Description

Multi-angle light-emitting display unit with 2D or 3D simultaneous sub-area display or full screen Function switching display device

The present invention relates to a display unit and a display device thereof, and more particularly to a multi-angle light-emitting display unit and a display device thereof having 2D/3D simultaneous sub-area display or full-screen function switching.

Since the distance between the left eye and the right eye pupil is about 6.0cm~7.0cm, the image information received by the two eyes is slightly different because of the difference in viewing angle, and the human brain has two different perspective images to generate depth perception. Function, so the human eye will form a stereoscopic effect when viewing the object.

In the field of stereoscopic display technology, the prior art is mainly divided into: glasses type and naked eye type 3D display technology. The naked-eye 3D display technology is also used in most display products with a lenticular lens and a parallax barrier.

In general, the naked-eye 3D display technology needs to be presented with a liquid crystal display panel to present a stereoscopic image, which is not only complicated in process, high in cost, but also requires high precision in pixel alignment and assembly precision of the grating and the liquid crystal panel. Especially for large-size display screens, the naked-eye 3D display products with gratings are relatively high in defect rate and manufacturing assembly cost, and because the process of liquid crystal panel and grating lens has limitations in area size, it is not suitable for large areas. Display the application of the product.

Since the grating lens in front of the liquid crystal panel is for the naked eye 3D, the 2D image or text presentation is affected. Existing conventional techniques for switching 2D or 3D display modes are mostly implemented using optoelectronic components or moving optics, but are not commonly used in today's products. Similarly, if the LED display screen is similar to the front of the liquid crystal panel by adding a grating lens such as a lenticular grating and a slit grating to achieve 3D display or 2D display mode switching, similar disadvantages as described above may occur, especially for large LED display screens. If the 2D content display is played after the lens is added, it will be affected by the lens, and it will be impossible to display 2D or 3D content in different areas of the screen at the same time, and the screen area for displaying 2D or 3D content cannot be dynamically changed.

In CN203930226U, a naked-eye 3D display pixel unit is used to form a multi-view naked-eye 3D display device. The optical package includes an optical guiding region and a light mixing region, wherein the light mixing region can transmit light emitted by the sub-pixel unit to the optical package through reflection, refraction or total reflection, and guide to the optical guide. a region, the optical guiding region corresponding to the sub-pixel unit, the optical guiding region guiding the light emitted by the sub-pixel unit to deflect the beam to different directions, or guiding the optical package through the baffle blocking function In vitro, the pixel unit is effectively caused to emit left and right eye parallax images, and then to the two eyes of the viewer, the brain perceives the parallax image and merges to form a volume image.

Because the naked-eye 3D display unit is minimized to the part level, the naked-eye 3D display pixel unit can be vertically and horizontally arranged to form a display unit module or a box according to the purpose and the indoor/outdoor installation site requirement, and the plurality of display unit modules can be spliced. Large-area display screens with different area sizes, convex curved shapes, concave curved shapes or free-form surface shapes, without the need to install optical lenses in parallel in front of the display screen, completely independent of the lens area size, freely expand seamlessly into a matching Display screens that are required for different shapes and sizes.

In addition, the naked-eye 3D display unit is matched with the full-color LED, and the rows and columns are alternately arranged adjacent to each other on the circuit substrate to form a display unit module, and assembled into a large-area screen. The system can alternately turn on or off the light through the multi-angle light-emitting display unit and the full-color LED to switch the 2D and 3D image display modes. When the full-color LED is lit, the multi-angle light-emitting display unit is turned off, and the screen displays a 2D image. On the contrary, when the multi-angle light-emitting display unit is lit, the screen displays a 3D image at this time.

Therefore, the 2D content can be played in the full-color LED area of the display screen at the same time, and the naked-eye 3D content can be played in the naked-eye 3D display unit area. Or switch the 2D or 3D display mode in real time according to the content of the program. This device requires the naked eye 3D display unit and the LED display device to be adjacent to each other, but controls the brightness, color and gray level consistency of two adjacent components. There are difficulties, and because the naked-eye 3D display unit and the LED are arranged adjacent to each other to display 3D and 2D messages, respectively, the result will be a reduction in the resolution of the 2D and 3D images.

In view of this, how to completely get rid of the conventional 3D display method such as the lenticular lens and the slit grating, so that a light-emitting display unit can timely emit light or change its light-emitting angle according to 2D or 3D content playback. When it receives the 2D image message, the display screen displays the 2D content, and when the 3D image message is received, the oblique light is emitted and the 3D parallax image is formed with the adjacent light-emitting display unit, so that the viewer can view the 3D content. The light-emitting display unit can evenly arrange a high-resolution large-area display device with a small pitch, so that the 2D or 3D image can be switched with the play, the content display dynamic mutual function, and the 2D and 3D content are displayed at the same time. The function displayed in different areas of the screen. This kind of function has the necessity to mix and play various 2D or 3D video/picture or text content on the large display screen, and can make the program content playback arrangement diversified, and increase the display screen design flexibility. It is today's glasses type 3D and others. The conventional naked eye stereo display technology is insufficiency.
