Embodiment
Fig. 1 is the panel driving system of one embodiment of the invention.Please refer to Fig. 1, in the present embodiment, panel driving system 100 comprises that a pixel panel 120 and drives chip 110.At this, pixel panel 120 is for example a panel with low temperature polycrystalline silicon technique made (LTPS panel).
In the present embodiment, drive chip 110 to comprise a driving chip controller 112, a panel driver element 114, one source pole driver element 116 and a power-supply unit 118.At this, drive chip controller 112 to comprise a time-after-time programmable memory 113 (multi-time programmable, MTP).
Specifically, drive chip controller 112 can according to burning in a burning code able to programme of MTP 113 provide respectively multiple control signals to panel driving unit 114, source drive unit 116 and power-supply unit 118 so that above-mentioned driver element can drive pixel panel 120 according to corresponding control signal.For example, driving under the control of chip controller 112, multiple horizontal clock signals can be exported in panel driving unit 114, to drive pixel panel 120, source drive unit 116 provides multiple data signals to pixel panel 120, with by corresponding pixel on these data signals writing pixel panels 120.In addition, power-supply unit 118 required power supply when providing pixel panel 120 to operate.
It should be noted that in the present embodiment, burning is corresponding to a specific customer information in the burning code able to programme of MTP 113.That is to say, by driving the control of chip controller 112, the driving signal that panel driving unit 114, source drive unit 116 and power-supply unit 118 provide can be subject to the impact of burning code able to programme, and drives pixel panel 120.At this, driving signal is for example horizontal clock signal, data signals and power signal.
In other words, the burning code able to programme that the driving chip 110 of the present embodiment can be different according to different customer information burnings, to drive the pixel panel 120 of different size, and then meets different clients' demand.Therefore, in the present embodiment, utilize programmable control to change the driving behavior of panel driving unit 114 and source drive unit 116, and then in the time of the specification variation of pixel panel 120, by disposable design, can the contingent all combinations of complete seating surface type structure.
To illustrate multiple exemplary embodiment below, so that the operation of panel driving system 100 to be described.
Fig. 2 is the pixel panel 120 of Fig. 1 and the enforcement schematic diagram of source drive unit 116.For convenience of description, Fig. 2 only shows the part framework of pixel panel 120 and source drive unit 116.For example, Fig. 2 only shows part data line and the part pixel in pixel panel 120, and wherein one group of data channel of source drive unit 116.
Please refer to Fig. 1 and Fig. 2, in the present embodiment, pixel panel 120 comprises multiple data lines 122 and multiple pixel P1～P18, and wherein each data line 122 comprises a switch 124.At this, the conducting state of each switch 124 is controlled by horizontal clock signal CKH1～CKH9 that panel driving unit 114 provides, and "+" of pixel number represents that this pixel is positive polarity in Fig. 2, and "-" of pixel number represents that this pixel is negative polarity.For example, in the time that horizontal clock signal CKH9 is high level, switch 124 corresponding to the color B2 of colored filter (color filter) 126 will be switched on, and then can be written into respectively pixel P6, the P15 of corresponding color B2 from data signals S1, the S2 of source drive unit 116.
It should be noted, different pixel panel 120, its switch 124 is not identical with the coupling mode of colored filter 126.In the present embodiment, be taking 124 as one groups, 9 switches, sequentially couple colored filter 126 color R1, G1, B1 ..., R3, G3, B3, the data line coupling with these switches receives the data signals S1 of source electrode driver element 116, as shown in Figure 2.Similarly, the data line coupling with other 9 switches receives the data signals S2 of source electrode driver element 116.But the present invention is not as limit.
On the other hand, in the present embodiment, Fig. 2 only shows wherein one group of data channel of source drive unit 116, and it selects signal NCH and data selection signal SWO1～SWO9, SWE1～SWE9 according to a polarity, provides data signals S1, S2 to corresponding data line 122.At this, one group of data channel comprises a positive polarity data channel and a negative polarity data channel.
Specifically, taking positive polarity data channel as example, multiplexer MUX5 one 9 selects 1 multiplexer, and it selects corresponding data signals output according to data selection signal SWO1～SWO9.For example, in the time receiving data selection signal SWO5, multiplexer MUX5 can select to export the data signals of corresponding color G2.Then, be high level if polarity is selected signal NCH, multiplexer MUX3 can receive the data signals of exporting from multiplexer MUX5.Afterwards, this data signals can sequentially be processed via level shifter LVS (+), digital analog converter DAC (+) and the output buffer OP (+) of positive polarity data channel, and becomes the data signals with positive polarity.Then, select signal NCH according to the polarity of high level, multiplexer MUX1 can receive this and have the data signals of positive polarity, and is exported to data line 122 corresponding in pixel panel 120.
