Problems solved by technology

[0004] In addition, in the prior art, there is also a device for dual-view display using a lenticular grating, which is affected by factors such as the distance between the lenticular grating and the pixel plane of the display panel, the thickness of the glass substrate on the display surface, and the refractive index of the lenticular grating. Influence, causing the deflection angles of the light beams to the two viewers respectively to be small, so crosstalk between the two images displayed to the two viewers is prone to occur

Embodiment Construction

[0034] image 3 Shown is a schematic structural diagram of a time-division multi-view display device provided by an embodiment of the present invention, and the device includes: a display panel 31 , a liquid crystal shutter array 32 and a control module 33 .

[0035] Wherein, the display panel 31 includes N pixel unit columns along the horizontal direction, N is a positive integer greater than or equal to 2, each pixel unit column includes at least one sub-pixel column, and the width of each pixel unit column is equal. The images to be provided to each viewer are divided in advance into several sub-images for viewers in units of pixel unit columns of the display panel 31 . The image resolution to be provided to each viewer is equal to the resolution of the display panel.

[0036] when image 3 When the shown device is working, the control module 33 controls the display panel 31 to display several sub-images for viewers corresponding to at least two viewers in at least two co...

Abstract

The invention discloses a time division multiple visual display device, including a display panel, a liquid crystal shutter array and a control module, wherein, the control module is used to control the display panel so that it displays several looker sub-images corresponding to at least two lookers in at least two permanent display time; all sub-images for the looker corresponding to each looker constitute an integral image to be provided to the looker, the control module is also used for synchronized control of liquid crystal shutter array to form a narrow slit raster corresponding to the current display panel at each display time of the display panel; and the narrow slit respectively guides the sub-images for each looker displayed by the display panel to the corresponding looker. The time division multiple visual display device provided by the present invention has large observation angle, small crosstalk, high resolution and strong practicability.

Description

technical field [0001] The invention relates to the display field, in particular to a time-division multi-view display device and a time-division multi-view display method for the device. Background technique [0002] Dual-view display technology is a technology that enables the display to display different images to viewers in different directions at the same time. This technology has many application fields, the most typical application is on the car TV, the driver sitting on the side of the screen sees the GPS navigation map on the screen, while the passenger sitting in the co-pilot seat sees it on the same screen. to other pictures or programs. [0003] figure 1 Shown is a schematic structural diagram of an existing dual-view display device. Wherein, a slit grating 12 is arranged in front of the display panel 11, two adjacent pixel columns of the display panel 11 correspond to one slit of the slit grating 12, and the even pixel columns of the display panel 11 are used...
