Phoenix Display International (PDI), Tempe, AZ, has introduced a line of sunlight-readable 5.7-inch TFTs with QVGA (320 x 240) resolution. The modules have improved contrast, color saturation, and response time over CSTN products. PDI offers the 5.7" QVGA as a standard transmissive module with or without a touchscreen.
PDI achieves sunlight-readable performance by manufacturing the TFT cell using high aperture panel technology, high transmittance color filters, and a unique anti-reflective polarizer scheme. The extremely bright display is ideal for high ambient light or outdoor, high brightness applications.
The sunlight-readable model of the 5.7" QVGA TFT is illuminated with high intensity white LEDs and offers brightness of 300 cd/m2. The unit features a contrast ratio of 400:1 and a response time of 15 ms. The module utilizes HX8218A (Source) and HX8615A (Gate) drivers from Himax.
