Description

Driving chip, panel driving system and panel driving method

technical field

The present invention relates to a panel driving system and its method, in particular to a low-temperature polysilicon panel driving system and its method.

Background technique

Low-temperature polysilicon (LTPS) is the manufacturing process of a new generation of thin-film transistor liquid crystal displays. The biggest difference from the traditional amorphous silicon display is that the display panel made of LTPS has a faster response speed, high brightness and high resolution.

Therefore, in the application of active-matrix liquid crystal display (AMLCD) and active-matrix organic light emitting diode (Active-matrix organic light emitting diode, AMOLED) integrated circuits, LTPS panels have also attracted a lot of attention. . In the liquid crystal display of the LTPS panel, the pixel circuit and the driving circuit are implemented on a single glass substrate with polysilicon thin film transistors to reduce system cost. In fact, many active matrix LCDs with LTPS panels have been implemented in portable systems such as mobile phones, digital cameras, and notebook computers.

However, traditional driver chips are designed according to the specifications provided by customers to design the control signals of the LTPS panel and the driving timing of the source driver. Therefore, corresponding to different LTPS panels, different driving methods usually need to be used. Driver chips designed according to the specifications provided by a specific customer will not be able to be used in other customers' LTPS panels. That is to say, if the driver chip is to support more than two kinds of LTPS panels, the two corresponding driving timings must be designed in the driver chip respectively. To support LTPS panels of other customers in the future, the driver chip must be redesigned, and must be designed according to the specifications of different customers, which will consume more hardware and design time.

Detailed ways

FIG. 1 is a panel driving system according to an embodiment of the present invention. Please refer to FIG. 1 , in this embodiment, a panel driving system 100 includes a pixel panel 120 and a driving chip 110 . Here, the pixel panel 120 is, for example, a panel (LTPS panel) manufactured by a low temperature polysilicon process.

In this embodiment, the driver chip 110 includes a driver chip controller 112 , a panel driver unit 114 , a source driver unit 116 and a power supply unit 118 . Here, the driver chip controller 112 includes a multi-time programmable memory 113 (multi-time programmable, MTP).

Specifically, the driver chip controller 112 can provide a plurality of control signals to the panel driver unit 114, the source driver unit 116, and the power supply unit 118 according to a programmable programming code burned in the MTP 113, so that the above-mentioned driving The units can drive the pixel panel 120 according to corresponding control signals. For example, under the control of the driver chip controller 112, the panel driver unit 114 outputs a plurality of horizontal clock signals to drive the pixel panel 120, and the source driver unit 116 provides a plurality of data signals to the pixel panel 120 to drive the pixel panel 120. These data signals are written into corresponding pixels on the pixel panel 120 . In addition, the power supply unit 118 is used to provide the power required for the operation of the pixel panel 120 .

It should be noted that, in this embodiment, the programmable programming code programmed into the MTP 113 corresponds to a specific customer information. That is to say, through the control of the driving chip controller 112 , the driving signals provided by the panel driving unit 114 , the source driving unit 116 and the power supply unit 118 are affected by the programmable programming code to drive the pixel panel 120 . Here, the driving signal is, for example, a horizontal clock signal, a data signal and a power signal.

In other words, the driver chip 110 of this embodiment can burn different programmable programming codes according to different customer information, so as to drive pixel panels 120 of different specifications, so as to meet the needs of different customers. Therefore, in this embodiment, programmable control is used to change the driving behavior of the panel driving unit 114 and the source driving unit 116, and then when the specification of the pixel panel 120 changes, the panel can be fully supported through a one-time design. All possible combinations of architectures.

Several exemplary embodiments will be illustrated below to illustrate the operation of the panel driving system 100 .

FIG. 2 is a schematic diagram of implementation of the pixel panel 120 and the source driving unit 116 in FIG. 1 . For convenience of illustration, FIG. 2 only shows partial structures of the pixel panel 120 and the source driving unit 116 . For example, FIG. 2 only shows part of the data lines and part of the pixels on the pixel panel 120 , and one set of data channels of the source driver unit 116 .

Please refer to FIG. 1 and FIG. 2 , in this embodiment, the pixel panel 120 includes a plurality of data lines 122 and a plurality of pixels P1 ˜ P18 , wherein each data line 122 includes a switch 124 . Here, the conduction state of each switch 124 is controlled by the horizontal clock signals CKH1-CKH9 provided by the panel driving unit 114, and the "+" sign of a pixel in FIG. -" means the pixel is negative polarity. For example, when the horizontal clock signal CKH9 is at a high level, the switch 124 corresponding to the color B2 of the color filter 126 will be turned on, and then the data signals S1 and S2 from the source driving unit 116 can be The pixels P6 and P15 corresponding to the color B2 are respectively written.

