Problems solved by technology

[0004] However, based on the 3D image presented by the lenticular lens, the position of each pixel point and the lens is relatively fixed, and mutual interference cannot occur. The requirements for setting the position of the pixel point are relatively high, and the viewer needs to be in a specific position when watching it. Experience the naked-eye 3D display effect, which brings a lot of inconvenience to the viewers and affects the naked-eye 3D experience
In addition, the spacing between left-eye pixels and right-eye pixels can only occupy half of the screen area, which obviously reduces the resolution of the screen display

Embodiment 1

[0025] Figure 2a A structural top view of a display screen provided in Embodiment 1 of the present invention, Figure 2b A structural top view of a display screen provided in Embodiment 1 of the present invention, Figure 2c It is a front view of the structure of a display screen provided by Embodiment 1 of the present invention, Figure 2d A structural front view of a display screen provided in Embodiment 1 of the present invention, wherein the display screen 210 includes a plurality of pixels 220 arranged in an array.

[0026] Each pixel is provided with at least two luminous sources, the luminous sources are fixed on the fixed plate, and are separated by a set distance in the direction perpendicular to the plane of the display screen, and each luminous source is used for the light emitted by the luminous source Image data representing pixels.

[0027] The rotation driving device is used to drive the rotation angle of the light emitting source to adjust the direction of ...

Embodiment 2

[0051] Figure 3a It is a schematic diagram of the positional relationship between two types of light sources and eyes in a display screen provided by Embodiment 2 of the present invention. This embodiment optimizes Embodiment 1. Specifically, this embodiment further describes the pixel points corresponding to The classification and position orientation of light sources, etc.

[0052] Each of the light-emitting sources is divided into a left-eye light-emitting source and a right-eye light-emitting source;

[0053] The light source for the left eye is set to emit light toward the left eye outside the display screen;

[0054] The light source for the right eye is arranged to emit light toward the position of the right eye outside the display screen.

[0055] In this embodiment, each of the light sources can be divided into at least a left-eye light source 310 and a right-eye light source 320; the left-eye light source 310 is set to emit light toward the left eye position 340 o...

Embodiment 3

[0073] On the basis of the above embodiments, the display screen may further include: a human eye position identification module, located in the display screen, used to identify the human eye position of the viewer in front of the display screen and the distance between the display screen and the human eye position. distance. In this embodiment, the human eye recognition module can be obtained through image recognition by a camera in front of the screen. The camera captures the image of the face in front of the screen through a lens and projects it onto the surface of the image sensor, and judges the position of the human eye in the image through image recognition technology. The specific position, and then determine the position of the human eyes of the viewer in front of the display screen and the distance from the display screen according to various parameters such as the size and shape of the image, and send the image of the eyes and related data to the eye distance recogni...

Abstract

The invention discloses a display screen and a display device. The display screen comprises a plurality of pixel points arranged in an array, each pixel point is provided with at least two light emitting sources, the light emitting sources are fixed on a fixed plate and are arranged on a direction vertical to the plane of the display screen at a set distance interval, and each light emitting source is sued for presenting image data of the pixel points through the light emitted by the light emitting source. A rotation driving device is used for driving the light emitting source to rotate for anangle to adjust the direction of the emergent light. According to the display screen and the display device provided by the embodiment of the invention, the light emitting sources of the pixel pointsare driven by the rotation driving device to rotate, so that a viewer can obtain the viewing experience at any location in front of the screen.

Description

technical field [0001] Embodiments of the present invention relate to image display technologies, and in particular, to a display screen and a display device. Background technique [0002] Glasses-free 3D is currently a popular development direction of display technology. It displays pictures through a display screen, allowing viewers to watch pictures with 3D effects without wearing special 3D glasses. [0003] The current naked-eye 3D display technology solutions, such as figure 1 As shown, it is realized by setting a special lens on the viewing side of the conventional display screen. The display screen includes a plurality of pixel points 110 arranged in an array, and each pixel point 110 is an independent display unit in the display screen. In each frame of the naked-eye 3D video frame, left-eye pixel points 111 and right-eye pixel points 112 have been preset, and are usually evenly spaced. When the naked-eye 3D video image is input to the display screen, the frame o...
