Abstract

A frameless display device is formed by jointing a plurality of display units; each display unit includes a display panel, a frame, a backlight module, and an image lengthening element; the display panel includes a display surface and a non-display surface opposite to the display surface; the frame forms on edges of the display panel and surrounds the display panel; the backlight module is opposite to the non-display surface; the backlight module includes backlight light sources; the image lengthening element faces the display surface; each display unit also includes a light compensation module; the light compensation module is near the frame and includes a light guide plate and compensation light sources; and a gap is formed in a part corresponding to the backlight light sources, of the light guide plate; light of the backlight light sources passes through the gap to the display panel. The frameless display device can avoid dark display frames with uneven light.

Description

technical field [0001] The present invention relates to a display device, in particular to a frameless display device composed of several display units. Background technique [0002] Large-sized display devices, such as outdoor display screens, have been widely used in various video control centers, outdoor advertising and other fields. Since the maximum size of a single display can only be 100 inches, the outdoor display screen is generally composed of a plurality of relatively small-sized display units, and the plurality of display units cooperate to display an overall picture. However, each display unit includes a frame, which causes the picture displayed on the entire outdoor display screen to be divided by the frame, resulting in discontinuous picture display, thereby affecting the display effect. [0003] In the prior art, an optical structure is often used to elongate the picture near the frame to solve the above problems. In this way, the light emitted by the same ...
