HX8347-G(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip DriverGamma resister streamDATA SHEET Preliminary V01The block consists of two gamma resister streams one is for positive polarity and theother is for negative polarity, each one including eight gamma reference voltages.VgP/N (0, 1, 2, 3, 8 20, 32(31), 43, 55, 60, 61, 62, 63). Furthermore, the block has apin (VGS) to connect a variable resistor outside the chip for the variation betweenpanels, if needed.Figure 5.33: Gamma resister stream and gamma reference voltageHimax 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.86-October, 2009

HX8347-G(T)240RGB x 320 dot, 262K color, TFT Mobile Single Chip DriverVariable resisterDATA SHEET Preliminary V01There are two types of variable resistors, one is for center adjustment and the other isfor offset adjustment. The resistances are decided by setting values in the centeradjustment, offset adjustment registers.