It should be noted that, different pixel panels 120 have different coupling methods between the switches 124 and the color filters 126 . In this embodiment, 9 switches 124 are used as a group to sequentially couple the colors R1, G1, B1, ..., R3, G3, B3 of the color filter 126, and these switches are coupled The data line receives the data signal S1 of the source driving unit 116 , as shown in FIG. 2 . Similarly, the data lines coupled to the other nine switches receive the data signal S2 of the source driving unit 116 . But the present invention is not limited thereto.

On the other hand, in this embodiment, FIG. 2 only shows one group of data channels of the source driver unit 116, which provides data according to a polarity selection signal NCH and data selection signals SWO1-SWO9, SWE1-SWE9. The signals S1 and S2 are sent to the corresponding data lines 122 . Here, a set of data channels includes a positive polarity data channel and a negative polarity data channel.

In detail, taking the positive polarity data channel as an example, the multiplexer MUX5 is a 9-to-1 multiplexer, which selects the corresponding data signal to output according to the data selection signals SWO1˜SWO9. For example, when receiving the data selection signal SWO5, the multiplexer MUX5 will select and output the data signal corresponding to the color G2. Then, if the polarity selection signal NCH is at high level, the multiplexer MUX3 will receive the data signal output from the multiplexer MUX5. After that, the data signal will be sequentially processed by the level shifter LVS(+), the digital-analog converter DAC(+) and the output buffer OP(+) of the positive polarity data channel to become a data signal with positive polarity. Then, according to the high-level polarity selection signal NCH, the multiplexer MUX1 receives the data signal with positive polarity and outputs it to the corresponding data line 122 on the pixel panel 120 .

That is to say, in this example, by using the data selection signal SWO5, the polarity selection signal NCH and the horizontal clock signal CKH9, the panel driving unit 114 and the source driving unit 116 can drive the pixel panel 120, so that the corresponding The data signal S1 with color G2 and positive polarity is written into the pixel P5.

At the same time, with the data selection signal SWE5, the polarity selection signal NCH and the horizontal clock signal CKH9, the panel driving unit 114 and the source driving unit 116 can drive the pixel panel 120, and the negative polarity data channel will correspond to the driving period T1 The data signal S2 with color G2 and negative polarity is written into the pixel P14.

Then, during the driving period T2, when the polarity selection signal NCH is switched to low level, the multiplexer MUX4 will receive the data signal output from the multiplexer MUX5, and the multiplexer MUX1 will receive the negative pole The output data signal is processed by the level shifter LVS(-), the digital-to-analog converter DAC(-) and the output buffer OP(-) of the sex data channel. Therefore, during the driving period T2, the multiplexer MUX1 writes the negative polarity data signal S1 corresponding to the color G2 into the pixel P5.

On the contrary, during the driving period T2, when the polarity selection signal NCH is switched to low level, the multiplexer MUX3 will receive the data signal output from the multiplexer MUX6, and the multiplexer MUX2 will receive The data signal output after processing by the level shifter LVS(+), the digital-to-analog converter DAC(+) and the output buffer OP(+) of the positive polarity data channel. Therefore, during the driving period T2, the multiplexer MUX2 writes the data signal S2 corresponding to the color G2 and having a positive polarity into the pixel P14.

In this embodiment, the multiplexers MUX3 and MUX4 decide to receive the data signal output by the multiplexer MUX5 or MUX6 according to the level of the polarity selection signal NCH, and the multiplexers MUX1 and MUX2 also The data signal output by the receiving output buffer OP(+) or OP(-) is determined according to the level of the polarity selection signal NCH.

It should be noted that in order to ensure the correctness of the data signal written into the pixel, when the multiplexer MUX3 receives the data signal output by the multiplexer MUX5, the multiplexer MUX1 must receive the output buffer The data signal output by OP(+). When the multiplexer MUX4 receives the data signal output from the multiplexer MUX6, the multiplexer MUX2 must receive the data signal output from the output buffer OP(−). Similarly, when the multiplexer MUX4 receives the data signal output from the multiplexer MUX5, the multiplexer MUX1 must receive the data signal output from the output buffer OP(−). When the multiplexer MUX3 receives the data signal output from the multiplexer MUX6, the multiplexer MUX2 must receive the data signal output from the output buffer OP(+).

