A brightness of 800 cd/m² is provided by strong LED backlight. As a result, the display can be read even at very bright ambient light. In addition, the dimming capability of the LEDs has the advantage that the display brightness can be adapted to changing light conditions. A feature of particular importance for high brightness displays, because the maximum brightness is normally only required for a short time at corresponding ambient light levels. With cloudy skies and certainly when it is dark displays are often too bright and can provoke glare or interfering reflections; the ability to dim displays according to light conditions is therefore necessary for many applications. This is normally done by pulse width modulation, which is controlled by ambient light sensors, such as types GA1Axxxx Sharp provides in its optoelectronic component portfolio. Furthermore, adaptive backlight control also reduces average power consumption of the overall system.
The image reproduction of the LQ121S1DC71 is based on the SVGA resolution with 800 x 600 pixels and 260,000 colours, the high static contrast of 800:1 and the large viewing angle of 160° h/v.
Overall, the 12.1 TFT LCD has been designed to combine high brightness with high durability as well as good image quality. The LQ121S1DC71 is well suited to applications, which are used outside most or some of the time and are subject to considerable operational demand. Consequently, target applications are typically ATMs and vending machines as well as e-kiosks and information terminals, but also agriculture and forestry machines, testing and measurement devices as well as screens for boats and ships
