Description

A kind of dot structure of OLED

Technical field

The present invention relates to a kind of dot structure, relate in particular to a kind of dot structure of OLED.

Background technology

OLED (organic light emitting diode; Be abbreviated as OLED) have big visible angle, good contrast and high response speed, and possess characteristics such as frivolous, power saving; Become the flat-panel monitor of main flow, therefore be considered to the display of a new generation.

The coloured image picture of OLED (organic light emitting diode is abbreviated as OLED) mainly provides through a plurality of pixels, and these pixels have redness, green and blue three sub pixels.The design of dot structure affects the resolution of OLED (organic light emitting diode is abbreviated as OLED).In the prior art; Each pixel has redness, green and blue three subpixels in the display structure of OLED (being abbreviated as OLED); With red, green, blue sequence arrangement, the color of the sub-pixel on each file is identical successively for this three subpixels.In the process of making this traditional display structure; For fear of the colour mixture between the adjacent subpixels; Tend to increase the spacing between adjacent two sub-pixels; But do the useful life that will influence resolution and reduce OLED (organic light emitting diode is abbreviated as OLED) like this.

In view of this, how designing the display structure of a kind of OLED (being abbreviated as OLED), to increase resolution, is the problem that those skilled in the art need solution badly.

Summary of the invention

In prior art; In the OLED (being abbreviated as OLED) that exists; Increase the spacing between two adjacent subpixels in order to prevent between the adjacent subpixels colour mixture takes place, the defective that the resolution that causes reduces the invention provides a kind of dot structure of OLED.

A kind of dot structure of OLED is provided according to invention; Be positioned on the substrate; Dot structure comprises a plurality of pixels, and each pixel is arranged in order by first sub-pixel unit, second sub-pixel unit and the 3rd sub-pixel unit and forms, and first sub-pixel unit has a plurality of red sub-pixel; Second sub-pixel unit has a plurality of green sub-pixels, and the 3rd sub-pixel first has a plurality of blue subpixels.

Preferably, first sub-pixel unit, second sub-pixel unit and the 3rd sub-pixel unit have two redness that are arranged side by side, green and blue subpixels respectively.

Preferably; First sub-pixel unit, second sub-pixel unit and the 3rd sub-pixel unit have four redness, green and blue subpixels respectively; Staggered in twos first, second red sub-pixel file of lining up of four red sub-pixel of first sub-pixel unit; Staggered in twos first, second green sub-pixels file of lining up of four green sub-pixels of second sub-pixel unit; Four blue subpixels of the 3rd sub-pixel unit are staggered in twos lines up first, second blue subpixels file, and first redness, green and blue subpixels file are corresponding, and second redness, green and blue subpixels file are corresponding.

Adopt the present invention, can increase the resolution and the aperture opening ratio of OLED, and can not influence the life-span of OLED through increasing sub-pixel to fill the spacing between the neighbor.

Description of drawings

The reader with reference to advantages after the embodiment of the present invention, will become apparent various aspects of the present invention.Wherein,

Fig. 1 shows the structural representation according to the dot structure of OLED in one embodiment of the present of invention.

Fig. 2 shows the structural representation according to the dot structure of OLED in an alternative embodiment of the invention.

Embodiment

With reference to the accompanying drawings, specific embodiments of the invention is done further to describe in detail.

