发明名称 DISPLAY DRIVE CIRCUIT AND METHOD
摘要 PROBLEM TO BE SOLVED: To provide a display drive circuit and method that can achieve division output of an image data signal at low manufacturing cost. SOLUTION: The display drive circuit which divides the image data signal DI by respective horizontal periods to generate and output a plurality of divided image data signals Dout0 and Dout1 includes a line memory 14 where the image data signal DI is written by pixels and the written signal DI is read out and which has total storage capacity of at least one horizontal period of the image data signal, and a control circuit 16 which controls the line memory 14 to alternately write and read out the image data signal DI, and controls the line memory 14 so that when the image data DI is divided into the divided image data signals Dout0 and Dout1, the image data signal DI begins to be read out by horizontal periods after divided image data signals output as first signals by the horizontal periods are both written.
