Key technologies

1 . LCD screen secondary cutting technology

In some special applications,conventional dimension and proportion of the LCD screen has been unable

to meet the application demand,so the profiled LCD screen with special size and resolution has been

needed shaped more and more, the second cut technology of the LCD screen has become an important

technology in defense and civilian display equipment.Our company has sophisticated LCD second cut

technology platform that can be tailormade according to customer requirements,the products have

been widely used in the field of military aviation and outdoor display equipment , products has high reliability.

The following figures are the figures of the LCD screen before and after cutting.

2.Optical bonding technology

The working principle of this technology is that the design in shock and vibration resistant of the LCD panels

start from increasing stiffness and damping, isolate vibration through the liquid adhesive,and reduce vibration

and shock energy of the tempered glass transmitted from the system with its damping,while the strengthening

glass share the most of the energy using its stiffness and strength to reduce the stress transferred from system

to the LCD screen and reduce strain on liquid crystal panel,thereby greatly increasing the mechanical resistance

properties of the liquid crystal panel,the optical chart with optical bonding or not corresponding graph is shown in following figure.

Optical bonding technology not only greatly improves the LCD panel's anti-vibration performance , but also prevents the LCD panel from dust and moisture, and can greatly improves the anti-reflective and other optical properties to achieve glare visibility. The anti-reflection effect of the LCD panel after bonding is shown in following figure.

3 High brightness backlight technology

LED Backlight type: side backlight(1,2,4sides), bottom backlight and other assembly Highest brightness :reach 2000cd/m2 and can reach 20000cd/m2

at some special military occasions. The products have been widely used in military airborne, vehicular and other

occasions, its good stability and high reliability has been highly praised by the military.

Optical emission distributed simulation for single LED is shown in following figure.

Optical emission distributed simulation for side backlight is shown in following figure.

Figure of LED side backlight is shown as follows.

Figure of LED bottom backlight is shown as follows.

4 Image board design technology

1 ) Display drive technology

Our display device sizes ranging from 0.9 inch to 56 inch, the resolution from 480 * 480 to 3840 * 2160 , apply a variety of

display drive technology, mainly contain following technologies:

a) Traditional display drive technology

The image drive chips are stocked from mainstream manufacturers, including Genesis, PIXworks etc. ,and the image drive is self-design, with the display resolution from 640*480 to 1920 *1080.products widely used in vehicular, shipboard and other military areas as

well as outdoor display equipment and other civilian areas.

b) Independent research display drive technology

Ø Ø Standard display drive

Due to the processing capacity of dedicated image processing chip in the current market is limited, the highest resolution can only

reach 2560*1600,there is no available dedicated image chip to achieve higher resolution for image drive display.Through independent

research,our company uses FPGA to achieve ultra-high resolution LCD drive technology with resolution of 3840*2160,becoming the only one manufacturer successfully researching this resolution

LCD drive technology. The product has been successfully applied to some national key projects with high reliability, has been highly

praised by customers and the military.

Ø Ø Special display drive

For some special size display timing requirements in military aviation field,we use FPGA to achieve 480*480,600*600 resolution and other

drive display technology of shaped display equipments. At present the both equipments has been successfully applied in military aviation

systems.We can design special resolution display equipments according to customer¡¯s demand.

Figure of standard image drive board is shown as follows.

Figure of super-resolution image drive board is shown as follows.

2 ) Mainboard Technology

Our company has reseached a variety of 6U series CPCI mainboard with X86 architecture, compatible

with PICMG2.0 Rev.3.0 standard. CPU useing INTEL and other mainstream high-performance chips , has the following technical characteristics:

Ø Ø wide temperature operating technology

Ø Ø synchronous three-display technology

Ø Ø complete fault diagnosis technology

Ø Ø low power technology

Figure of one low power consumption mainboard is shown as follows.

5 General technology

Our main general technology levels are as follows:

a)EMC design technology. Our company has rich experience in EMC design, a variety of military equipments in our company has successfully

passed the GJB151 assessment requirements, especially the large size display device successfully passed the electromagnetic

compatibility qualification tests of army ground equipment, solved a recognized national technical problem that the oversized ground

display device is difficult to pass the electromagnetic compatible tests.

b) High-strength, light-weight structural design technology.

c) Universal display reinforcement technology satisfying the military requestment.