In this embodiment, the horizontal clock signal CKH9 is used as an example to turn on the corresponding switch 124. During the driving period T1 and T2, when the other horizontal clock signals CKH1-CKH8 turn on the corresponding switch 124, the data signal can be respectively transmitted by the above operation method. S1 and S2 are written into corresponding pixels, which will not be repeated here.

In this embodiment, a line of pixels on the pixel panel 120 is taken as an example, and the polarities of the pixels P1 to P18 in this line during different driving periods T1 and T2 can be known. The source driving unit 116 of this embodiment The pixel panel 120 is driven in a dot inversion manner, so that the pixel panel 120 displays an image frame corresponding to the data signal.

In addition, since the voltage level of the data signals provided by the multiplexers MUX3 and MUX4 is relatively low, in the dot inversion driving mode, the level shifter LVS(+) of the positive polarity data channel will pull up more The voltage level of the data signal provided by the multiplexer MUX3, and the level shifter LVS(-) of the negative polarity data channel will reduce the voltage level of the data signal provided by the multiplexer MUX4.

For example, if the voltage level of the data signal provided by the multiplexer MUX3 is 1.8V, the level shifter LVS(+) will pull it up to 6.5V; The voltage level of the data signal is 0V, the level shifter LVS(+) will not pull up the voltage level, but keep it at 0V.

On the other hand, if the data signal provided by the multiplexer MUX4 has a voltage level of 1.8V, the level shifter LVS(-) will reduce it to 0V; and if the data signal provided by the multiplexer MUX3 The data signal, whose voltage level is 0V, will be reduced to -6.5V by the level shifter LVS(-).

In this embodiment, the horizontal clock signals CKH1˜CKH9 are, for example, according to a first conduction sequence CKH9, CKH8, CKH7, CKH6, CKH5, CKH4, CKH3, CKH2, CKH1 to sequentially turn on the corresponding switches 124, and then turn on the data signal S1 and S2 are written into corresponding pixels.

In order to compensate for the average turn-on time of the panel, in this embodiment, the horizontal clock signals CKH1-CKH9 can also be set to follow a second turn-on sequence CKH1, CKH2, CKH3, CKH4, CKH5, CKH6, CKH7, CKH8 , CKH9 turn on the corresponding switches 124 in sequence, and then write the data signals S1 and S2 into the corresponding pixels.

In this embodiment, the driver chip controller 112 may include two sets of registers (not shown) to store the settings of the first conduction sequence and the second conduction sequence of the switches 124 . It should be noted that the above-mentioned first conduction sequence and second conduction sequence are only exemplary embodiments, and the present invention is not limited thereto.

Therefore, even though different pixel panels have different coupling methods of switches and color filters, the driver chip 110 of this embodiment utilizes programmable horizontal clock signals CKH1-CKH9 and data selection signals SWO1-SWO9, SWE1 ~SWE9 can drive different pixel panels, which has met the needs of customers.

In this embodiment, the driver chip controller 112 has provided two sets of registers for storing the settings of the conduction sequence of the switches, but the driver chip controller 112 may also include another register (not shown) for storing A setting that determines when to switch the conduction sequence.

For example, in this embodiment, it can be set that the first conduction sequence is used to sequentially conduct the switches 124 in each frame and each row of pixels, so as to write the corresponding data signals S1, S2.

Alternatively, it can be set that each line of pixels uses the first conduction order to turn on the switches 124 sequentially in odd frames, and uses the above-mentioned second conduction sequence in even frames. The switches 124 are sequentially turned on to write the corresponding data signals S1 and S2.

Alternatively, it can be set that in the first odd frame, the switches 124 are turned on sequentially using the conduction sequence CKH1, CKH2, CKH3, CKH4, CKH5, CKH6, CKH7, CKH8, and CKH9; The sequence CKH2, CKH3, CKH1, CKH5, CKH6, CKH4, CKH8, CKH9, CKH7 turns on the switch 124 in sequence; in the third odd frame, the turn-on sequence CKH3, CKH1, CKH2, CKH6, CKH4, CKH5, CKH9, CKH7, CKH8 turn on the switch 124 in sequence; in the first even frame, use the turn-on sequence CKH1, CKH2, CKH3, CKH4, CKH5, CKH6, CKH7, CKH8, CKH9 to turn on the switch 124 in sequence; in the second even frame In the third even frame, the conduction sequence CKH3, CKH1, CKH2, CKH6, CKH4 is used to conduct the switch 124 , CKH5 , CKH9 , CKH7 , CKH8 turn on the switches 124 in sequence and so on, so as to write the corresponding data signals S1 and S2 in different turn-on sequences during different frame periods.

