Problems solved by technology

[0011] However, if using the above figure 1 The liquid crystal display LCD, then owing to there is the limitation that must use polarizing plate 151,172, therefore it is difficult to improve brightness under the situation of using same light source, also use unnecessary parts and optical filter at the same time; And, for There are limitations such as the need to use color filters to form color images

Abstract

The invention relates to a flat board displaying equipment which is used to form designing board and selectively regulate color and quantity of light, in liquid crystal by holograph. Especially, because polarized light is not used, not only reduces expense of quantity of light but also controls light effectively, the lightness can be increased. On the other hand, because the quantity of limb can be reduced, the operation process is simplified, and constructed super slim displaying equipment. Additionally, the utilization factor of light is improved by acting and using the light in light wave channel, and uses light emitting diode LED, laser diode LD as light source, to enlarge chroma recurring range, to construct display equipment with bright picture.

Description

Technical field [0001] The present invention is related to flat panel display devices, and in particular to a flat panel display device that uses holograms to form pattern plates in liquid crystals and selectively adjusts color and light intensity. Background technique [0002] A general flat panel display device is different from a conventional display device using a cathode ray tube CRT in that it forms a screen in a flat form and displays a thin and light clear screen. [0003] Such flat panel display devices usually include liquid crystal display LCD, electroluminescence display ELD, plasma display PDP, field emission display FED and so on. [0004] In the flat panel display device, the most commonly used liquid crystal display LCD has the same figure 1 The structure shown. [0005] That is, the light source 11 is driven to emit light according to the power source driving section 191 that receives power supply from the power source. [0006] The emitted light enters the ligh...
