Abstract

The utility model relates to a pixel arranging structure of an LED display screen. The pixel arranging structure can effectively improve the image clarity under the situation of not increasing the density of an LED luminescent tube, comprises the surface-mounted three-in-one LED luminescent tube and is characterized in that pixels on the adjacent lines of the surface-mounted three-in-one LED luminescent tube are staggeredly arranged in the row direction, the position of each pixel is positioned between the two pixels of the adjacent lines, the spacing interval between the adjacent pixels on the same line is same and equal to the spacing interval between the pixels of each line.

Description

A kind of pixel arrangement structure of LED display

One, technical field:

The utility model relates to a kind of LED display, especially relates to a kind of pixel arrangement structure of LED display.

Two, background technology:

At present, in existing surface welded LED display screen, each pixel all is a three-in-one surface welded LED luminotron, and pixel all is to adopt rectangular display formula evenly arrange (referring to Fig. 1).As display terminal, be subjected to the LED size restrictions, LED display is compared with LCD, plasma display and is had shortcomings (referring to Fig. 3) such as resolution is low, sharpness is not enough.Present solution has only these means of the picture element density of raising, can cause the cost fast rise and do like this, and the degree that improves is limited.

Three, utility model content:

The utility model provides a kind of pixel arrangement structure of LED display in order to solve the weak point in the above-mentioned background technology, and it effectively improves the sharpness of image under the situation that does not increase LED luminotron density.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of pixel arrangement structure of LED display comprises the three-in-one LED luminotron of surface-mount type, it is characterized in that: the interlacing dislocation on column direction of the pixel on the three-in-one LED luminotron of the surface-mount type adjacent lines is arranged.

Above-mentioned each locations of pixels is positioned at the centre of two pixels of adjacent lines, and the spacing between the neighbor on the colleague is identical, and is equal to the spacing between every capable pixel.

Compared with prior art, the advantage that the utlity model has is as follows:

The utility model can improve the sharpness of three-in-one surface welded LED display screen, under the situation of same pixel density, the crenellated phenomena of image is improved significantly.

Four, description of drawings:

Fig. 1 is existing general three-in-one surface welded LED display panel module structural drawing;

Fig. 2 is a three-in-one surface welded LED display panel module structural drawing of the present utility model;

Fig. 3 is the display result figure of Fig. 1 display screen;

Fig. 4 is the display effect figure of Fig. 2 display screen.

Among the figure, the three-in-one LED luminotron of 1-, 2-pixel.

Five, embodiment:

Referring to Fig. 2, comprise the three-in-one LED luminotron 1 of surface-mount type, different with the general arrangement mode that provides among Fig. 1, the interlacing dislocation on column direction of pixel 2 on three-in-one LED luminotron 1 adjacent lines of surface-mount type is arranged, the position of each pixel 2 is positioned at the centre of two pixels 2 of adjacent lines, spacing between the neighbor 2 on the colleague is identical, and is equal to the spacing between every capable pixel 2.When display image, when the value of the corresponding source images first row pixel 2 of displayed value of the first row pixel 2, the displayed value of each pixel of the second row pixel is the value result of computing mutually of neighbor on value and the line direction of corresponding source image pixels, and the rule of computing can be average or carry out computing according to content.

Referring to Fig. 3, this is the display effect of pixel normal alignment.Because resolution is lower, the edge can produce sawtooth effect.

Referring to Fig. 4, this is the display effect that the utility model pixel is arranged, and has obviously improved the sawtooth effect of image border under the immovable situation of resolution.

Claims
