A control system for a special-shaped flexible LED display

Abstract

The invention discloses a control system of a special-shaped flexible LED display. The control system is based on a high transparency, highlight, stable performance, ultra-light and ultra-thin special-shaped flexible LED display terminal, under the circumstance of ensuring the universality of a driving bar and avoiding data confusion caused by data address disorder, a main control unit performs "virtual point" insertion operation on a control signal, 0 bit adding setting is conducted to play a position occupation role, thus ensuring the effect of the driving bar. The operation only needs to change the code in the control unit, is simple, and has no need to change the driving bar, the technical cost is low, and waste of resources can be avoided. The LED display adopts a flexible screen, hasthe characteristics of lightness, thinness, transparency, windability, free design and the like, and can meet the needs of more diversified multimedia advertisements.

Description

technical field [0001] The invention relates to the field of control of LED display screens, in particular to a control system for special-shaped flexible LED display screens. Background technique [0002] With the continuous maturity and progress of LED display technology, although the flexible transparent film LED display technology is not mature enough in the development, the flexible transparent film LED display has broken through the traditional method of the previous LED glass display and realized the flexibility of the display. , light and thin, high permeability characteristics. Conventional flexible LED displays are mainly rectangular in shape. Due to their fixed shape, they cannot meet the needs of more diverse multimedia advertisements. Therefore, special-shaped flexible LED displays emerged as the times require. At present, the technology for driving rectangular flexible LED displays is relatively simple. Most of the ways to drive rectangular displays are to use...

AI Technical Summary

Problems solved by technology

Conventional flexible LED display screens use a rectangle as the main display screen shape. Due to its fixed shape, it cannot meet the needs of more diverse multimedia advertisements. Therefore, special-shaped flexible LED display screens emerged as the times require.

At present, the technology for driving rectangular flexible LED displays is relatively simple. Most of the ways to drive rectangular displays are to use row scanning video data to store, each pixel corresponds to an address, and then read the address through column control to compare the data in the address with the The LEDs on the display light up accordingly

At present, the conventional drive bar is to drive 8 rows and 8 columns of LED chips at the same time. The resolution of the special-shaped screen must not be enough to 8×8. If the drive bar is modified according to the resolution of the special-shaped screen, it will inevitably cause problems of high cost and technical complexity. , and the drive bar cannot meet the technical versatility

In the case of cost considerations, if the drive bar is not changed and the current conventional drive bar is used directly, the direct drive of the special-shaped flexible LED display will definitely cause data strings, address data cannot be transmitted accurately, cause garbled characters, and cannot achieve the ideal multimedia.
