Embodiment Construction
[0033] The present invention will be further described below in conjunction with drawings and embodiments.
[0034] A novel micro-motor flat-panel imaging device can be produced according to the method of the present invention described below. This micro-motor flat panel display can use light energy more efficiently than liquid crystal display and plasma display. It can also use transparent plastic material as the base plate, so it can be made bendable.
[0035] One aspect involved in the technical solution of the present invention is to use a micro-motor system light switch (micro-motor light switch) to control the light path in the display device. When the light switch is on, the light below it can pass through without loss to reach the observer, and when it is off, the light below it can be completely blocked. In the case of strong external light, according to the present invention, the MEMS light switch can also be used to reflect a small part of light for imaging.

Disclosed are a transmission and reflection dual-use micro-motor optical modulator and flat panel imagescope and a manufacturing method thereof. The optical modulator comprises a light splitter, integrated circuits and light switches, and can be equipped with a color filter and a necessary protective screen. The light splitter is used for leading an incident light uniformly distributed on an incident surface thereof to each of serially separated imaging points, and condensing the light of each imaging point on the incident surface of the light to only occupy a small part of the area of the imaging points. The remaining majority area of the imaging points is used for placing the integrated circuits and the light switches, and for controlling a final direction of the light to achieve control of the color and light intensity of the imaging points. A plurality of methods for designing and manufacturing the optical modulator and the light switches, and an automatic aligned spherical barrel structure used for placing a circular isolated ball on the optical modulator and applied for the light modulator or a general micro-motor structure to be connected with a protective screen thereof and to maintain a fixed distance therebetween are disclosed.
Description
technical field [0001] The invention relates to a transmission and reflection dual-purpose micro-motor optical modulation device, which is especially suitable for flat-panel image display. Background technique [0002] Liquid crystal display (LCD) and plasma display (PD) replaced cathode ray tube display at a very fast speed. The main reason is that the imaging panels of liquid crystal imaging and plasma imaging are much thinner than those of cathode ray tube imaging. However, neither liquid crystal display nor plasma display can utilize energy efficiently. For example, the polarizer used in liquid crystal imaging blocks 50% of non-polarized light, which reduces the utilization rate of light energy by 50%. In the case of equal imaging light intensity, plasma imaging consumes more energy than liquid crystal imaging. There are also many articles and patents about using micro-electromechanical devices as imaging applications. Some MEMS devices, such as Texas Instruments' DL...
