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 technical field of display and provides a double-vision display panel and a display device. The double-vision display panel comprises a backlight source, a liquid crystal grating, a color film layer and the like; the backlight source is used for providing collimating light; the liquid crystal grating is arranged in the light emitting direction of the backlight source; the color film layer is arranged on the side, away from the backlight source, of the liquid crystal grating, the color film layer comprises a plurality of first pixel areas and a plurality of second pixel areas, and shading areas are arranged between the first pixel areas and the second pixel areas which are adjacent to each other; the liquid crystal grating is used for diffracting the collimating light given out by the backlight source to the first pixel areas and / or the second pixel areas. Light rays which penetrate through the first pixel areas and the second pixel areas are generated through diffraction of the liquid crystal grating, therefore, the first pixel areas and the second pixel areas cannot be observed on a central area at the same time, and the generation of a central crosstalk area can be avoided.

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...
