Problems solved by technology

[0003] To achieve high brightness of the LCD module, in addition to increasing the brightness of the backlight, the only way is to increase the transmittance of the optical film system in the entire LCD module and make full use of light energy. This inevitably requires increasing the number of components of the optical film system. In addition, there must be optical filters that meet the requirements of night vision compatibility, and numerous optical film components bring difficulties to anti-vibration and anti-humidity

Embodiment Construction

[0024] refer to figure 1 , use a film sticking machine to stick the DBEF film (1) on the double-sided anti-reflective glass (2) evenly, and no air bubbles and sundries should enter;

[0025] refer to figure 2 , use the same method to compound two pieces of BEF film (4) on two pieces of double-sided anti-reflective glass (5, 6), pay attention to the prism side of the BEF film facing upward, and ensure that the direction of the two pieces of mirror prism is vertical after compounding ;

[0026] refer to image 3 , compounding two diffusion films (8, 8 ') on the infrared cut filter (9);

[0027] Finally follow Figure 4 Glue the above four pieces of composite film together in sequence and seal them with sealing glue.

[0028] If bubbles are encountered during the compounding process, the bubbles can be removed under high temperature and high pressure with a defoaming machine.

[0029] The manufacturing method of the composite film system is carried out according to the fol...

Abstract

The invention relates to composite optical films and a preparation method thereof, which comprises the following steps: combining a piece of DBEF (dual brightness enhancement film), two pieces of BEFs (brightness enhancement film) and two pieces of diffuser films on anti-reflection glass or an infrared cut-off filter by using optical double side adhesive; reprocessing and sealing the composite films in a certain order. The composite optical films not only meet the basic performance requirement of LCD backlight optical films, but also improve the transmissivity and the vibration resistance, humidity resistance and reliability of the films. Besides, the composite optical films accord with the standards of airborne display and night viewing compatibility, and can be used as airborne LCD module with high reliability.

Description

technical field [0001] The invention belongs to the field of optical composite films in electronic display devices, and in particular relates to performance requirements such as improving the brightness of a liquid crystal module (LCD), anti-vibration, anti-humidity and heat, and meeting night vision compatibility in an airborne LCD display module. Background technique [0002] The core display devices of airborne weapons and equipment such as integrated display systems and weapon fire control systems of modern aircraft are mostly LCD display modules. Based on the needs of airborne applications, this component should have high brightness, high definition, high positioning accuracy, and High contrast, high structural strength and high reliability performance are suitable for cross-linking work between the airborne computer and all airborne weapons and equipment, and realize multi-functional comprehensive information display. At present, the difficulty of the airborne LCD displ...
