Q1: What is blue light?

A1: Generally, the wavelength of light between 780-380nm are the common visible light that we see. The Blue light which is between 480-390nm is the shortest in wavelength and carries the highest energy one among all visible light waves; it cannot be absorbed by the cornea and crystalline lens, therefore it directly affects the retina and results in direct damage to the eyes.

Blue light exists in the light generated from all type of electronic displayers. Long-term exposure under the blue light could induce macular chronic injuries, eye fatigue and soreness. Possibility of severe myopia, cataract, glaucoma, and other eye related diseases will be increased accordingly. Studies in Harvard University have shown that blue light will confuse the biological clock, thus reduce sleep quality, and raise the possibility of cancer occurrence.

 


Q2£º Why the modern LCD TV/Monitor is more fragile than the traditional CRT? Does it really requireadditional protection£¿
A2£º LCD TV/Monitor appeals to consumers by its characteristics of lightness, thinness, and not occupying big space. It requires precise producing processes on all aspects. The outer panel of LCD is made by 0.2~0.3mm Polarizer with 0.7mm Color Filter and 0.8mm’s ITO Glass.
These constituent parts are fragile and they are indeed not able to have self-protection from being scratched, punctured, and external force impacted etc. Especially when playing with the lately most popular Wii, people might easily skip the controller out of hands thus hit the LCD screen. When the LCD screen is damaged, it has no option but to change the whole panel and the screen panel is the most valuable component of the whole LCD TV/Monitor – it occupies at least 70% net cost of the whole product. If without a proper protection -- the larger the LCD TV/Monitor is, the higher relative damage risk it will have. Therefore, to choose a good LCD TV/Monitor screen protector to guard your fragile LCD TV/Monitor is definitely a desperate must.

Q3£º Will the screen’s visual image be spoiled if we install the protector£¿
A3£º There are two major protector materials in the current market – “Ordinary translucent acrylic” and “Anti UV/Glare translucent acrylic”.
The “Ordinary translucent acrylic” is cheaper because it is integrated with downgrade recycled materials so that the panel’s pureness degree and the anti-impact strength are worse. Besides, because it does not have any Anti Glare/UV optical treatment, the visual effects easily become twisted or deformed caused by the reflection from the protection panel.
Wistech’s screen protectors are 100% with “Anti UV/Glare PMMA (translucent acrylic)”. Other than its high safety anti-impact degree for a better protector, it is with additional protection from Anti-Glare and Filtering-UV. LCD TV/Montior’s brightness is three times higher than traditional CRT.
Wistech’s screen protector can effectively mitigate eyes’ fatigue and blocks 80% invisible UV which is harmful to people’s eyes and skin.

Q4£º Will the screen’s visual image be spoiled if we install the protector£¿
A4£º LCD TV’s light comes from the backlight modular’s CCFL (Cold Cathode Fluorescent Lamps) which is a kind of low pressure mercury fluorescent light. The low pressure mercury gas discharges electricity to generate ultraviolet rays then the UV rays excite the fluorescent powder so that the visible light is produced. That is, the LCD TV/Monitor’s original light comes from the UV rays.
The warning from the Department of Health: people long-term exposing in the enviroment of UV rays are more easily to have caught the skin cancer, cataract, and damage of immune system.

Q5£º Will the LCD TV/Monitor’s appearance or structure be spoiled if I install the protector?
A5£º There are varied brands protectors in the current market. Some of them are made with glass material. Since glass is heavy, it requires additional external hanging tools or technician to install so that it is relatively expensive and inconvenient. Some of them are so-called “built-in type” with thin PC panel less than 1mm but it requires fixing brackets to be adhered to the sides of the LCD TV/Monitor; it ruins the stylish looking of the
LCD TV/Monitor, yet providing “anti-scratch” protection only – not able to guard the fragile LCD/ TV/Monitor from outside force puncture or impact.
It cannot offer complete protection at all. Wistech’s Anti-UV & Anti-Glare series are using advanced frameless patented (patented in Taiwan) streamlined design. It is pity and facile and fits all brand’s LCD TV/Monitor with easy installation; no any extra tools, hanging fixers, or assistance required. So, no worry at all that it will spoil your beautiful LCD TV/Monitor.

Q6£º If I install the protector, will my LCD TV/Monitor be damaged due to poor heat sinking?
A6£º Normally the required working temperature is under 60¡æ ex-factory for LCD TV/Monitor. The average surface degree is under 40¡æ from sold TV/Monitor in the current market. If the screen protector does not have good or special design to sink the heat, it might happen that the LCD TV/Monitor’s surface temperature will rise to the safety upper limit and further to liquidize the liquid crystal thus to generate color deviation.
Wistech’s Anti-UV/Anti-Glare protector series are equipped with unique heat-sinking convection design. It has passed the strict reliability test.
Even sealed the LCD TV/Monitor in the sever 36¡æ environment, after installing our protector, the LCD TV/Monitor’s surface temperature still keeps under 48¡æ. It proves that it is 100% safe to use our screen protectors; no safety concern at all to use Wistech’s screen protectors.
