Claim:
A projection TV comprising: an optical engine; a reflector; a screen: a gate line side driver connected to at least a first gate line and a second gate line; first 2m pixels connected to said first gate line; second 2m pixels connected to said second gate line; a first source line side driver connected to first to m-th source lines; a second source line side driver connected to (m+1)-th to 2m-th source lines; a first line memory comprising a first memory and a second memory; and a second line memory comprising a third memory and a fourth memory, wherein said first line memory is in a writing mode to store transmitted first to 2m-th signals for said first 2m pixels when said second line memory is in a reading mode to transmit stored first to 2m-th signals for said second 2m pixels, wherein said second memory stores said transmitted (m+1)-th to 2m-th signals after said first memory stores said transmitted first to m-th signals in said writing mode, wherein said third memory transmits said stored first signal and said fourth memory transmits said stored (m+1)-th signal simultaneously, and said third memory and said fourth memory sequentially transmit said stored first to m-th signals and said stored (m+1)-th to 2m-th signals, respectively, simultaneously.
