Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] figure 2 is a schematic diagram of a sub-pixel with a light-shielding layer formed on the color filter layer according to the first embodiment of the present invention.

[0022] The liquid crystal display panel includes a color filter layer 202, a substrate 204, and a liquid crystal layer (not shown) including a plurality of liquid crystal molecules between the color filter layer 202 and the substrate 204. A plurality of pixels are formed on the color filter layer and the substrate, and the image Display in pixels. Each pixel may include one or more sub-pixels, for example, a pixel is composed of three sub-pixels of red, green, and blue (R, G, B), that is, a pixel includes R sub-pixels, G sub-pixels, and B sub-pixels . in such as figure 2 In the shown first embodiment of the present invention, one of the R sub-pixel, the G sub-pixel and th...

Abstract

Embodiments of the present invention provide a transflective liquid crystal display (LCD) panel and a display having the same. The transflective liquid crystal display panel comprises a plurality of pixels, each pixel including a reflective region, a transmissive region, and a transition region located between the reflective region and the transmissive region. A light shielding layer is provided in at least a part of the plurality of the pixels, and the light shielding layer is provided at a position corresponding to the transition region.

Description

technical field [0001] The invention relates to a transflective liquid crystal display panel and a display with the liquid crystal display panel. Background technique [0002] Transflective liquid crystal display has low power consumption and strong adaptability to ambient light. It is currently a relatively active flat panel display technology and is widely used in mobile display devices such as mobile phones and PDAs. Transflective LCDs can display images in both transmissive and reflective modes individually or simultaneously, so transflective LCDs can be used in any ambient light. The basic structure of the transflective liquid crystal display is to divide each R, G, B sub-pixel unit into two parts, the transmission area and the reflection area, so that the liquid crystal in the transmission area works in the transmission mode, and the liquid crystal in the reflection area works in the reflection mode. Its working principle is: when the ambient light is dark, the backli...
