Abstract
The present invention discloses a four-light arranging method based on four basic color LEDs and used for LED display screens, wherein which is characterized as follows:each LED is homogeneous and are in well-regulated equidistance distribution; the entire display screen consists of RGBW square matrixes in arrangement, in consisting elements of the square matrix, the orientation sequences are in turn that R is at the top left side, G is at the top right side, B is at the left lower side and W is at the right lower side, at the same time the four adjacent LEDs with equal appearing intervals constitute RGBW square matrixes which are used as basic cells, are unrolled and arranged at the display screen. Said arrangement manner preferably resolves the problem of displaying brightness of the existing display screens and remarkably resolves the dissipating heat problem; at the same time, due to the adoption of the four-color four-lamp arrangement method, the color revealing capability of images is greatly improved, and the display screens achieve high displaying effects.
Description
Technical field
The present invention relates to a kind of LED display, the arrangement method of the light emitting diode on particularly a kind of four look LED display.
Background technology
The LED display of institute's widespread use in the market, arranging of its light emitting diode is commonly: the plug-in type light emitting diode RGB (R is that red light emitting diodes, B are that blue luminescent diode, G are green LED) with three kinds of colors closely condenses together, mutual spacing is close to zero, base unit as a luminous point, i.e. pixel, thus reach white balance.This rgb pixel is for evenly distributing on display screen substantially, so that integral body reaches the demonstration purpose.
The diode arrangement of this LED display has the following disadvantages:
1, the diode spacing in the rgb pixel is too small, causes the LED heat radiating poor-performing, thereby influences the performance of whole display effect and equipment.
2,, in the imaging process of colour, be very easy to make whole screen colourity inhomogeneous because the diode spacing in the rgb pixel is little.
3, because RGB only forms an imaging point, for high-resolution requirement, the quantity that can only increase RGB solves.
4, because RGB forms an imaging point, be subjected to the quality influence of LED, caused the uneven of LED screen practical application effect and sense organ brightness.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art part, by increasing white light-emitting diode and the arrangement method of luminance dot spacing from a kind of four look diodes that provide being provided.
