PANEL DRIVING DEVICE AND DISPLAY DEVICE HAVING THE SAME |
摘要 |
A panel driving device for driving a display panel including N data lines is disclosed. The panel driving device includes a memory array and a source driver. The memory array includes M memory blocks, a controller and an output unit. Each memory block includes N memory units. The controller is configured to divide serial image data into M groups of sub-image data and write each group of sub-image data into the corresponding memory block sequentially, wherein each group of sub-image data has N sub-image data. The output unit is configured to output the data in the M memory blocks sequentially in a time division manner in response to a selection signal. The source driver includes N driving units having the same configuration. After the driving unit receives the time-divided data output from the output unit, signal processing is performed to generate an image signal to be output to the corresponding data line. |
