Problems solved by technology

The two reflective layers of each FPI modulator on the panel must be kept strictly parallel when driving, any inclination between the reflective mirror surfaces will cause a pixel to display rainbow spots and not work properly
A complete display panel only needs a few defective pixels to make it scrapped. This is the difficulty in the manufacture of analog Fabry color modulator pixels, and it is even more difficult to make industrial information boards or outdoor billboards
However, the traditional LED display consumes a lot of power, and it is difficult to provide the required electric energy through solar energy, so it must be provided by the mains.
Although the power consumption of black and white LCD screen is very low, it is greatly affected by the temperature of the climate, and the scope of application is very narrow

Abstract

The invention relates to a reflective big-pixel bistable-state color display module, which comprises a transparent panel, a backboard, a plurality of movable lenses, supporting pins and electric conductive elastic fixing pieces, wherein a layer of semipermeable reflective film is arranged on the back side of the transparent panel; a transparent layer covers the surface of the semipermeable reflective film; by virtue of the supporting pins, the transparent panel and the backboard are connected; the side, facing the transparent panel, of the backboard is provided with electrodes; the movable lenses are arranged between the transparent panel and the backboard; the side, facing the transparent panel, of each movable lens is provided with a reflective layer; the movable lenses are connected to the transparent layer or connected to the supporting pins by virtue of the elastic fixing piece; the movable lenses get into contact with the transparent layer or the backboard; and the elastic fixing pieces and the electrodes on the backboard are connected to a driving circuit. The display module provided by the invention is simple in structure, convenient to manufacture and relatively low in cost; the display module is low in energy consumption and excellent in performance under outdoor strong light, and the display module is lightly affected by climate and temperature; and two predetermined contrast colors can be implemented at each pixel, so that the combined display of words or patterns is achieved.

Description

technical field [0001] The invention relates to the technical field of color display, in particular to a color reflective large pixel bistable display module. Background technique [0002] Current display screens generally adopt luminescent display screens, which have some defects. People often find themselves unable to see their phone's screen outdoors because the brightness of the display isn't powerful enough to overcome the brightness of the ambient light. The light emitted from the display screen can also cause eye fatigue, especially for children whose eyes are still developing. This kind of luminous screen will cause great damage to children's eyes. [0003] More importantly, taking a mobile phone as an example, when the light-emitting display is always turned off, the liquid crystal display still consumes more than 70% of the power consumption of the mobile phone, and only about 6% of the power consumption of the liquid crystal display comes from the backlight of th...
