Secondary to each pixel electrode applying bias voltage.
The flow chart of the image element driving method that Fig. 1 provides for the embodiment of the present invention, as it can be seen, the step of image element driving method
Rapid as follows:
1, sequential control circuit is with the first operating frequency output timing control signal.
Initial frame sequential control circuit presses the first operating frequency to data drive circuit and scan drive circuit transmission timing
Control signal.Further, after scan drive circuit receives timing control signal, output high level signal makes thin film transistor (TFT)
Grid voltage more than threshold voltage, the source electrode of thin film transistor (TFT) connects with drain electrode, the operating frequency decision of timing control signal
The speed that on column direction, thin film transistor (TFT) is sequentially communicated.The operating frequency of timing control signal is the highest, and the thin film of every a line is brilliant
The switching rate of body pipe on off operating mode is the fastest.Data drive circuit receives output voltage signal after timing control signal, same
Moment only has the pixel electrode being connected with thin film transistor (TFT) and receives voltage signal generation bias voltage.Due to single pixel electrode
Display state area be divided on state of and dark-state, the pixel electrode that the pixel electrode that on state of shows and dark-state show is staggered, number
Switching frequency according to drive circuit correspondence scan drive circuit switches the voltage signal of output, the operating frequency of timing control signal
The highest, the voltage signal switching rate of data control circuit output is the fastest.After each pixel electrode is applied in bias voltage,
Display floater completes the output of a frame picture, and in the unit interval, frame number is the most, and the fluency of picture is the highest.
Sequential control circuit with the first operating frequency output timing control signal, meets display picture smooth at initial frame
The requirement of degree.
2, detecting unit detecting liquid crystal display is in the display pattern of present frame.
In the present embodiment, the primary colours data signal that detecting unit is sent to sequential control circuit according to system board judges to work as
The display pattern of front frame.Primary colours data signal controls the content of display floater output image, and heavy duty picture display mode is heavy with non-
The picture material carrying picture display mode is different, therefore system board sends different primary colours data letters to described sequential control circuit
Number, detecting unit i.e. can determine whether the display pattern of present frame by detecting primary colours data signal.
The method that detecting unit judges present frame display pattern by detection primary colours data signal, display mode decision is accurate
Really, the follow-up control to timing control signal operating frequency.
3, processing unit transmission frequency signal is to sequential control circuit.

The frequency of storage control signal is the biggest, and the high level of data drive circuit output is the fastest with low level switching rate；Sequencing contro
Circuit transmission frame initial pulse signal is to scan drive circuit, and frame initial pulse signal is the initial signal of each frame picture, defeated
Going out a frame initial pulse signal and mean the beginning of a frame picture, the frequency of frame initial pulse signal is the biggest, in the same time
Picture frame number the most；Sequential control circuit sends line scanning clock signal to scan drive circuit, line scanning clock signal control
Making the gate switch state of single thin film transistor (TFT), the frequency of line scanning clock signal is the biggest, the switch shape of each thin film transistor (TFT)
State switching rate is the fastest.
Further, data latches control signal, frame initial pulse signal and line scanning clock signal synchronism output, sweep
Retouch while drive circuit is sequentially communicated every a line thin film transistor (TFT), data drive circuit switch successively high level with low level
Output.
Under non-heavy duty image mode, sequential control circuit keeps exporting each timing control signal with the first operating frequency, full
The foot requirement to display picture fluency；Under heavy duty image mode, sequential control circuit is with relatively low the second operating frequency of frequency

Problem, keeps the job stability of liquid crystal display, prevents liquid crystal display from damaging.
5, data drive circuit and scan drive circuit drive the work of each pixel electrode.
The picture that liquid crystal display shows enters next frame, and scan drive circuit receives frame initial pulse signal and row is swept
After retouching clock signal, control each thin film transistor (TFT) and in turn switch on along matrix column direction；Data drive circuit receives data lock
After storage control signal, the connection order of corresponding thin film transistor (TFT), along column direction, pixel electrode is applied bias voltage.Sequential control
Data latches control signal, frame initial pulse signal and the line scanning clock signal frequency that circuit processed is sent by the second operating frequency
Rate is less relative to the first operating frequency, voltage signal switching rate between high level and low level of data drive circuit output
Relatively low, the caloric value of data drive circuit is less.Under heavy duty image mode, operational amplifier makes number owing to workload strengthens
Increasing according to drive circuit caloric value, timing control signal exports according to the second operating frequency that frequency is relatively low, data drive circuit
The heat that switching voltage signal produces reduces, and the total amount of heat that data drive circuit work produces obtains relative minimizing, equipment work
Make stability to promote.
In the present embodiment, in each frame display picture, detecting unit all detects the display pattern of present frame, and according to detecting
The operating frequency of the timing control signal of output control next frame.For example, it is assumed that present frame is nth frame, detecting unit detects N
The display pattern of frame, according to the operating frequency of the timing control signal of detecting output control N+1 frame；Display picture enters N+
1 frame, i.e. present frame are N+1 frame, and detecting unit detects the display pattern of N+1 frame, according to detecting output control N+2 frame
The operating frequency of timing control signal, circulates with this and carries out.
The work of the display model selection timing control signal of the present frame that sequential control circuit detects according to detecting unit
Working frequency, non-heavy duty image mode uses the first operating frequency that frequency is higher, meets the requirement to display picture fluency；Weight
Carry the second operating frequency that image mode use frequency is relatively low, alleviate the load of data drive circuit, alleviate data drive circuit
The problem that heating, device temperature raise, keeps the job stability of liquid crystal display, prevents liquid crystal display from damaging.
