faytech’s sunlight readable LCD monitor is a rugged game-changer in the high brightness LCD market
Nowadays most outdoor rugged monitors/tablets use sunlight readable display technology, which relies on variations between the lumination (brightness) and also the illumination (ambient lightweight shining on a display). Lumination is that the quantity of sunshine energy emanating from the display (expressed in Cd/m²).
The readability depends on the quantity of sunshine being mirrored off the display. The best thanks to enhancing visibility is to extend brightness. A typical screen emits 350 Nits(Cd/m²). Some supply on the market feature 8,000 Nits. The result’s smart, however as a result of the supplementary lamps, high bright LCDs have disadvantages as well as high power consumption, excessive heat generation, exaggerated dimensions, electric circuit dependability issues, and shortened LCD period of time.
A second choice may be a transflective technology. Some TFT LCDs area unit is given a reflective mode of illumination while not compromising transmissive illumination. With obligatory reflective operate, changed digital displays replicate close lightweight passing the LCD cell and use mirrored lightweight beams as illumination. The stronger the close lightweight, the brighter the digital display seems. The changed digital display is visible below all lighting conditions as well as direct daylight despite the LCD’s original brightness. However, a daily transmissive digital display is troublesome to browse below sturdy close lightweight while not direct daylight. Issues detected in transflective LCDs embody a slender viewing angle, discoloration, low brightness, and loss of distinction.
How does a sunlight readable LCD work?
The sunlight viewable monitor and also the transflective LCD area unit solutions typically used for outside applications. However, each solution doesn’t seem to be extremely suited to industrial use. it’s necessary to require another route in attempting to regulate mirrored lights. As lightweight transfers from one material to a different, like air to glass, variations within the index of refraction can cause reflection. On the associate digital display screen, the additive reflection of the various surfaces is almost 15 % of close lightweight. If the full reflection is near the display’s brightness, the distinction of the display is reduced to the purpose wherever the display’s readability is diminished to unacceptable levels.
Options in bond technology for sunlight readable LCD monitors
Bond technology may be a third choice. It allows coupling of the front glass and also the internal glass, however, the price is high compared to what it brings in terms of quality. Options embody a typical show, associate improvement film applied on the interior screen rising brightness and distinction, and a polarizing film applied on each side of the touch screen to scale back lightweight reflection. The look includes a spot of 1.5 mm, between the 2 screens.This distance has the result of reducing Newton rings or the circular rainbow result which can be caused by non-uniform cell thickness yet as alternative defects leading to a flat surface involved with a rather hook like one.
faytech offers a sunlight readable LCD module that can be utilized in nearly any high brightness visibility area
Brightness is best to a typical screen (1000 Nits rather than 350 Nits for a typical Acura physical science screen). The touch screen options anti-glare and reflection surface treatments. Anti-reflective coated protection glass minimizes likeness and maximizes coefficient. Anti-glare coated protection glass scatters lightweight directed on the surface and softens the image of direct lightweight sources visible within the reflection of the viewing space.Typical product of Sunlight Readable rugged monitor could reach to 1600 Nits while for rugged tablet could be 1000 Nits. At least double brightness than traditional display. LED backlight technology can reduce the heat of screen and it extend the time of usage of the display even in extreme temperature environment. For example, some high end rugged display monitor could be used within -40C to 70C,almost double the temperature range than traditional product.
