This invention discloses a thin film encapsulation method, which applies a PECVD method, deposition thin film on the device surface to separate the devices active area from the water vapor and oxygen in the air, so as to realize the physical protection and thus to accomplish the device encapsulation, specifically, comprising the following procedures: (1) Placing the devices to be encapsulated in the PECVD chamber, and fixing the mask to control the encapsulation area; (2) Depositing the inorganic layer, the polymer layer and the graded composition layer by using the organic silica precursor through the PECVD method under the plasma condition and obtain the required encapsulation structure.

A 32 in RGB LED backlight unit is developed. A local dimming algorithm is designed for the backlight, and grid-noise artifacts in the LC driving signal are successfully removed with consideration of the backlight distribution to provide identical intensity from each LED block. The 32 in RGB LED backlight LCD display has achieved a static display contrast of over 20000:1 and an average power reduction of 30%. We have also obtained the color gamut transformation matrix for transferring a cold cathode fluorescent lamp BLU LCD display gamut system to our RGB LED BLU LCD display gamut system, and extended the color saturation by suppositional color expansion method. As a result, the color has been accurately reproduced in RGB LED BLU LCD display with more richness and more saturation. © 2010 Elsevier Ltd. All rights reserved. Source
