Problems solved by technology

[0013] In addition, in organic light-emitting display devices, the aperture ratio of sub-pixels usually decreases with the increase of resolution, and the final result is that the operating brightness of monochrome devices is increased and the life of the display screen is shortened.

Embodiment 1

[0067] image 3 It is a schematic diagram of the first embodiment of the pixel structure of the organic light emitting display of the present invention. Such as image 3 As shown, the display includes a plurality of pixels 300, and each pixel 300 is composed of a plurality of sub-pixels. Each pixel 300 includes an R sub-pixel area 301 , an R light-emitting area 302 , a G sub-pixel area 303 , a G light-emitting area 304 , a B sub-pixel area 305 and a B light-emitting area 306 . The size of each pixel is H×H.

[0068] In this embodiment, the R, G, and B sub-pixels of each pixel are quadrangular, and the sub-pixels are arranged in the shape of a "pin" or an inverted "pin". Wherein, the length and width of the R and G sub-pixels are both 1 / 2H, and the width of the B sub-pixel is H, and the height is 1 / 2H, that is, the area of ​​the B sub-pixel is twice that of the G sub-pixel or the R sub-pixel.

[0069] Wherein, each pixel unit in this embodiment may be composed of an odd num...

Embodiment 2

[0080] Such as Figure 5 A second embodiment of the invention is shown. In this embodiment, the display includes a plurality of pixels 500, and each pixel is composed of a plurality of sub-pixels. The shape of each sub-pixel is a triangle. Preferably, as Figure 5 As shown, each sub-pixel is an isosceles right-angled triangle, and the right angles of every four sub-pixels are arranged opposite to each other to form a pixel. Four sub-pixels constituting one pixel include one R sub-pixel 501 , one G sub-pixel 503 and two B sub-pixels 502 , wherein the two B sub-pixels 502 are arranged opposite to each other. In this way, the area of ​​the B sub-pixel 502 is also twice that of the R sub-pixel 501 or the G sub-pixel 503, thereby ensuring the display effect of the display.

[0081] Such as Figure 5 As shown, this figure only shows a part of the organic light emitting display, and the number of pixels in the actual product is not limited to this. The first row, the second row...

Embodiment 3

[0092] For Example 2, we can replace some of the color sub-pixels with other colors, such as Image 6 In the third embodiment of the present invention shown, each pixel 600 in this embodiment is composed of an R sub-pixel 601 , a G sub-pixel 603 , a B sub-pixel 602 and a W (white) sub-pixel 604 . This example is compatible with Figure 5 Compared with the illustrated embodiment, one of the B sub-pixels is replaced by a W sub-pixel 604, and the positions of the R sub-pixel and the G sub-pixel are exchanged. The advantage of this embodiment is that since each pixel includes a W sub-pixel, it can display white more purely and achieve higher brightness.

[0093] Specifically, such as Image 6 As shown, the display includes a plurality of pixels 600, and each pixel is composed of a plurality of sub-pixels. The shape of each sub-pixel is a triangle. Preferably, as Image 6 As shown, each sub-pixel is an isosceles right-angled triangle, and the right angles of every four sub-pix...

Abstract

Provided are a pixel structure and an organic light-emitting display using same. The pixel structure comprises multiple pixels, each pixel comprises multiple sub-pixels, at least one pixel forms a pixel unit, pixel units that are longitudinally adjacent are arranged in a vertical mirror manner, and / or pixel units that are horizontally adjacent are arranged in a horizontal mirror manner. Through a reasoned structure of pixel arrangement and by deposition of sub-pixels of adjacent pixels through a shared mask aperture, the area of mask apertures can be increased during deposition, the difficulty of manufacture with the mask technique is reduced and the difficulty of the deposition process is also reduced. No gap needs to be reserved when the sub-pixels of the adjacent pixels of the mask are deposited, and genuinely high PPI can be achieved while maintaining a high aperture ratio. In addition, mask strength is increased, thus preventing deformation during use, improving product yield, increasing service life and reducing costs.

Description

technical field [0001] The present invention relates to the field of organic light-emitting display technology, in particular to a pixel structure and an organic light-emitting display using the pixel structure. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) is an active light-emitting device. Compared with the traditional LCD (Liquid Crystal Display, liquid crystal display) display method, OLED display technology does not require a backlight and has the characteristic of self-luminescence. OLEDs use very thin layers of organic materials and glass substrates that emit light when an electric current passes through them. Therefore, OLED displays can significantly save power, can be made lighter and thinner, can withstand a wider range of temperature changes than LCD displays, and have a larger viewing angle. OLED display is expected to become the next-generation flat panel display technology after LCD, and it is one of the mos...
