B. LTP-2844A3 The LTP-2844A3 are multicolor applicable displays. The multicolor displays have gray face and white dots. The LTP-2344 series are single color displays. The yellow,green and red orange displays have gray face and white dot color. The AlGaAs red devices have red face and red dots. The green series devices utilize LED chipse which are made from GaP on a transparent GaP substrate. The yellow and red orange series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate. The AlGaAs red series devices utilize LED chips which are made from AIGaAs on a non-transparent GaAs substrate. Notes : All dimensions are in millimeters(inches).
