Problems solved by technology

However, when detecting a solid-color picture (such as full green) for an RGBW display panel, since each pixel has the same polarity, the coupling of the data voltage to the common voltage Vcom is serious, and the monochrome picture will flicker.

Embodiment Construction

[0034] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0035] The present invention describes a display panel in the form of RGBW, which can be used for a screen of a smart phone, a display of a computer, a display screen of a TV, or a display screen of a tablet computer, etc. The display panel can be a liquid crystal display panel (Liquid Crystal Display, LCD) or an organic light emitting display panel (Organic Light Emitting Display, OLED). The present invention is described by taking the liquid crystal display panel 1 as an example.

[0036] see figure 1 , figure 1 It is a schematic diagram of a cross-sectional structure of the display panel of the present invention. The display panel 1 includes a backlight module 10 , a first polarizer 20 , a TFT array substrate 30 , a liquid crystal layer 40 , a color filter 50 and a second polarizer 60 . The TFT array substrate 30 , the liquid crystal lay...

Abstract

The invention provides a display panel. The display panel comprises a thin film transistor array substrate. The thin film transistor array substrate comprises a number of pixel units which are arranged in a matrix, a number of data lines which are used for driving the pixels, a number of scanning lines, first to fourth data test points and first to fourth scanning test points. Each pixel comprises first, second, third and fourth sub-pixels which are arranged in a matrix with two rows and two columns. Each two adjacent data lines are arranged between two columns of sub-pixels. Each scanning line is arranged between two adjacent rows of sub-pixels. Two adjacent sub-pixels of the same color in the same row have opposite polarities. When display panel solid color picture detection is carried out, coupling effects can be offset, and the problem of solid color picture flicker is improved. The invention further provides a display panel solid color picture detection method and the thin film transistor array substrate.

Description

technical field [0001] The invention relates to a thin-film transistor array substrate, a display panel and a method for detecting a solid-color picture by the display panel. Background technique [0002] Display devices, as display components of electronic equipment, have been widely used in various electronic products. A display device generally includes a backlight module, a first polarizer, a thin film transistor array substrate, a color filter and a second polarizer. The thin film transistor array substrate includes a plurality of pixel units. Each pixel unit includes three sub-pixels, such as a red (Red, R) sub-pixel, a green (Green, G) sub-pixel and a blue (Blue, B) sub-pixel. For such an RGB display panel, in order to allow the light to pass through the color filter more fully, the backlight module consumes a lot of energy. In order to overcome the defects of the RGB format display panel, an RGBW format display panel is developed, and each pixel unit in the RGBW f...
