Abstract

The present invention belongs to the LED display screen technology and principally relates to a 3-lamp arrangement method for a 3-basic color LED. The arrangement is characterized as follows: each LED is homogeneous and are in well-regulated distribution; the entire display screen consists of RGB triangles as basic cells in arrangement, in consisting elements of thereof, 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 lower side, at the same time at the display screen, three adjacent LEDs constitute RGB triangles which are used as basic cells, are staggered homogeneously, unrolled and arranged well-regulated at the display screen. Said arrangement manner resolves the difference of cost of products caused by the LED material quality of the existing display screen, better resolves the dissipating heat problem at the same time, and greatly reduces the material cost with improved displaying effects. This is an outdoor LED display screen application scheme with modern techniques and is worth extending.

Description

The three lamp bank cloth methods of three kinds of Essential colour LED

Technical field

The present invention relates to a kind of LED display, specifically, relate to the arrangement method of the light emitting diode above a kind of LED display.

Background technology

The LED display of institute's widespread use in the market, arranging of its plug-in type light emitting diode is commonly: the plug-in type light emitting diode RGB (R is that red light emitting diodes, B are that blue LED, G are green LED) with three kinds of colors closely condenses together, mutual spacing is close to zero, elementary cell as a luminous point, i.e. pixel, thus reach white balance.With the rgb pixel is that elementary cell evenly distributes on display screen, so that integral body reaches the demonstration purpose.

The diode arrangement of this kind 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, because the diode spacing in the rgb pixel is little, cause in the imaging process of colour, be very easy to make whole screen colourity inhomogeneous, whole display resolution is low relatively, makes display effect can not use up people's will.

3,,, can only solve by the quantity that increases RGB for high-resolution requirement because RGB only forms an imaging point.

4, because the kind difference of diode, price variance is bigger, have in addition differ tens times, when having increased production cost, can not ensure display effect well.

Summary of the invention

The objective of the invention is at the deficiencies in the prior art, by the arrangement method of luminance dot spacing from a kind of novel diode that provides is provided.

For realizing described purpose, the diode arrangement mode above the LED display of the present invention is: during the LED in LED display (light emitting diode) two dimensional surface was arranged, the even rule of each LED equidistantly distributed.Entire display screen is made up of as elementary cell is evenly distributed the RGB triangle, and the RGB triangle is made of three LED, and each individual square formation reaches white balance.In the arrangement of component, the upper left side is R (red light emitting diodes), and the upper right side is G (green LED), and the below is B (blue LED), and we are called the RGB triangle.Its location expression is followed successively by upper left side, upper right side, below in proper order, and is as follows.And on display screen, three adjacent LED constitute the RGB triangle; And spread out on display screen for elementary cell according to this.

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 optical 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; Also can be equal to fully by the piece-shape type light emitting diode alternative, various types of light emitting diodes that it comprises on the market and exists in theory, and the various light emitting diode that can be used as other class of demonstration.

Adopt diode arrangement method of the present invention, will make being evenly distributed of plug-in type diode, avoided concentrated arranging in the past to cause the deficiency of poor heat radiation; Simultaneously because being evenly distributed of diode, we can make the brightness of each monochromatic luminous point (red, green or blue) all can independently regulate and control, compare with LED display in the past, this technology can ensure that more whole screen is having better effect aspect color and luster, brightness and the consistance.And, produce virtual pixel, thereby increased the quantity of imaging point with the pixel overlapping sampling that is close to because the sampling of videl signal is based on three pixel pointwises samplings.Adopt this arrangement method, owing to the increase of imaging point, improved the density of pixel, its image restoring ability is stronger, thereby obtains the more image of high-res.

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.

Embodiment

The LED arrangement mode of the three lamp bank cloth methods of three kinds of Essential colour LED of a class as shown in Figure 7 is to be formed by the combination of RGB triangle.

The arrangement mode of RGB triangle individuality is: in the arrangement square formation of component, the upper left side is R (red light emitting diodes), the upper right side is G (green LED), and the below is B (blue LED), and we are called the RGB triangle according to order upper left, upper right, the below.Fig. 3 promptly is the synoptic diagram that the RGB triangle is arranged.

In present technique, the behind of display screen is the electronic circuit control technology.The monochromatic luminous point of its each on display screen (R, B or G) can independently be a point all, compares with technology in the past, can guarantee that more whole screen effect aspect color and luster, brightness and consistance is better.

As shown in Figure 7,1R1G1B constitutes a real image vegetarian refreshments among the figure, promptly among the figure ●; Any three adjacent lamps all can constitute a virtual representation vegetarian refreshments, comprise ●, two kinds of ◎.

Therefore, the content that the real image point of fixed qty is shown, if by this arrangement method, along with the increase of imaging point and the increase of density, reducing power strengthens, and makes display effect more true to nature.

Simultaneously, in this invention, the RGB triangle can be equal to alternative by arbitrary triangle in RBG triangle, GRB triangle, GBR triangle, BGR triangle, the BRG triangle fully.
