Rotary display screen

Abstract

The invention relates to the technical field of display devices and discloses a rotary display screen. The rotary display screen comprises a motor, a fixing body and a rotary frame installed on the fixing body. The rotary frame comprises a plurality of LED modules. Each LED module comprises a plurality of LED elements. The arrangement height of the LED elements of at least one first LED module is different from that of the LED elements of at least one second LED module. According to the rotary display screen, the arrangement modes of the LED elements in the LED modules are changed so that combinations of different residual images formed by height differences of the elements can be fully used to fill gaps between the elements, the pixel pitch of a displayed image can be effectively reduced, soft images with the high resolution ratio can be displayed under the condition that the number of the LED elements is not increased, and therefore the problem that the resolution ratio of the rotary display screen is limited to the installation gaps of the elements is solved.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a rotating display screen. Background technique [0002] Due to LED (Light-Emitting Diode, light-emitting diode) low operating voltage, low energy consumption, long life, can actively emit light and high brightness, the brightness can also be adjusted by voltage (or current), plus its own impact resistance, anti- Advantages such as vibration, the current large-scale indoor and outdoor display boards basically use LED displays as display devices. However, limited by the way of thinking of traditional display technology, most of the existing large-scale electronic display boards are flat display boards, which only use a large number of LED lights to form a flat dot matrix for display, and do not make full use of the advantages of relatively independent LED lights and flexible display methods. The existing planar display method uses a large number of LED lamps, generates a ...

Problems solved by technology

[0005] However, the rotating display screen in the prior art has a biggest problem: the resolution of the display screen is determined by the gap P of the LED lights. Theoretically, the smaller the gap P, the better the display effect; Due to limitations, the gap between LED components cannot be reduced infinitely, and a certain space must be reserved for circuit wiring and device layout. Therefore, the resolution of traditional rotating display screens is limited, and true high-definition display cannot be realized.
