TFT LCD survives rough use

Heat conductors transport the dissipation heat of the LEDs to the rear outer side of the panel where it can be easily given off into the environment.

Sharp's LQ104V1DG62 10.4in display is an industry-compatible TFT LCD with an LED backlight.

Like all displays in the Strong2 series from Sharp, the new industry display from Sharp is also characterised by extreme resilience.

The special housing design means that the new industry TFT LCD withstands accelerations of up to 14.7m/s2 in the range of 57 - 500kHz during the vibration test.

In a standard impact test, the display can withstand impacts with acceleration values of up to 490m/s2 without damage when switched off.

Sharp has designed the housing specifically for the LED backlight and equipped it with dedicated heat management.

Heat conductors transport the dissipation heat of the LEDs to the rear outer side of the panel where it can be easily given off into the environment.

Like all the other displays in the series, the new LED backlight variant of the proven Strong2 LCDs offers an operating temperature of -30 to +80C and a lifecycle of 50,000 hours.

With conventional LCDs with LED backlight, it is frequently only the CCFL cartridge that is replaced with an insert fitted with LEDs that is unable to give off the heat into the environment easily.

Compared to the CCFL variant, conventional LCDs with LED backlights are therefore mostly designed for an operating temperature limited to the upper range and have a shortened lifecycle.

The LQ104V1DG62, however, combines the high resilience required of industrial applications with the benefits of an LED backlight.

These advantages include the prompt response characteristics of the LEDs, even at very low temperatures.

It also offers excellent dimmability over the entire brightness range of the LEDs.

The new TFT LCD is particularly suitable where tough application conditions meet rapidly changing light conditions, for example in outdoor areas for forest, farming and construction machinery, as well as transport applications.

The low operating voltage of the display means that the high-voltage convertor required for CCFL lamps is no longer necessary.

This reduces system complexity and allows the display's use in areas where there is a risk of explosion.

These applications usually include production sites where large quantities of dust occur (such as flour-processing) or where easily inflammable liquids are handled, for example in the petrochemicals industry.
