Abstract

The invention relates to a display control circuit, a display control method, a display module and a display device. The circuit comprises a receiving unit used for receiving to-be-displayed data sent by a host, converting the to-be-displayed data into first transmission data and outputting the first transmission data to a data management unit when the display control circuit is connected with the host; the data management unit is used for receiving first transmission data or data from the cascade input port; if the received data is the data of the scanning block, storing the data; otherwise, transmitting the data to a cascade output port; the scanning control unit is used for generating a scanning signal according to the data stored in the data management unit; and the display driving unit is used for driving the LED dot matrix corresponding to the scanning block to display according to the scanning signal. Therefore, the display control circuit can provide integrated control functions of network communication, scanning control, display driving and the like, and has the characteristics of multiple functions, integration, high refresh frequency and the like, so that the display device is stable in picture, optimized in process, simple in structure and relatively low in cost.

Description

technical field [0001] The present disclosure relates to the field of LED display, in particular, to a display control circuit, a display control method, a display module and a display device. Background technique [0002] Display devices (for example, LED display screens) have been quite mature after several decades of development, and these years are more technologically oriented to improve technology and increase pixel density to improve display effects. However, as far as its system structure is concerned, the display device has not changed substantially. For example, the synchronous LED display body has always maintained a ternary structure of display module, receiving card and switching power supply. This structure makes the manufacture and installation of the synchronous LED display body more complicated, professional and engineering, and easy Failures occur frequently. In addition, as the spacing between LED dot matrixes continues to decrease, the microelectronic c...