That is to say, in this example, select signal NCH and horizontal clock signal CKH9 by data selection signal SWO5, polarity, panel driving unit 114 and source drive unit 116 can drive pixel panel 120, with T1 during driving by corresponding color G2 and there is the data signals S1 writing pixel P5 of positive polarity.
In this simultaneously, select signal NCH and horizontal clock signal CKH9 by data selection signal SWE5, polarity, panel driving unit 114 and source drive unit 116 can drive pixel panel 120, by negative polarity data channel during driving T1 by corresponding color G2 and there is the data signals S2 writing pixel P14 of negative polarity.
Then, T2 during driving, in the time that polarity selects signal NCH to switch to low level, multiplexer MUX4 can receive the data signals of exporting from multiplexer MUX5, and multiplexer MUX1 can receive level shifter LVS (-), digital analog converter DAC (-) and the rear data signals of exporting of output buffer OP (-) processing of negative polarity data channel.Therefore, T2 during driving, multiplexer MUX1 can and have the data signals S1 writing pixel P5 of negative polarity by corresponding color G2.
On the contrary, T2 during driving, in the time that polarity selects signal NCH to switch to low level, multiplexer MUX3 can receive the data signals of exporting from multiplexer MUX6, and multiplexer MUX2 can receive level shifter LVS (+), digital analog converter DAC (+) and the rear data signals of exporting of output buffer OP (+) processing of positive polarity data channel.Therefore, T2 during driving, multiplexer MUX2 can and have the data signals S2 writing pixel P14 of positive polarity by corresponding color G2.
In the present embodiment, the data signals that multiplexer MUX3, MUX4 select the level of signal NCH to decide reception multiplexer MUX5 or MUX6 to export according to polarity, and the data signals that multiplexer MUX1, MUX2 also select the level of signal NCH to decide reception output buffer OP (+) or OP (-) to export according to polarity.
It should be noted, in order to ensure the correctness of the data signals of writing pixel, in the time that multiplexer MUX3 receives the data signals that multiplexer MUX5 exports, multiplexer MUX1 must receive the data signals that output buffer OP (+) exports.In the time that multiplexer MUX4 receives the data signals that multiplexer MUX6 exports, multiplexer MUX2 must receive the data signals that output buffer OP (-) exports.Similarly, in the time that multiplexer MUX4 receives the data signals that multiplexer MUX5 exports, multiplexer MUX1 must receive the data signals that output buffer OP (-) exports.In the time that multiplexer MUX3 receives the data signals that multiplexer MUX6 exports, multiplexer MUX2 must receive the data signals that output buffer OP (+) exports.
In the present embodiment, to open corresponding switch 124 as example taking horizontal clock signal CKH9, T1, T2 during driving, when other horizontal clock signal CKH1～CKH8 opens corresponding switch 124, when can respectively data signals S1, S2 being write to corresponding pixel by aforesaid operations mode, just repeat no more at this.
In the present embodiment, taking a line in pixel panel 120 (line) pixel as example, from the polarity of this row pixel P1～P18 T1, T2 during different drivings, the source drive unit 116 of the present embodiment is to drive pixel panel 120 in a mode for reversion (dot inversion), so that pixel panel 120 shows the image frame of corresponding data signal.
In addition, due to multiplexer MUX3, data signals that MUX4 provides, its voltage level is lower, therefore under the type of drive of a reversion, the level shifter LVS (+) of positive polarity data channel can draw high the voltage level of multiplexer data signals that MUX3 provides, and the level shifter LVS (-) of negative polarity data channel can reduce the voltage level of multiplexer data signals that MUX4 provides.
For example, if multiplexer data signals that MUX3 provides, its voltage level is 1.8V, and level shifter LVS (+) can be drawn high as 6.5V; And if multiplexer data signals that MUX3 provides, its voltage level is 0V, level shifter LVS (+) can't draw high its voltage level, and makes it maintain 0V.
On the other hand, if multiplexer data signals that MUX4 provides, its voltage level is 1.8V, and level shifter LVS (-) can be reduced to 0V; And if multiplexer data signals that MUX3 provides, its voltage level is 0V, level shifter LVS (-) can be reduced to-6.5V.
In the present embodiment, horizontal clock signal CKH1～CKH9 sequentially opens corresponding switch 124, and then data signals S1, S2 is write to corresponding pixel according to one first conducting order CKH9, CKH8, CKH7, CKH6, CKH5, CKH4, CKH3, CKH2, CKH1.
For compensation panel, the time of opening with average priority, in the present embodiment, horizontal clock signal CKH1～CKH9 also can be set as sequentially opening corresponding switch 124, and then data signals S1, S2 being write to corresponding pixel according to one second conducting order CKH1, CKH2, CKH3, CKH4, CKH5, CKH6, CKH7, CKH8, CKH9.
