LCD projector introduction

LCD projectors are high-tech products brought about by the development of liquid crystal technology, lighting technology and integrated circuits. The key technology is the manufacture of LCD panels. LCD projectors use the photoelectric effect of liquid crystals, that is, the alignment of liquid crystal molecules changes under the influence of an electric field, affecting the transmittance or reflectivity of the liquid crystal cell, thereby affecting its optical properties and producing images with different gray levels and colors. .

Today's LCD projectors support resolutions up to 1600 x 1200 (UXGA), use time can be extended to more than 8 hours, have high brightness and high fidelity image colors, and can easily access a variety of video signals. They are small, lightweight, and easy to carry. Makes the development of the projector into a new era.

The underlying technology of LCD projectors - LCD panels has always been the only company with Sony and Epson R & D and production capabilities, after years of development, LCD panel technology is maturing. LCD panel technology has always been dedicated to improving performance and reducing processing costs. In improving performance, it mainly improves light efficiency by increasing the aperture ratio. In addition, micromirror array technology is used to increase the light transmittance of the liquid crystal panel and reduce the pixelization of the display image, so that the image is more delicate. Currently, LCD projectors have reached a very high level in terms of brightness index and image fineness. In addition to high-end cinema products, LCD products maintain a leading edge in brightness for monolithic DLP products in both general-use and low-end high-performance projectors. The manufacturers of LCD projectors are mainly Japanese and Korean manufacturers. There are mainly Sony, Epson, NEC, Sanyo and Mitsubishi.
