Apply technique scheme of the present invention; the liquid crystal display overdrive circuit of the present invention's protection comprises LUT circuit 300 and ADC400; the previous frame data adjacent with current frame data are stored by utilizing ADC400; the current frame data of Latch200 transmission is received by LUT circuit 300; foundation current frame data and the previous frame data decimation one OD motivation value read from ADC400; described OD motivation value is sent to DAC500, drives display panels output display current frame data to make DAC500 according to described OD motivation value.Therefore liquid crystal display overdrive circuit provided by the invention utilizes cost to replace RAM lower than the simple and easy ADC of RAM, without the need at the higher RAM of setup cost, reduces system complexity, has saved circuit cost.
In order to technical scheme of the present invention is described in further detail; equipment TCON600, SD100 that the specific field that the liquid crystal display overdrive circuit protected the present invention relates to comprises by the present inventor, and each structure in liquid crystal display overdrive circuit elaborates further.
First for TCON600 and SD100 in the present invention, TCON600 is used for the vision signal that real-time reception signal source sends, and described vision signal is converted to for driving the first control signal of GD (Gate Driver, gate driver), for driving second control signal of SD100 and the described current frame data for display.
In the present invention, vision signal comprises RGB (RGB) color mode data, clock signal, horizontal-drive signal and vertical synchronizing signal.When TCON600 at least receives this four kinds of data-signals, these four kinds of data-signals are processed, changed, generate two control signals and a data-signal.
Wherein, two control signals are respectively for driving the first control signal of the in good time door capable of being opened of GD (Gate) and for driving SD100 when door is opened, writing the second control signal of the pixel voltage value of the described current frame data for display at described display panels in certain one-row pixels of front opening.A data-signal is the current frame data of wish display.
In actual application, suppose that current frame data arranges a pixel by the capable * N of M and forms, M, N are positive integer, frame data of middle finger of the present invention, and the capable * N of the M that these frame data namely referred to comprise arranges the pixel voltage value of a pixel.When GD control gate is opened at every turn, all only control certain one-row pixels correspondence and open.So in the present invention, when the first control signal is sent to GD by TCON600, after GD opens according to this first control signal control gate in good time, also just certain current for display panels one-row pixels is opened.
Specifically in the present invention, the second control signal and the described current frame data for display all can be sent to SD100 by TCON600.Wherein, the Latch200 be arranged in SD100 can receive and store the current frame data of the wish display that described TCON600 sends, and SD100 can according to the execution of the second control signal toggle-write operations.Specifically can consult shown in Fig. 3.
After GD opens according to the first control signal control gate in good time, SD100 reads the current frame data stored in Latch200, writes the pixel voltage value of described current frame data at described display panels in certain one-row pixels of front opening.
By that analogy, the every control gate of GD is opened once, SD100 just reads the current frame data once stored from Latch200, in the current line pixel of front opening, the pixel voltage value of described current frame data is write at described display panels, until the pixel voltage value of all pixels all completes write in described display panels, now represent that frame data complete write.
Certainly, in the present invention after a certain frame data complete write, GD when control gate opens one time again, namely opens the process of write next frame data.
Secondly for the Latch200 in the present invention, Latch200 for receiving and storing the current frame data for display that described TCON600 sends, and send described current frame data to described LUT circuit 300.
In the present invention, after the current frame data for display is sent to SD100 by TCON600, the Latch200 be arranged in SD100 receives and stores described current frame data, and gives LUT circuit 300 with certain frequency by described current frame data forwarding.
