Problems solved by technology

When displaying, the circular screen rotates around the central axis. By controlling the display and refresh of the image on each light pole, the circular screen display effect is realized. The displayed image has no stitching gap, but the stability of the dynamic image is poor, which affects the viewing effect

Embodiment Construction

[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0047] Such as figure 1 As shown, this embodiment provides a ring-shaped transparent screen, which includes a ring-shaped screen 1 and a driving mechanism 2, and the driving mechanism 2 is connected to the ring-shaped screen 1 for driving the ring-shaped screen 1 to rotate around its own axis. The driving structure includes a power source and a central shaft 21 , and the central shaft 21 is arranged inside the annular screen 1 and coincides with the axis of the annular screen 1 . The power source is connected in transmission with the central shaft 21, and the central shaft 21 is connected with the ring screen 1, so that the ring screen 1 is driven to ro...

Abstract

The invention discloses a control method of a circular screen, which relates to the technical field of display. The ring screen includes a plurality of light poles arranged in a ring. The control method of the ring screen includes real-time detection of the position information of each light pole in the ring screen, and controlling the display content and display position of the light poles according to the position information. And judging whether the ring screen needs to be stopped for adjustment. In this control method, the position information of each light pole is detected in real time, and the display content of each light pole and the position displayed on the light pole are corrected according to the position information, so as to improve the stability of the dynamic display of the ring screen and facilitate the installation of light poles. When there is a large deviation in the position, stop the machine for inspection and adjustment in time.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for controlling a circular screen. Background technique [0002] There are many ways to realize the ring screen display, mainly including multi-screen splicing, ring screen projection and static LED screen. Among them, there is at least a 1mm gap between the screens in the multi-screen splicing structure, and the overall picture display effect is poor; the contrast of the ring screen projection is poor, and there are problems such as defocusing and low brightness; the resolution of the static LED screen is poor. High cost, not suitable for close viewing. [0003] A ring screen display structure is proposed in the prior art, wherein the ring screen includes a plurality of light poles arranged in a ring. When displaying, the circular screen rotates around the central axis. By controlling the display and refresh of the image on each light pole, the circular screen displa...
