Embodiment Construction

[0015] like image 3 The type of color LED light beam string shown with embedded serial transmission drive control chip is composed of several light beams with RGB combination. There are a total of 6 level connections on the light string, namely: one for power and one for ground, and 4 for data: Ckout / Ckin, OEout / OEin, Lout / Lin, Dout / Din. Ckout / in, OEout / in, Lout / Lin, Dout / Din of the serial drive control chip are connected to Ckout / in, OEout / in, Lout / Lin, Dout / Din on the light beam string; VCC and GND are connected to the power supply and ground wire on the light string; the signal output of the serial drive control chip is connected to B, G, and R respectively.

[0016] Each group of display light bundles is composed of a small circuit board and soldered on it: a red LED light, a blue LED light, and a green LED light, and each light bundle is displayed by a serial drive control chip. , in the light beams composed of them, the azimuth order of the LED lights is R, G, B, form...

Abstract

A color LED lamp bundle string embedded in with serial transmitting - driving control chip includes a red LED lamp, a blue lamp, a green lamp, serial transmitting - driving control chip and resistance. It is featured as using said chip to control lamp display, forming a line of lamp bundle string by a numbers of above said lamp bundle strings, cascading lines of lamp bundle strings for preparing any desired length of rope lamp bundle string.

Description

technical field [0001] The invention relates to an application of LED display, in particular to a color LED light beam string embedded with a serial transmission driving control chip. Background technique [0002] At present, the LED display light string widely used in the market is generally: light-emitting diodes RGB with three colors (R is a red light-emitting diode, B is a blue light-emitting diode, and G is a green light-emitting diode) as a light-emitting point. The basic unit of , that is, a pixel. The RGB pixels are used as the basic unit to form a string of light beams to complete the display purpose. [0003] Due to the low technical requirements, this kind of rope-shaped LED display light string has the following shortcomings: [0004] 1. It can only display whether each color is bright or not, and the length of time for monochrome display. [0005] 2. Single change, no grayscale display. [0006] 3. There is no video output, therefore, images cannot be formed...
