Problems solved by technology

[0006] However, the aperture ratios of the sub-pixels located around the blank sub-pixel W are not lost, and are obviously larger than those of the sub-pixels located above and below the blank sub-pixel W, which will lead to differences in the aperture ratios of the red, green, and blue sub-pixels. Larger, in the actual display, the color coordinates of the white point will drift, resulting in color shift and affecting the display quality of the screen

Embodiment Construction

[0030] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0031] see figure 2 , the present invention provides an RGBW display panel, comprising a plurality of gate lines 1, a plurality of data lines 2 insulated and intersecting with the plurality of gate lines 1, a plurality of gate lines 1 and a plurality of data lines 2 defines a plurality of sub-pixels arranged in an array, a plurality of TFT T, and a black matrix BM covering the gate line 1 and the scanning line 2; one TFT T corresponds to one sub-pixel arrangement.

[0032] The plurality of sub-pixels includes a plurality of red sub-pixels (not marked), a plurality of green sub-pixels (not marked), a plurality of blue sub-pixels (not marked), and a plurality of blank sub-pixels W. A gate line 1 is provided corresponding to a row of sub-pixels...

Abstract

The invention provides a RGBW display panel. As to a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a blank sub-pixel (W), all of which are adjacent to each other in upper and lower, left and right sides, TFT of the red sub-pixel, TFT of the green sub-pixel and TFT of the blue sub-pixel are all installed in the blank sub-pixel (W). Border of the sub-pixels on both left and right sides of the blank sub-pixel (W) is installed with a kink part (11) to reduce open ratios of the sub-pixels positioned on both left and right sides of the blank sub-pixel (W) and to increase open ratios of the sub-pixels (P) positioned on both upper and lower sides of the blank sub-pixel. Therefore, the open ratios of the red sub-pixel, the green sub-pixel and the blue sub-pixel positioned at surrounding of the blank sub-pixel are adjusted to incline to be consistent. Accordingly, dull of RGBW display panel when displaying with pure color or mixed color is solved, and deviation of coordinate of white flake color is avoided, thereby color error and display quality of pictures being improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an RGBW display panel. Background technique [0002] Both a liquid crystal display panel (Liquid Crystal Display, LCD) and an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel have a plurality of pixels arranged in a matrix. A conventional pixel usually includes three color sub-pixels of red (Red, R), green (Green, G), and blue (Blue, B), and each sub-pixel is controlled by a corresponding thin film transistor (Thin Film Transistor, TFT). The R, G, and B color filters used in the prior art are all absorbing color layers. When light is incident, only the light of the corresponding color can pass through, while the light of the other two colors are all absorbed, making the display The light transmittance of the panel is low. As a result, there has been a display technology that forms red, green, blue, and blank (White, W) four color sub-pixe...
