HX8346-A(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip Driver5.1.2 RGB InterfaceDATA SHEET V01The HX8346-A supports the RGB interface for animated display data written. TheRGB interface can be selected by setting internal RGB_EN bit = 1. In RGB interfacethe display operations is executed in synchronization with the frame synchronizingsignal (VSYNC), line synchronizing signal (HSYNC) and dot clock (DOTCLK), and thedisplay data is input via RGB interface circuit without being written to the GRAM anddisplay directly. The display data are transferred in pixel unit via D23-0 input pins. Thedisplay data input is latched in the rising edge of DOTCLK (DPL bit = 0) or in thefalling edge of DOTCLK (DPL bit = 1) by the chip when ENABLE signal is validdescribed in Table 5.7EPL ENABLE Display0 0 Disable0 1 Enable1 0 Enable1 1 DisableTable 5. 7 EPL bit Setting and Valid ENABLE Signal(VSPL bit=0)VSYNCVertical Back porchDisplay areaDisplaperio ydHorizontalBackporchHSYNCDOTCLKENABLE( HSPL bit = 0 )( DPL bit = 0 )( EPL bit = 0 )D17-0Figure 5. 19 RGB Interface Circuit Input TimingHimax ConfidentialThis 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.48-July, 2007
