The embed serial transmitting driven control chip provides the RGB brightness independent adjustment to each image element and adopts bonging form so that the volume of each image element bulb can reduce and satisfy the art and requirement of the current production.
Description
Technical field
The present invention relates to the application that a kind of LED shows, specifically, relate to a kind of color LED pixel tube of embedded serial transfer drive control chip.
Background technology
The pixel barrel of institute's widespread use in the market, it is commonly: with the light emitting diode RGB (R is that red light emitting diodes, B are that blue LED, G are green LED) of three kinds of colors, elementary cell as a luminous point, i.e. pixel, and form a pixel barrel by plastic packaging, encapsulating.With the rgb pixel tube is elementary cell, forms LED display and finishes the demonstration purpose.
Because this kind pixel barrel is mainly used in LED display, thereby the application of other form is less, and does not have the application that the drive controlling chip is controlled each pixel barrel, has the following disadvantages for the market demand:
1, because be that direct LED drives,, connects complexity, the cost costliness on a large scale so connecting line is many under the long distance applications condition.
2, the data carry electrode is interfered easily.
3, factor to sum up, whole display mode is difficult to realize the video display effect.
Summary of the invention
The color LED pixel tube of a kind of novel embedded serial transfer drive control chip that provides by new designing technique and method is provided at the existing market demand.
In each pixel barrel, by fritter circuit board and welding thereon: some red LED lamp, some blue led lamps, some green LED lamp, serial transfer drive control chip and resistance forms, serial transfer drive control chip is finished the demonstration of this pixel barrel content, be welded in LED lamp on the little circuit board in the pixel barrel, location order is R, G, B, constituting the RGB full color shows, and with the pixel barrel is elementary cell, can finish the cascade of random length, arbitrary shape, any size according to application demand.
Diode used in the present invention, it is the plug-in type light emitting diode, comprise circular inserts formula light emitting diode, semicircle cylindrical inserts formula light emitting diode, oval plug-in type light emitting diode, semicircle plug-in type light emitting diode, oblate plug-in type light emitting diode, and rectangular insert formula light emitting diode, and all installation forms of not enumerating all belong to the light emitting diode of plug-in type.
Adopt LED Application Design of the present invention, it is abundant to make that displaying contents changes, and display effect is beautiful in colour, satisfies the different demands that use in market; By the control and management of serial transfer drive control chip, we can make the brightness of each monochromatic luminous point (red, green or blue) all can independently regulate and control simultaneously, and this technology more can ensure better effect aspect color and luster, brightness and the consistance.And because serial transfer drive control chip in conjunction with the effect of control system, can be taken a sample based on 17000 kinds of colors that computing machine produces, its image restoring ability is good, thereby obtains the image of high definition.
The present invention will be described in detail with reference to the accompanying drawings in conjunction with the embodiments, so that purpose of the present invention, feature and advantage are carried out more deep understanding.
