Description

A High Resolution Pixel Arrangement Structure

technical field

The utility model belongs to plane display technology, in particular to a pixel arrangement structure with high aperture ratio and high resolution.

Background technique

Organic electroluminescent display (English full name Organic Light-Emitting Display, referred to as OLED) has the advantages of active light emission, thinness, large viewing angle, fast response speed, energy saving, wide temperature tolerance range, flexible display and transparent display, etc. It is regarded as the most potential new flat panel display technology of the next generation.

In the prior art, the most effective full-color OLED method is side-by-side, that is, red (R), green (G), and blue (B) sub-pixel units are juxtaposed to the pixel The unit becomes a three-primary-color pixel, and each sub-pixel has an independent organic electroluminescent device. By adjusting the color mixing ratio of the combination of the three colors, true colors are generated, so that the RGB three-color organic electroluminescent devices emit light independently to form a pixel.

In order to achieve full-color OLED displays, lamination of WOLED substrates and CF substrates is a widely used technology, but since light passes through CF, there is a large energy loss, resulting in high power consumption of the display. In order to reduce the power consumption of the display, a scheme in which four RGBW sub-pixels form one pixel is generally adopted, but this scheme will lead to a decrease in the resolution of the display.

CN102636894A discloses a liquid crystal display device and a driving method thereof. The LCD device includes an upper substrate, a lower substrate and a liquid crystal layer. A plurality of R, G, B and W color filters are formed at the upper substrate. In the lower substrate, a plurality of R (red sub-pixels), G (green sub-pixels), B (blue sub-pixels), and W (white pixel) sub-pixel. A liquid crystal layer is formed between the upper substrate and the lower substrate. Each pixel is composed of three-color sub-pixels among R, G, B, and W sub-pixels. Pixels containing W sub-pixels in multiple pixels share one color of sub-pixels contained in adjacent pixels and display a color image, specifically the parallel arrangement of RGBWRGBRGBWRGB as shown in Figure 1, wherein every three sub-pixels form a Pixels, a missing color borrows the color sub-pixel of the adjacent pixel, which will cause some pixels to lack an RGB sub-pixel, which increases the difficulty of driving and makes the display appear grainy.

Utility model content

For this reason, what the utility model intends to solve is the problem of difficult driving and poor display effect caused by borrowing adjacent pixels in the OLED full-color scheme, and provides a high-resolution pixel arrangement structure, which can be used without sharing RGB monochrome sub-pixels. High resolution can be obtained at the same time

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows:

A high-resolution pixel arrangement structure, including a plurality of pixel units, the arrangement structure of the pixel units includes at least two rows of pixel units, and each pixel unit includes a red sub-pixel, a green sub-pixel, a blue sub-pixel and a white sub-pixel. Photo sub-pixels, the red sub-pixels and the green sub-pixels of each pixel unit are arranged between the blue sub-pixels and the white sub-pixels, and the blue sub-pixels of the pixel units in two adjacent rows are in the row direction The projections of do not overlap.

The projections of the red light sub-pixels and green light sub-pixels in the pixel unit in the row direction are completely or partially overlapped.

The projections of the red light sub-pixels and the green light sub-pixels on the blue light sub-pixels in the pixel unit do not overlap.

The blue light sub-pixels of the pixel unit overlap with the projections of the white light sub-pixels in the adjacent row in the row direction.

The pixel unit is a square.

The cross sections of the blue light sub-pixel and the white light sub-pixel are rectangular with the same shape, and the cross sections of the green light sub-pixel and the red light sub-pixel are square with the same shape. The length of the long side of the rectangle is greater than twice the length of the side of the square. The short side length of the rectangle is equal to the side length of the square.

Along the column direction, the pixel arrangement structures of two adjacent rows are mirror images of each other.

Compared with the prior art, the above-mentioned technical solution of the utility model has the following advantages:

The high-resolution pixel arrangement structure BGRW provided by the utility model is arranged in the shape of "mouth and mouth", and the blue light sub-pixels and white light sub-pixels in two adjacent rows are arranged alternately, without reducing the aperture ratio of blue light pixels and white light pixels In this way, the spacing between blue sub-pixels and white sub-pixels can be effectively reduced, thereby reducing the area of pixel units, increasing the number of pixel units per unit panel area, and achieving high resolution. Compared with the solution disclosed in CN102636894A, the area of each pixel can be saved by 1/4, and the display brightness can be greatly improved and the display effect can be softened.

In addition, the blue sub-pixels and white sub-pixels in two adjacent rows are arranged alternately, and the projections in the row direction do not overlap. The strength of the mask plate is improved, the problem that the opening is easily deformed by the magnetic field lines and external force is avoided, the utilization rate of the mask plate is improved, and the panel manufacturing cost is reduced.
