Problems solved by technology

In addition, the formation of a normal image (such as an image of uniform brightness) requires that the light from the fluorescent tube is uniformly distributed on the LCD surface and the direction is basically perpendicular to it, but this requirement makes the display thicker and unsatisfactory

Embodiment Construction

[0027] One or more specific implementations of the technology are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described herein. It should be recognized that in the development of any of these actual implementations, as in any engineering or design project, in order to achieve the developer's specific objectives (which vary from implementation to implementation), such as compliance with system-related and business-related constraints , many implementation-specific decisions must be made. Moreover, the development process might be complex and time consuming, but nonetheless would be a routine design, tooling, fabrication undertaking for those of ordinary skill who would have the benefit of this disclosed invention.

[0028] Embodiments of the present invention use a liquid crystal display (LCD) with a modified backlight reflector. The reflectors include sloped reflectors, such as triangul...

Abstract

The embodiment of the invention provides a backlight illuminating system, a video display system and a correlation method, wherein the backlight illuminating system comprises: a light source, which provides illumination for the display system and comprises at least two luminous devices; and a multi-reflector system positioned behind the light source, which is used for reflecting part of light emitted by the light source for a plurality of times so as to increase the transmission paths of the part of the light. By using the technical proposal provided by the invention, the transmission paths of part of the light from the light source can be increased before the light reaches a scattering plate, thus the thickness of an LCD can be reduced.

Description

technical field [0001] The invention relates to the field of video display, in particular to the backlight illumination of video display systems such as liquid crystal displays (LCDs). Background technique [0002] This section is intended to introduce reviewers to various aspects of technology related to aspects of the invention described below. Discussion of related art is believed to be helpful in providing background information to the reviewers, so that the reviewers can better understand all aspects of the present invention. Accordingly, these statements should be reviewed in light of the invention and not as admissions of prior art. [0003] Backlit displays, such as liquid crystal displays (LCD panels), are used in a variety of display systems. These systems include computer flat panel monitors, portable computers, digital cameras, cellular phones, handheld devices, flat panel TVs and digital watches. The LCD panels in these systems contain a matrix of transistors...