Fig. 1 shows the structural representation according to the dot structure of OLED in one embodiment of the present of invention.With reference to Fig. 1; Dot structure 1 is positioned on the substrate 10; Comprise a plurality of pixels 20, each pixel 20 has first sub-pixel unit 21, second sub-pixel unit 22 and the 3rd sub-pixel unit 23, the first sub-pixel unit 21 successively and has two redness (R) sub-pixel 211 on X-direction; Second sub-pixel unit 22 has two greens (G) sub-pixel, 221, the three sub-pixel unit 23 and has two bluenesss (B) sub-pixel 231.Therefore; As shown in Figure 1; Redness in the dot structure 1, green and blue subpixels on X-direction with such order repeated arrangement: red (R), red (R), green (G), green (G), blue (B), blue (B), what on Y direction, arrange is homochromy sub-pixel.In the dot structure 1 that designs with this kind mode; Can be in first sub-pixel unit 21, second sub-pixel unit 22 and the 3rd sub-pixel unit 23 through many design one subpixels; To fill the spacing between adjacent two sub-pixel unit; Increase the problem of aperture opening ratio that the spacing between the neighbor causes and resolution reduction with regard to having solved like this because of colour mixture takes place between neighbor, and can be in order not increase aperture opening ratio and resolution and then to influence life-span of OLED.

Fig. 2 shows the structural representation according to the dot structure of OLED in an alternative embodiment of the invention.With reference to Fig. 2, with the same among the embodiment of front, dot structure 1 is positioned on the substrate 10, comprises a plurality of pixels 20, and each pixel 20 has first sub-pixel unit 21, second sub-pixel unit 22 and the 3rd sub-pixel unit 23 successively on X-direction.In the present embodiment, first sub-pixel unit 21 has four redness (R) sub-pixel, 211, the second sub-pixel unit 22 and has four greens (G) sub-pixel, 221, the three sub-pixel unit 23 and have four bluenesss (B) sub-pixel 231.Four redness (R) sub-pixel in first sub-pixel unit 21 is lined up first redness (R) the sub-pixel file 212 and second redness (R) the sub-pixel file 213 for 211 two one group; And certain distance that staggers between first redness (R) the sub-pixel file 212 and second redness (R) the sub-pixel file 213, this distance can be selected as required.Four greens (G) sub-pixel in second sub-pixel unit 22 is lined up first green (G) the sub-pixel file 222 and second green (G) the sub-pixel file 223 for 221 two one group; And the certain distance that staggers between first green (G) the sub-pixel file 222 and second green (G) the sub-pixel file 223, this distance can be selected as required.Four bluenesss (B) sub-pixel in the 3rd sub-pixel unit 23 is lined up first blueness (B) the sub-pixel file 232 and second blueness (B) the sub-pixel file 233 for 231 two one group; And the certain distance that staggers between first blueness (B) the sub-pixel file 232 and second blueness (B) the sub-pixel file 233, this distance can be selected as required.

Continuation is with reference to Fig. 2; First redness (R) sub-pixel file 212, first green (G) sub-pixel file 222 and the 232 corresponding arrangements of first blueness (B) the sub-pixel file, second redness (R) sub-pixel 213, second green (G) sub-pixel file 223 and the 233 corresponding arrangements of second blueness (B) sub-pixel.As shown in Figure 1, the redness in the dot structure 1, green and blue subpixels on X-direction also with such order repeated arrangement: red (R), red (R), green (G), green (G), blue (B), blue (B).What on Y direction, arrange is homochromy sub-pixel.In the dot structure 1 that designs with this kind mode; Can be in first sub-pixel unit 21, second sub-pixel unit 22 and the 3rd sub-pixel unit 23 through design two subpixels files; To fill the spacing between adjacent two sub-pixel unit; Solved the problem that reduces because of the resolution of avoiding the caused OLED of spacing of the mutual colour mixture of pixel between increasing between adjacent two pixels and aperture opening ratio like this, and can not influence the life-span of OLED because of the restriction of processing procedure.

Adopt advantage of the present invention to be: can be through increasing sub-pixel to fill for fear of the spacing between the neighbor that increases of colour mixture each other between the pixel; Can increase the resolution and the aperture opening ratio of OLED like this, and can not influence the life-span of OLED.

In the preceding text, illustrate and describe embodiment of the present invention.But those skilled in the art can understand, and under situation without departing from the spirit and scope of the present invention, can also specific embodiments of the invention do various changes and replacement.These changes and replacement all drop in claims restricted portion of the present invention.
