发明名称 Display panel driving device and driving method thereof for saving electrical energy
摘要 A display panel driving device and a driving method thereof are provided. The display panel driving device includes a host and a driving chip, in which the driving chip includes a store unit and a driving module. The host switches sources of image data received by the driving module according to content of the image data, so as to determine whether the driving module receives the image data from the store unit or not.

主权项 1. A display panel driving device, comprising: a host, for providing image data; and a driving chip, for driving a display panel to display frames according to the image data, the driving chip comprising: a store unit, for storing the image data; a driving module, coupled to the store unit, for driving the display panel to display the frames according to the image data, wherein the host switches sources of the image data received by the driving module according to the content of the image data, so as to determine whether the driving module receives the image data from the store unit or not; and a transmitting interface unit, coupled to the host, the store unit and the driving module, wherein the host controls the transmitting interface unit to transmit the image data to at least one of the store unit and the driving module according to the content of the image data, wherein when the content of the image data is dynamic frames, the host disenables all the store unit for storing the image data from transmitting the image data during a period for displaying dynamic frames, and controls the transmitting interface unit to transfer the image data to the driving module, and wherein when the content of the image data converts from dynamic frames to static frames, the host enables the store unit in a period of the last dynamic frame, and controls the transmitting interface unit to transmit the image data to the store unit and the driving module at the same time in a period of a first frame after the content converts to the static frames.