Therefore, the driver chip controller 112 may further include another register (not shown) for storing settings for determining how many frames pass or how many rows need to switch the conduction sequence. For example, in this embodiment, the driver chip controller 112 can output a switching signal Toggle_f (not shown) to the panel driving unit 114 to determine how many frames have passed (for example, after 1 frame time, 2 frames time or 4 frame times) to switch the conduction sequence of the switches, and output a switch switching signal Toggle_1 (not shown) to the panel driving unit 114 to determine how many rows (eg, 1 row, 2 rows, 4 rows or 8 rows) line) need to switch the conduction sequence of the switch.

In this embodiment, the source driving unit 116 drives the pixel panel 120 in a dot inversion manner. In another embodiment, the source driving unit 116 may also drive the pixel panel 120 in a line inversion manner, so that the pixel panel 120 displays an image frame corresponding to the data signal.

FIG. 3 is a schematic diagram of another implementation of the source driving unit in FIG. 1 . For convenience of illustration, FIG. 3 only shows a partial structure of the source driving unit. For example, FIG. 3 only shows one group of data channels of the source driver unit.

In this embodiment, the source driving unit 316 drives the pixel panel in a row inversion manner. The main difference from the source driving unit 116 in FIG. 2 lies in, for example, the way in which the data channel group of the source driving unit 316 raises or lowers the voltage level of the data signals provided by the multiplexers MUX3 and MUX4 .

For example, if the data signal provided by the multiplexer MUX3 has a voltage level of 1.8V, the level shifter LVS1 will pull it up to 6.5V; and if the data signal provided by the multiplexer MUX3, If its voltage level is 0V, the level shifter LVS1 will not pull up its voltage level, but keep it at 0V.

Similarly, if the data signal provided by the multiplexer MUX4 has a voltage level of 1.8V, the level shifter LVS2 will also pull it up to 6.5V; and if the data signal provided by the multiplexer MUX4 signal, its voltage level is 0V, then the level shifter LVS2 will not pull up its voltage level, and keep it at 0V.

In addition, the same or similar parts of this embodiment and the embodiment of FIG. 2 can be obtained from the description of the embodiment of FIG. 2 for sufficient teaching, suggestion and implementation description, so no more details are given here.

Figure 4 shows a pixel panel driven according to various inversion states. The symbol "+" in FIG. 4 indicates that the pixel is positive polarity, and the symbol "-" indicates that the pixel is negative polarity. Please refer to FIG. 1, FIG. 2 and FIG. 4. In this embodiment, if the driver chip 110 wants to drive pixel panels of various inversion states as shown in FIG. 4, a flexible mechanism for controlling polarity conversion is required .

Therefore, in this embodiment, the driver chip controller 112 may include a register (not shown), so that the driver chip controller 112 can control each multiplexer in the source driver unit 116 . When each multiplexer switches, the driver chip controller 112 can output a plurality of control signals en1_muxg2[0]~en1_muxg2[7] (not shown) to the source driver unit 116 to determine the polarity selection signal NCH When to turn the state is to determine whether the polarity of the data signal needs to be changed, so that the driving chip controller 112 can adaptively drive various inversion-type pixel panels in the corresponding driving mode of the panel.

In addition, the way the driver chip controller 112 will drive the pixel panel can be calculated after the conduction sequence of the switches (ie, the timing of the horizontal clock signals CKH1 - CKH9 ) and the inversion state of the pixel panel are determined.

In another embodiment, the polarity exchange of the data signals can also be realized only by exchanging the timing of the horizontal clock signals CKH1 - CKH9 . Therefore, when the timings of the horizontal clock signals CKH1 - CKH9 are exchanged, the polarity selection signal NCH does not need to be inverted. Whether the polarity selection signal NCH needs to be inverted can be determined after the timing of the horizontal clock signals CKH1 - CKH9 is determined.

In addition, the parts of this embodiment that are the same as or similar to the embodiment in FIG. 1 can be obtained from the description of the embodiment in FIG. 1 for sufficient teaching, suggestion and implementation description, so they are not repeated here.

Please refer to FIG. 1 , FIG. 2 and FIG. 5 , in this embodiment, the driver chip controller 112 of the driver chip 110 can also integrate the timing control of the two driving modes of dot inversion and row inversion. It should be noted that, compared with row inversion, the switching of the polarity selection signal NCH for dot inversion is more frequent.

In addition, the parts of this embodiment that are the same as or similar to the embodiment in FIG. 1 can be obtained from the description of the embodiment in FIG. 1 for sufficient teaching, suggestion and implementation description, so they are not repeated here.
