Embodiment Construction

[0016] Such as figure 1 A type of ultra-small full-color LED display unit embedded with a serial drive control chip is shown. There are 6 level connections on the ultra-small circuit board, namely: one power supply and one ground wire, and four data lines: 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 unit board; VCC of the serial drive control chip and GND are connected to the power supply and ground wire on the unit board; the signal output of the serial drive control chip is connected to B, G, and R respectively.

[0017] Each ultra-small circuit board is composed of several red LED lights, several blue LED lights, and several green LED lights. Each small circuit board has a serial transmission drive control chip to complete the LED light display on it. The order of orientation of the lamps is R, B, G, forming RGB full-color display, and us...

Abstract

The invention relates to a super small colored LED display unit of embed serial driven control chip in the field of the production and technology of LED display apply. It is characterized in that the super small print circuit plate is formed by a serial transmitting driven control chip, a red LED light, a blue LED light, a green LED light and a plurality of resistances; the super small print circuit can finish any amount of serial connecting. The embed serial transmitting driven control chip provides the RGB brightness independent adjustment to each image element and connects the LED light and the driving part on the super small print circuit plate.

Description

technical field [0001] The invention relates to an application of LED display, in particular to an ultra-small full-color LED display unit embedded with a serial drive control chip. Background technique [0002] The LED displays widely used in the market are generally as follows: three colors of light-emitting diodes RGB (R is a red light-emitting diode, B is a blue light-emitting diode, and G is a green light-emitting diode) as the basic unit of a light-emitting point , that is, one pixel. RGB pixels are connected in series to form a light strip to achieve the display purpose. [0003] This strip-shaped LED display decorative light strip has the following disadvantages due to its low technical requirements: [0004] 1. It is formed by connecting a certain length of LED tubes in series, so the whole string of LED lights cannot be adjusted independently. [0005] 2. The whole LED light tube or light strip can be changed by connecting multiple LED light strings (same as abo...
