and pixel points, and thus, the display screen has excellent 3D display effects.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to a light barrier type 3D liquid crystal display screen and a production method thereof. Background technique [0002] In the existing 3D display liquid crystal display devices, there are mainly the following methods: Visual barrier technology, also known as light barrier type, adds a combined light projection between the backlight module and the LCD panel or between the LCD panel and the human eye The striped parallax barrier is formed by the parallax barrier and the blocking area, which can separate the visual images of the left and right eyes, so as to realize the 3D observation effect; lenticular lens technology, the focus of a layer of lenticular lens added on the LCD panel corresponds to the liquid crystal The pixel points of the panel are projected through the lenticular lens and projected repeatedly at a certain angle after reflection, so that the eye...
