Invention Description: [Technical Field] The present invention relates to a display device, in particular It is about a transflective display. [Previous technical materials] Due to its thin thickness and power saving features, liquid crystal displays have been widely used in portable electronic computers, digital cameras, projectors and other electronic products. The liquid ββ display is different from the conventional cathode ray tube (CRT) display and the eiectr〇iumjnescence (el) display, which itself contains a liquid crystal display panel that does not emit light, and the transmission type (transmission) Type) is a commonly used liquid crystal display type. The transmissive liquid crystal display includes a backlight mounted on the back of the display panel to control the amount of light passing through the liquid crystal panel. However, this backlight consumes 50% or more of the power consumption = power consumption, which is not conducive to power saving. ❿ In order to improve the above problem, the reflection type liquid crystal display crying is suitable for outdoor or portable display. The reflection $ liquid crystal display has a reflector (reflect〇r) instead of the backlight. The ambient light is reflected from the surface of the reflector. Usually, the reflective liquid indicates = twisted nematic (TN) or super twisted direction °.匕 twisted nematic, STN) two modes. SUPer's reflective liquid crystal display that uses ambient light reflections has a much lower visibility when the surrounding environment is dimmed. The shortcoming of the above-mentioned crystal display is that when the surrounding environment is very bright and the liquid is low, the image cannot be clearly distinguished. In order to improve the quality of the display in a bright environment, it is necessary to increase the amount of light from the back of the 134 material. However, this will increase the power consumption of the backlight and LCD. Furthermore, when the liquid crystal display needs to be directly exposed to sunlight or a light source, the quality of the display is inevitably lowered. For example, when a liquid crystal display screen receives direct sunlight or a illuminating light source, the surrounding image will reflect 'and cannot watch the thousand crying. In order to improve the above problems, the technology of constructing a transmissive display and a reflective display on the same liquid crystal display is a semi-transflective liquid crystal display. Referring to Figure 1, the structure of a conventional transflective liquid crystal display will be described. This transflective liquid crystal display includes a lower substrate! 00, having an insulating layer 11 〇; _ lower electrode 120, located on the insulating layer 110, the lower electrode 12 〇 has a reflective region 122 such as a ru layer and - for example, an indium tin oxide layer The upper substrate _ has an inner surface having a color filter 曰 1 ′ — an upper electrode 140 on the color light-receiving sheet 150 ; and a liquid helium layer 130 disposed on the upper substrate 160 and the lower substrate 1 between.
