STEREOSCOPIC IMAGE DISPLAY

摘要

PURPOSE: A three-dimensional image display device is provided to generate 3D driving voltage by increasing gamma compensation voltage or dividing high potential power voltage and gate high voltage. CONSTITUTION: A programmable gamma IC(PGMA)(90) comprises a control interface(91) and a DAC(Digital Analog Converter)(92). A serial clock(SCL) and serial data(SDA) are inputted to the programmable gamma IC. Gamma data which is stored in a nonvolatile memory is updated. A gamma compensation voltage(OUT1-OUT6) and a common voltage(Vcom) are controlled. Control interface inputs inputted serial data to the nonvolatile memory. DAC converts the digital data received from a register into the analog voltage and generates the gamma compensation voltages and the common voltage. A 3D driving voltage generating circuit(106) is embedded in the programmable gamma IC.
