Problems solved by technology

[0003] However, since the transmissive area of ​​the transflective liquid crystal display panel adopts the backlight mode, the light only needs to pass through the liquid crystal layer once; while the reflective area uses external light as the light source, so the light needs to pass through the liquid crystal layer twice
This causes the phase delay of light when passing through the reflective region to be twice that of the transmissive region, making it difficult for the transmissive and reflective regions to obtain the same photoelectric characteristics at the same time

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The present invention can be used in traditional in-plane switching (In-Plane Switching, referred to as IPS) blue phase liquid crystal display mode, fringe field switching (Fringe Field Switching, referred to as FFS) display mode and fringe and in-plane switching (fringe and in-plane switching, referred to as FIS) ) to display the mode. The following embodiments take the traditional in-plane switching blue-phase liquid crystal display mode as an example to illustrate th...

Abstract

The present invention discloses a transflective liquid crystal display panel, including a first substrate, a second substrate and a liquid crystal layer located between the first substrate and the second substrate, and a region between the first substrate and the second substrate is divided into a plurality of transmission regions and a plurality of reflection regions, and thicknesses of the liquid crystal layers corresponded with the transmission regions and the reflection regions are equal, and the transmission region comprises a plurality of first electrodes, and the reflection region comprises a plurality of second electrodes, and an extension direction of the first electrode and the absorption axis of the first polarizer form a first included angle, and an extension direction and the absorption axis of the first polarizer form a second included angle.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a transflective and transflective liquid crystal display panel. Background technique [0002] Liquid crystal display panels are divided into transmissive, reflective and transflective according to different light sources. The transmissive liquid crystal display panel needs to be equipped with a backlight, and the light emitted by the backlight passes through the transparent electrode and the liquid crystal layer to display images; the reflective liquid crystal display panel is provided with a light source by the front light source or the external environment, and the front light source or light from the outside world passes through After the liquid crystal layer, after reflection, it passes through the liquid crystal layer again to display images, that is, the light of the reflective liquid crystal display panel needs to pass through the liquid crystal layer twice; the trans...
