Clean and Clear image   Texas Instruments USA’s state of the art DLP technology enables DPS-1 to produce clean and clear photos.     The spaces of between DMD chips are much narrow than that of LCD. That’s why image of DLP technology has no screen door effect. And LCD method transmits light through the its panel and can help but loss light.   Slower decreasing rates of Contrast DLP technology has much slower decreasing rates of contrast than LCD.           Long life span It is very durable. Its life span is up to 40 years when you run this system 8 hours a day.       DLP technology (Texas Instruments Incorporated is the world leader in digital signal processing and analog technologies, the semiconductor engines of the Internet age.)
