Problems solved by technology

Even if the thinnest evaporation mask is used, the current PPI still cannot be greatly improved, and the use of the thinnest evaporation mask will cause its width to fail to maintain the original level, which will lead to a decrease in product yield.

Embodiment 1

[0053] A display panel comprising a matrix structure in which sub-pixels of three different colors are arranged, wherein two sub-pixels of the same color are used as a combination, and the combinations of three different colors are arranged in sequence in the row direction, and in two adjacent rows Combinations of the same color are set at staggered positions by one or three sub-pixels.

[0054] It should be noted that in the embodiment of the present invention, the combination of pixels of different colors in adjacent rows may be arranged in a manner of staggering an odd number (such as one or three) of sub-pixels, so as to achieve a better color mixing effect. Wherein, the combination of pixels of different colors in adjacent rows is arranged in a manner of staggering the positions of three sub-pixels, so that the distribution of sub-pixels of various colors in the entire display panel is more uniform, thereby achieving a better display effect. For example, the three differe...

Embodiment 2

[0073] This embodiment provides a display panel. Compared with the display panel in Embodiment 1, the relative positions of the sub-pixels in the same pixel unit are different.

[0074] In this embodiment, the same as Embodiment 1, the two sub-pixels in each column of the pixel block are of different colors; two adjacent sub-pixels of the same color in the row direction are used as a combination, and one of the rows of the pixel block is Combinations of three different colors are arranged in sequence, and the other row of the pixel block is arranged adjacent to the combination of two colors, and the two sub-pixels of the third color are located on both sides of the two combinations. Different from Embodiment 1, in order to increase the uniformity of light mixing, in this embodiment, columns are formed by staggering half of the sub-pixels.

[0075] like Figure 8 As shown, among the three sub-pixels in the same pixel, the sub-pixel in one row is in the middle of the two sub-pi...

Embodiment 3

[0079] A display device includes the display panel of Embodiment 1 or 2.

[0080] The display device can be any product or component with a display function such as electronic paper, OLED panel, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, navigator, etc.

[0081] Embodiments 1-3 provide a new type of display panel, in which two adjacent sub-pixels in the row direction have the same color, so that when the pixel unit is prepared using an evaporation mask (FMM Mask), the row side The opening area of ​​the upper two sub-pixels is merged, so that the structure of the mask plate is simple and the difficulty of evaporation is reduced, thereby overcoming the problem that the opening area of ​​the evaporation mask plate cannot be reduced, and the effect of improving the PPI is realized through the evaporation process, and the display of the display device is ensured. While improving the quality, the product yield rate is improved.

Abstract

The invention belongs to the technical field of display, and particularly relates to a display panel, a driving method of the display panel and a display device. The display panel comprises a matrix structure formed by arranging three types of sub-pixels with different colors, wherein every two sub-pixels with the same color serve as a combination, three types of combinations with different colors are sequentially arranged in the row direction, and the combinations, with the same color, in every two adjacent rows are arranged at the interval of one or three sub-pixels. According to the display panel, because every pair of adjacent sub-pixels in the row direction have the same color, when an FMM Mask is used for manufacturing pixel units, opening areas of every pair of adjacent sub-pixels in the row direction can be combined, the structure of the mask can be simplified, evaporation difficulty can be reduced, and then the problem that opening areas of the FMM Mask can not be reduced is solved; the effect of improving the PPI is achieved through the evaporation process, and the yield of products is improved on the premise that the display quality of the display device is guaranteed.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel, a driving method thereof, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device is an emerging flat-panel display device. Compared with Liquid Crystal Display (LCD for short), OLED does not require a backlight because it can emit light by itself, so it is relatively For lower power consumption. [0003] OLED pixel structures in OLED display devices are generally arranged in a matrix. According to different driving methods, they can be divided into passive matrix (Passive Matrix Organic Light Emission Display, PMOLED for short) driving method and active matrix (Active Matrix Organic Light Emission Display, AMOLED for short) drive mode. Compared with the PMOLED pixel structure, the AMOLED pixel structure has the advantages of high resolution and high precision. [0004] A...
