HX8347-G(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver5.4 Tearing effect output lineDATA SHEET Preliminary V01The Tearing Effect output line supplies to the MPU a Panel synchronization signal.This signal can be enabled or disabled by the Tearing Effect Line Off & On commands.The mode of the Tearing Effect signal is defined by the parameter of the TearingEffect Line On command. The signal can be used by the MPU to synchronize FrameMemory Writing when displaying video images.Tearing effect function is not supported for RGB interface (RCM[1:0]=”1x”).5.4.1 Tearing effect line modesMode 1, The Tearing Effect Output signal consists of V-Blanking Information only:t Vdh= The LCD display is not updated from the Frame Memoryt vdl = The LCD display is updated from the Frame Memory (except Invisible Line – see below)Figure 5.17: TE mode 1 outputUnder Mode1, the TE output timing will be defined by TSEL[15:0] setting.Ex:1. TSEL[15:0]=0, then TE signal will output after last Line finished.2. TSEL[15:0]=2, then TE signal will output at second Line start.Figure 5.18: TE delay outputHimax 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.73-October, 2009
