Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0042] A data transmission method of a series display system of the present invention, such as Figure 4 As shown, the serial display system includes a plurality of driver chips, the number of the plurality of driver chips is n, and n is a positive integer, and the first driver chip is connected to the nth driver chip in a step-by-step series manner;

[0043]The data transmission method of the tandem display system includes:

[0044] Step S101. The first driver chip re...

Abstract

The present invention relates to the technical field of LED lamp control. The present invention provides a serial display system and a data transmission method thereof, comprising: the first drive chip receives a data frame composed of n sets of display data and one set of shared control data; Starting from the first driver chip, the first driver chip extracts its corresponding display data and shared control data from the data frame, and sends the data frame composed of shared control data and other display data to the second driver chip, thus In the process of sequentially executing to the nth driver chip according to the step-by-step series method; in the process of sequentially executing to the n-th driver chip according to the step-by-step series method, each driver chip is controlled according to its corresponding display data and shared control data. The LED lights connected to it are displayed. By using the same control data, it only needs to transmit the control data once. On the basis of not reducing the number of cascaded chips in the series system, the same control function of the series drive chip is realized.

Description

technical field [0001] The invention relates to the technical field of LED lamp control, in particular to a serial display system and a data transmission method thereof. Background technique [0002] At present, the series chips of the series display system in the prior art are connected in series step by step, such as figure 1 and figure 2 As shown, the display data read by the series chip is transmitted step by step from the previous level series chip to the next level series chip, that is, when the Nth level series chip receives the data stream output by the N-1 level series chip, it intercepts the (Nth stage) required display data to control the connected lamps to display corresponding effects, and then output the remaining data to the display device of the N+1th stage series chip. When it is necessary to increase the control function, it is necessary to increase the control data while sending the display data, such as image 3 As shown, a set of control data is adde...
