Problems solved by technology

Furthermore, although the same type of OLED display driver code can be reused, each OLED display still needs to be initialized separately when the driver is executed. If there are 100 OLED displays, the initialization will be repeated 100 times, resulting in relatively low efficiency. It takes a lot of time; and the control is also executed separately, and it is cumbersome
In addition, hardware resources are consumed too much, and I / O ports will not be enough when there are many OLED displays

Abstract

The embodiment of the invention provides a multi-display-screen control system, a display system and a multi-display-screen control method. The multi-display screen control system comprises an embedded processor; a programmable logic device which is electrically connected with the embedded processor and is provided with an enable signal output interface and a display content and configuration information output interface; a display screen enable circuit which is electrically connected with the enable signal output interface of the programmable logic device; and display screen connecting portswhich are electrically connected with the display screen enabling circuit and the display content and configuration information output interface of the programmable logic device. According to the embodiment of the invention, the display control of the plurality of display screens can be realized, the control of the plurality of display screens is simplified, the initialization complexity of the plurality of display screens is reduced, and the control efficiency of the plurality of display screens is greatly improved.

Description

technical field [0001] The invention relates to the technical field of display and control, in particular to a multi-display control system, a display system and a display control method. Background technique [0002] OLED display is a display made of organic light-emitting diodes (Organic Light-Emitting Diode, OLED). Since OLED display has self-luminous organic light-emitting diodes, it does not require a backlight, and has high contrast and wide viewing angle. , fast reaction, wide temperature range and simple structure and process. In practical applications, a large number of OLED displays are sometimes required. The existing technical solution is to configure hardware resources for each OLED display and control each OLED display individually. Furthermore, although the same type of OLED display driver code can be reused, each OLED display still needs to be initialized separately when the driver is executed. If there are 100 OLED displays, the initialization will be repea...
