XESAME Research, Development and Customized Solutions

Quality arises from details. Reputation driven by technology.

Material selection of XESAME On-cell (high color) and In-cell:


● Top-notch wide color gamut backlight


We are using Quantum Dot LED, a new breakthrough backlight technology. Quantum dots themselves carry light-emitting properties. Quantum dots on a Quantum Dot Enhancement Film (QDEF) generate red light (R) and green light (G) under the illumination of a blue LED backlight, and blend with the blue light (B) that partially transmits through the film to form white light, thereby enhancing the luminous effect of the entire LCD backlight. On the one hand, this technology effectively improves the color saturation of LCD. Compared with traditional wide color gamut technologies, Quantum Dot technology increases the color gamut of LCD by 30% without adding to the thickness of CF film. On the other hand, it can also increase the backlight brightness and reduce energy consumption. With a brightness that reach up to 550 nit and a wider color gamut, the display quality is much closer to the wide color gamut standard of original screens (DCI-P3)

What do 625 nite and DCI-P3 mean?

When looking at a screen, you certainly have never felt dazzled as if you were staring directly at the sun, the brightness of which can reach up to 10 to the 5th power. The spectrum of brightness detectable by a human eye is very expansive, but of course it is not to say that the display of a device should dazzle like the sun. 625 nite is roughly the brightness of a road surface on a cloudy day, which is still a far cry from that of the light reflected by objects on a sunny day.

DCI-P3 is a newer color standard for digital cinema, matching the entire color gamut in films as much as possible. It is not the standard with the widest color gamut (the latest standard being BT.2020), but with wider red and green ranges, it is a notch above the Rec.709 standard. The figure below is for comparison. For a display device, the more colors it displays, the more powerful it is. Whether it shows true images or not has a lot to do with the shooting device and image processing. At least for now, it falls within the spectrum range visible to the human eye.

The display delivers a realistic and more vivid reproduction of colors on the display screens.

● Our choice of tempered glass panels: high-strength aluminosilicate glass

Aluminosilicate glass mainly comprises of silica and alumina, in which the alumina content can reach over 20%. The coordination number of aluminum ions is dependent on the R2O (alkali metal oxide) content. Aluminosilicate glass has good chemical stability, electrical insulation, mechanical strength and low coefficient of thermal expansion. Because of its high viscosity under high temperatures, the material also has a high melting temperature. Aluminosilicate glass has a low expansion coefficient [(30~60) x 10-7/℃] and good water resistance. As the viscosity of the molten glass increases sharply with decreasing temperature, it is suitable for forming glass fibers by spraying. Compared with other glasses, it has a very high softening point.


① Premium hardness with high impact resistance

② High abrasion resistance with a surface not easily damaged

Our high-quality bezels and cold roll laminating process are identical to that of the original assembly. Benefiting from strong adhesion as well as resistance against high and low temperatures, our assembly holds the components together durably.

● Premium high-conductivity, high-quality supplementary materials: we use high-quality flexible printed circuits (FPC)

Advantages: FPC has excellent acid and alkali resistance, oil resistance, heat and humidity resistance that facilitate the cooling of the device. It has higher assembly reliability and quality than traditional circuit boards.

At XESAME, we strive to match the original quality in product manufacturing process and material structure, with an optimized oleophobic coating technology.
