Embodiment Construction

[0045] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0046] Such as figure 1 As shown, the dual-view display structure in the related art includes a liquid crystal display (LCD, Liquid Crystal Display) and a shield 13 located above the liquid crystal display, and a light-transmitting slit is arranged on the shield 13, and the light-transmitting slit spans adjacent of two pixels. refer to figure 1 The schematic diagram of the implementation principle of dual-view display techn...

Abstract

The invention relates to the field of display technology, and proposes a dual-view display panel and a display device. The dual-view display panel includes a backlight, a liquid crystal grating, a color filter layer, etc.; the backlight is used to provide collimated light; the liquid crystal grating is arranged on the backlight The light output direction of the source; the color filter layer is arranged on the side of the liquid crystal grating away from the backlight source, the color filter layer includes a plurality of first pixel areas and a plurality of second pixel areas, and the adjacent first pixel areas and second pixel areas There is a light-shielding area between them; the liquid crystal grating is used to diffract the collimated light emitted by the backlight to the first pixel area and / or the second pixel area. Since the light passing through the first pixel area and the second pixel area is produced by the diffraction of the liquid crystal grating, the central area cannot see both the first pixel area and the second pixel area, which can avoid the generation of the central crosstalk area .

Description

technical field [0001] The invention relates to the field of display technology, in particular to a dual-view display panel and a display device equipped with the dual-view display panel. Background technique [0002] Dual-view (also called dual-view) display means that the same display displays different images at different angles, that is, users can see different images from different angles of the display. The dual-view display can be applied to a vehicle display. For example, through the dual-view display, passengers in different seats in the car can see different images through the same display, so that there is no need to provide each passenger with their own display. This setting can not only save the cost of display settings, And can reduce the occupancy of the space in the car. [0003] However, the dual-view display panel in the prior art will generate a central crosstalk area, and the existence of the central crosstalk area will greatly reduce the presence exper...
