Wide-angle supermicro penetration reflective vertical directional liquid crystal display

Abstract

The penetrating reflective vertically configured LCD has partial penetrating pattern formed in the supermicro reflecting layer, and the supermicro reflecting layer is also used as the lower electrode and has scattering effect to form penetrating reflective structure with excellent reflecting effect. The present invention has simple manufacture process and low manufacture cost. The lower electrode with opening pattern corresponds to the upper transparent electrode with openings so as to separate display unit into several regions in cut domain structure. By means of matching with vertically configured liquid crystal molecules, the LCD has wide view angle.

Description

technical field [0001] The present invention relates to a plane display device, and in particular to a transflective type liquid crystal display (LCD) with a wide viewing angle. Background technique [0002] For a long time, liquid crystal displays have been widely used in digital electronic products such as electronic watches and computers. With the continuous development and progress of thin film transistor-liquid crystal display (TFT-LCD) technology, coupled with its advantages of small size, light weight, low driving voltage, and low power consumption, it has been widely used in notebook computers, Personal digital processing system, and color TV, and gradually replace the traditional bulky cathode ray tube (CRT) display. [0003] In the development of liquid crystal displays, at the beginning, the main axis of development was the transitive type liquid crystal display. Generally, for a transmissive liquid crystal display, the light source is built into the back of the...

Problems solved by technology

Generally, the complex refractive index Δn of the reflective liquid crystal molecules is about 0.06-0.1. If the gap change Δd is 0.5-1.5 μm, the change of Δnd (Δnd j -Δnd i ) is about 0.06-0.15μm, resulting in too low reflected light efficiency, ranging from the ideal 100% to 60-85%, unable to effectively reflect the surrounding light source to the user's eyes, resulting in poor display effect of the display good

Therefore, traditional transflective LCDs are difficult to be applied to portable display devices, such as mobile phones, personal digital assistants (PADs), notebook computers, portable TVs, etc.
