Problems solved by technology

For example, the utility model patent No. 01279604.2 issued by the State Intellectual Property Office of China on September 18, 2002 is called "Long Life, High Brightness and Large Screen Home LCD Projection TV", which realizes the function of high brightness, but it also There are disadvantages, that is, it is large in size and needs to occupy a lot of space, because the optical system in it has only undergone one reflection, so it needs a lot of space to complete the transmission of optical signals

Abstract

The invention relates to a light-path system for projection TV. Wherein, the said TV comprises a shell with an embedded display screen; the light-path system is arranged in the shell, which comprises: a light machine on shell bottom to project the light signal to its first reflector, a third reflector in the shell backside, and a reflection-penetrated lens behind the display to cover some area with a second reflector underside. Wherein, the light signal from said light machine goes through the first and second reflector, the reflection-penetrated lens, the third reflector, and the reflection-penetrated lens till the display. This invention can reduce greatly the TV thickness and volume.

Description

technical field [0001] The invention relates to a projection television, in particular to an optical path system structure of the projection television. Background technique [0002] With the improvement of people's living standards, more and more families hope to have high-definition super-large-screen projection TVs. The current various liquid crystal projection systems are a good way to realize high-definition super-large-screen projection TVs. However, home use requires that the projection system has low-cost and long-life light sources, sufficient brightness, can directly receive TV signals, color performance should reach the level of current TVs, stable performance, and low price of the whole machine. For example, the utility model patent No. 01279604.2 issued by the State Intellectual Property Office of China on September 18, 2002 is called "Long Life, High Brightness and Large Screen Home LCD Projection TV", which realizes the function of high brightness, but it is a...
