Characteristic

 

Using 0509 size LED chip and 1152 zones synchronized with WG Tech's self-developed glass diffuser plate on 27 inch backlight plate to realize the industry's first 0OD glass-based Mini LED backlight plate.

27-inch glass-based Mini LED light plate with 1152 zones, to achieve ultra-high HD quality, can show more details of the visual.

The photolithography process improves the circuit precision of the substrate, allowing the use of smaller LED chip size such as 0509, further reducing the cost of the product and expanding the product market share.

With self-developed glass diffuser plate, the optical mixing distance is greatly reduced to achieve the effect of 0 OD, which can make the backlight plate and whole BLU product thinner and lighter.

OD mixing distance, refers to the distance from the backlight plate to the diffusion plate, when the mixing distance is smaller, Mini LED light-emitting chip light-emitting area is smaller, so that the screen halo can be effectively eliminated. At the same time the use of WG Tech's thick copper-plated glass substrate enables the use of smaller LED chip such as 0509 LED chip, composed of high zoning 1152 zoning, but also to avoid the traditional large-size LED dynamic backlight caused the phenomenon of glare between the bright and dark areas, when staring the monitor with 0OD glass-based Mini LED backlight will not have a sense of stinging in the eyes.

Through the glass diffuser plate and the glass-based backligt plate affixed to realize the mixing distance of nearly 0mm 0OD glass-based Mini LED backlight plate structure with the thickness of only 1.3-1.4mm can achieve the effect of not only thin and light, but also effective control of halo and use of less optical films. 0OD glass-based backlight plate and glass diffuser plate stacked combination of mixing distance is smaller, halo compression is quite excellent, the main body of the screen edge of the no overflow stroke, especially in the dark area of the picture.

Unlike other substrates that will get hot when used for a long period of time or when the power is too high, and the use of which will lead to warping or unevenness of the backlight plate and unable to support the 0OD structure. Due to the physical properties of the glass itself that are easy to dissipate heat, the glass substrate will not encounter the problem that will lead to backlight plate warping or unevenness of the substrate when stacked on top of the glass.
