Problems solved by technology

Many current privacy filters and films used in laptop computers, display screens, and some mobile devices absorb light, reducing the energy efficiency of the device
Furthermore, these current privacy filters and films are expensive and unwieldy as they interfere with touch screen functionality and must be physically removed to enable wide angle viewing of the display

Embodiment Construction

[0019] Embodiments of the disclosure generally include adaptive backlight modules for displays and methods and systems for manufacturing adaptive backlight modules.

[0020] figure 1 is a system for producing an adaptive backlight module according to one embodiment. The system 100 may include a physical vapor deposition (PVD) chamber 102 , a chemical vapor deposition (CVD) chamber 104 , an emboss / printing chamber 108 and a liquid crystal deposition chamber 106 . According to one embodiment, for the production of the adaptive backlight module, the substrate may first enter the PVD chamber 102 for processing (as described below with respect to Figures 3A to 3C described) or CVD chamber 104 for processing (as described below for figure 2 described). In one embodiment, if the substrate enters the CVD chamber 104 first, the substrate will then directly enter the liquid crystal deposition chamber 106 for processing. If the substrate enters the PVD chamber 102 first, the substr...

Abstract

An adaptive backlight module and a method and system for producing an adaptive backlight module are described herein. In one example, an adaptive backlight module includes a light source, a polarizer,at least one enhancement film disposed between the light source and the polarizer, and a diffuser disposed between the light source and the enhancement film. The diffuser includes a first electrode coupled to a first substrate and a second electrode coupled to a second substrate. A liquid crystal layer is disposed between the first electrode and the second electrode of the diffuser.

Description

technical field [0001] Embodiments of the disclosure generally relate to adaptive backlight modules for displays and methods and systems for manufacturing adaptive backlight modules. Background technique [0002] Backlight units for display devices are usually one of the largest extractors of power consumption, resulting in limited battery life in mobile electronic devices. Usually most of the light exiting the display screen is unnecessary for a single user and is easily seen by non-users within the line of sight. Many current privacy filters and films used in laptop computers, display screens, and some mobile devices absorb light, thereby reducing the energy efficiency of the device. Furthermore, these current privacy filters and films are expensive and awkward because they interfere with touch screen functionality and must be physically removed to enable wide angle viewing of the display. [0003] Accordingly, there is a need for techniques that reduce power consumption...
