With the 4.3 inch LCD product line, Sharp is launching three small-format TFT displays, which offer real 16:9 widescreen viewing. The contrast ratio of 400:1, 16.7 million colours and 480 x RGB x 272 pixels provide outstanding picture quality. The displays integrate ASV technology, which extends the viewing angle to 160 degrees and thus ensures a clear picture even if the viewing angle is changed from frontal view. In addition, the panels and the LED background lighting only have a low thermal power loss – an important factor for mobile use. This makes the TFTs particularly suitable for modern handhelds with audio-visual features such as games consoles, portable media and DVD players. As a result of their multimedia qualities these units demand high standards in terms of the display picture quality. As well as purely consumer applications the modules could also be used in industry and medicine. Here it is essential to be able to show important images in full such as oscillator or ECG curves in the widest possible picture format.
For excellent clarity and perfect functioning even in difficult operating environments, the LQ043T3DX04 module also offers an extended temperature range from -20 to +60 Celsius and a luminance of up to 230 cd/m². A further model featuring a touch screen is also planned. The 4.3 inch LCDs can be controlled by an ARM based processor of the BlueStreak series, e.g. the ARM9-based 32-bit MCU LH7A404 with 266 MHZ, which is particularly suitable for multimedia applications.Samples of the LQ043T3DX04 module will be available from September. Series production is scheduled to start in Q4 2006. The LQ043T3DX02 is already in mass production.
