Each pixel in traditional full-color light-emitting diode display screen generally by a red light emitting diodes, blue LED, and a green LED form, be combined into RGB through gray-scale Control to three kinds of colors.Along with the continuous lifting of the public to product quality requirement, some not all roses parts of traditional full-color light-emitting diode display screen are also put forward gradually, mainly show the following aspects:
1, with reference to accompanying drawing 1; Traditional each pixel of colour light-emitting diode display screen is formed by a red light emitting diodes R, a blue LED B and a green LED G; It on geometry triangle; This triangle rule light emitting diode of arranging is installed can make on the display plane and to cause the entire display screen brightness disproportionation even many pits to occur than there not being light emitting diode to distribute in the large area region A.
2, each pixel is formed by a red light emitting diodes, a blue LED and a look light emitting diode in the traditional colour light-emitting diode display screen, the situation that brightness does not reach requirement occurs through regular meeting.
3, traditional each pixel of colour light-emitting diode display screen is formed by a red light emitting diodes, a blue LED and a green LED; In the process of blend of colors, tend to because the colourity error that the primary color wavelength error is brought.
The utility model content
The purpose of the utility model provide a kind of display surface brightness evenly, brightness is higher, light-emitting diode pixel unit and LED display that color saturation improves greatly.
For solving the problems of the technologies described above, the utility model provides a kind of light-emitting diode pixel unit, and said light-emitting diode pixel unit is made up of 4 light emitting diodes of arranged, and said 4 light emitting diodes are positioned at four jiaos of matrix.
As the improvement of the utility model, 4 light emitting diodes that constitute said light-emitting diode pixel unit are to be in the 4th color LEDs between 520 nanometers and 620 nanometers by red light emitting diodes, green LED, blue LED and emission wavelength.

Embodiment
By the technology contents, the structural attitude that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
With reference to accompanying drawing 3; Accompanying drawing 3 is depicted as the utility model a kind of LED display is provided; Said LED display is made up of a plurality of light-emitting diode pixels unit, and said light-emitting diode pixel unit is made up of 4 light emitting diodes of arranged, and said 4 light emitting diodes are positioned at four jiaos of matrix.
The utility model makes the light-emitting diode pixel unit in the LED display on LED display, distribute uniformly cleverly; Because display screen generally is a rectangle; The light-emitting diode pixel unit that is provided with is made up of four light emitting diodes; Its geometry also is a rectangle, can realize that so the very perfect splicing on LED display of light-emitting diode pixel unit reaches the effect of being hard to tell pixel boundary.
Among another embodiment of the utility model; With reference to accompanying drawing 3,4 light emitting diodes that accompanying drawing 3 is depicted as said light-emitting diode pixel unit are to be in the 4th color LEDs X between 520 nanometers and 620 nanometers by red light emitting diodes R, green LED G, blue LED B and color wavelength.
