Embodiment Construction

[0026] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] refer to Figure 8 A conventional pixel electrode unit 10 includes red sub-pixels 10R, green sub-pixels 10G and blue sub-pixels 10B arranged in rows. The green sub-pixel 10G has a green pixel main area 11G and a green pixel auxiliary area 12G, the red sub-pixel 10R has a red pixel main area 11R and a red pixel auxiliary area 12R, and the blue-green sub-pixel 10B has a blue pixel main area. area 11B and blue pixel auxiliary area 12B. The red sub-pixel 10R, the green sub-pixel 10G and the blue sub-pixel 10B of the pixel electrode unit 10 all adopt an 8-domain design, thereby improving the color difference. However, in order to realize the 8-domain design, it is necessary to increase metal wiring and capacitance, etc., resulting in a decrease in the aperture ratio of the pixel.

Abstract

The invention discloses a pixel electrode unit and a display panel. The pixel electrode unit (100) comprises a red sub-pixel (100R), a green sub-pixel (100G) and a blue sub-pixel (100B), wherein the red sub-pixel (100R), the green sub-pixel (100G) and the blue sub-pixel (100B) are arrayed in sequence. The green sub-pixel (100G) has a green pixel main area (101G) and a green pixel auxiliary area (102G), and the blue sub-pixel (100B) only has a blue pixel main area (101B). According to the pixel electrode unit, eight-domain low-color-shift design is carried out in terms of the green color which human eyes are sensitive to, four-domain low-color-shift design is carried out in terms of the blue color, and therefore the aperture ratio is improved, and the color shift and the aperture ratio are balanced.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a pixel electrode unit and a display panel. Background technique [0002] At present, types of flat panel displays roughly include liquid crystal displays (LCD: liquid crystal display), plasma displays (PDP: plasma display panel) and OLEDs (organic light-emitting diode, organic light-emitting diode). Among them, the liquid crystal display mode of the liquid crystal display mainly includes an in-plane switch display mode (IPS: in plan switch) and a vertical alignment display mode (VA: vertical alignment). [0003] For vertically aligned display modes, such as Figure 4 and Figure 5 As shown, the liquid crystal display includes a first substrate 11 , a second substrate 12 and a negative liquid crystal 14 disposed between the first substrate 11 and the second substrate 12 like a sandwich biscuit. A common electrode 15 is formed on the first substrate 11; a pixel ...
