Problems solved by technology

[0005] Yet, because this method utilizes the structure of grating to realize, so current dual-view display, the viewing angle of its left and right sides (such as figure 1 α and β) are fixed and cannot be flexibly adjusted as needed
And the viewing angle of the dual-view display (such as figure 1 α+β) is also very limited, which is not conducive to users' viewing

Embodiment Construction

[0030] The dual-view display of the present invention will be described below in conjunction with the accompanying drawings.

[0031] see figure 2 , is a schematic structural diagram of an embodiment of a dual-view display in the present invention.

[0032] The dual-view display includes a backlight module 10 , a display panel 20 and an optical deflection module 30 arranged adjacently. Wherein, the optical deflection module 30 is disposed between the backlight module 10 and the display panel 20 .

[0033] The backlight module 10 is used to emit collimated backlight. The collimated backlight can be realized by using a laser light source as the backlight source, or by designing a common backlight source plus an optical module with a collimating effect, such as using conventional fluorescent tubes (Cold Cathode Fluorescent Lamps, CCFL) plus Install a suitable light guide plate.

[0034] The optical deflection module 30 is used to divide the collimated backlight emitted by th...

Abstract

The invention relates to a dual-vision display, which comprises a backlight module (10), an optical deflection module (30) and a display panel (20), wherein the backlight module (10) is used for emitting collimated backlight; the optical deflection module (30) is used for dividing the collimated backlight into first-part light with a first deflection angle and second-part light with a second deflection angle; and odd pixel rows and even pixel rows of the display panel (20) are respectively illuminated by the first-part light and the second-part light. The dual-vision display can adjust a display visual angle and can obtain a large visual angle.

Description

technical field [0001] The present invention relates to a display, and more specifically, to a dual-view display. Background technique [0002] With the development of display technology, a dual view display (Dual View Display) appears. This kind of display can display different images on the same display screen, and show them to the viewers on the left and right of the display respectively. [0003] For example, in a car, the driver needs to view the Global Positioning systems (Global Positioning systems, GPS) through the monitor, and the passenger needs to watch the entertainment program through the monitor. At this time, if there is only one monitor, conflicts may arise. The new technology of dual-view display can solve this problem well, which allows the driver to check the GPS while the passenger next to the driver can watch a movie. [0004] The existing dual-view display utilizes a grating to divide adjacent pixels into two pixel areas belonging to the left-side vie...
