Embodiment Construction

[0019] Figure 1: Customize the box frame mold first as shown in the figure, splice the mold into a box according to the required size, fix the LED light board and control board on the fixing frame in the box, and inlay the high-contrast screen glass in the box On the frame of the body, seal and fix it with adhesive tape, and finally cover the back cover.

[0020] Figure 2: There is a small platform on the thin side of the box frame, 2 / 3 of the thickness of the screen glass is embedded on the small platform of the thin box frame, and then the screen glass and the box frame are sealed and fixed with high-strength adhesive tape.

[0021] Figure 3: There are positioning pin holes on the upper and lower sides of the cabinet frame, and the upper and lower cabinets are positioned with pins, and then fixed on the back of the cabinet through flanges.

[0022] Figure 4: There are precise positioning screw holes on the 4 corners on the back of each cabinet, and the flange can be accurate...

Abstract

A high-contrast LED display screen is provided, which belongs to the technical field of large-screen display on LED screen and comprises a glare protective screen of high contrast, an LED cell box, a screen and a frame bonding adhesive tape. Each cell box of the LED display requires a screen to increase high-contrast screens. The cell around the box structure is used to support the high-contrast screen whose frame is in the shape of zigzag. The sawtooth is crossed with the LED, and the high-contrast screen is inlaid 0.5 mm to 2.0 mm inside the frame. The width and height of the frame is 0.2mm to 3.0mm larger than that of the high-contrast screen, which has the advantages of waterproof function without the working procedure on glue-pouring in LED screen production, low difficulty and cost for maintenance and improving of the screen contrast.

Description

technical field [0001] The invention belongs to the technical field of large-screen display of a light-emitting diode display (light electronic display, referred to as LED), and in particular provides a high-contrast light-emitting diode display. Background technique [0002] In the LED large screen industry, according to the different packages of LED lights, they are divided into three types: SMD, sub-surface mount, and direct plug-in lights. For full-color LED large screens, each pixel is composed of three-color light-emitting diode lights, which are divided into three colors: red, green, and blue (R, G, and B). All full-color LED large-screen systems, whether they are foreign products or domestic products, are directly exposed by light-emitting diode lights. When it is used outdoors, it is encapsulated with a plastic mask to meet the rainproof requirements. Since the LED large screen is an image display system composed of a large number of red, green, and blue (R, G, B)...
