HX8347 - Adafruit

HX8347-G(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver5.14.1 Module architecturesDATA SHEET Preliminary V01The HX8347-G can support two module architectures for CABC operation. The BL bitsetting of R3Dh can be used to select used display module architecture. White LEDdriver circuit for display backlight is located on the main PWB, not in the displaymodule both in architecture I and II.• Architecture ICABC_PWM_OUT1. BL =`1` of R3Dh2. LED backlight brightness for thedisplay is controlled by externaloutput “CABC_PWM_OUT”.• Architecture II1. BL =`0` of R3Dh2. LED backlight brightness data forthe display is read with DBV[7:0] bitsof R3Ch.3. Read commands R3Ch should besynchronized with V-sync.Himax ConfidentialFor Go-tek OnlyThis information contained herein is the exclusive property of Himax and shall not be distributed, reproduced, or disclosedin whole or in part without prior written permission of Himax.-P.114-October, 2009
