Description

Technical Field

[0001] The utility model relates to the display field, in particular to a display screen. Background Art

[0002] Large LED display screens are generally used for multimedia display, and are usually composed of multiple LED display boxes. Existing LED display boxes are generally rigid structures that cannot be bent and cannot adapt to changing display environments or requirements. The curved display of existing LED display screens is to use many rigid boxes to connect, and then connect them with arc locks, and then connect these LED boxes with wires, connect the power supply and control system to form a curved LED display screen.

[0003] This structure has the following disadvantages: 1. The connection between the two boxes will have edges and corners, which are not arcs, causing sudden changes in the display direction and seriously affecting the display effect; 2. Due to the error in processing accuracy, the size of the box will have errors, which will cause a certain gap between the boxes, and these gaps are different from the LED pixel spacing; 3. The arc lock connection requires manual operation, so it is difficult to align the curved scale and maintain accuracy, that is, it is difficult to splice the arc of multiple boxes, which consumes a lot of manpower, material resources and time. 4. Independent LED display unit boards are respectively provided on the two adjacent boxes. Therefore, there will be a gap between the two adjacent LED display unit boards, and the gap is easily uneven due to the connection of the boxes, which visually presents "dark lines" or "bright lines".

[0004] In addition, the existing flexible display screen uses a motor to change the angle between the boxes. The adjacent boxes are connected by a motor. A motor is set on one box and then connected to another box. The angle between the two boxes is changed by driving the other box to move. This structure requires a motor to be set for every two boxes, which results in a large number of motors, high installation cost and high manufacturing cost. Utility Model Content
