Description
Technical Field
The present invention relates to a display device, and more particularly, to a driving method for increasing a refresh rate of a display device and a display device using the same.
Background
Fig. 1 is a schematic diagram of a pixel circuit of an Active-Matrix Organic Light-Emitting Diode (AMOLED) panel in the prior art. Referring to fig. 1, the pixel of the active matrix organic light emitting diode panel includes a multiplexer thin film transistor 101, a scanning thin film transistor 102, a driving thin film transistor 103, and an organic light emitting diode 104. The multiplexer thin film transistor 101 is disposed between the data line of the organic light emitting diode panel and the data driving circuit. Generally, in an organic light emitting diode panel, a multiplexer design is used to reduce the number of traces from a data driving circuit chip to a pixel, so as to reduce the area of the lower interface of the panel and reduce the pin counts (pin counts) of the data driving circuit.
FIG. 2 is a schematic diagram of a driving circuit of a multiplexer of an AMOLED panel according to the prior art. FIG. 3 is a schematic diagram of driving waveforms of a multiplexer of an AMOLED panel according to the prior art. Please refer to fig. 2 and fig. 3. When the mux1 is enabled, the data driving circuit charges the data line 201, and after the RC (resistance capacitance) on the data line 201 is fully charged, the mux1 is disabled, and the mux2 is enabled. When the mux2 is enabled, the data driving circuit charges the data line 202, and disables the mux2 after the RC (resistive-capacitive) on the data line 202 is fully charged.
After the RC of the data lines 201 and 202 are fully charged, the Scan signal Scan [ n-1] is asserted, the Scan tft 102 of the pixel is turned on, and the driving tft 103 is also turned on, so that the current (Ids) of the driving tft 103 is controlled by the data voltage, and the brightness of the light emitting is controlled.
As can be seen from the above-mentioned circuit operations of fig. 1 to 3, there are two main factors for controlling whether the pixel circuit is fully charged, the first is the time period for the multiplexing signals (mux1, mux2) to be enabled, and the second is the time period for the scan tft 102 to be turned on (turn-on). In addition, the time during which the scanning thin film transistor 102 is turned on also affects the degree of brightness compensation (mura compensation). The mura compensation circuit is not shown in the figure.
Taking fig. 2 as an example, the scanning time of one horizontal line is divided into the time when the 2 multiplexing signals (mux1 and mux2) and the scanning tft 102 are turned on, and the enabling time of the 2 multiplexing signals and the turning-on time of the scanning tft 102 cannot overlap (overlap). With the current FHD +20:9 (2220X 1080) panel, the frame rate is 60Hz, the time for one scan line is about 6.9us, the time for each multitask path to be turned on is about 2.0us, and the time for the thin film transistor for scanning to be turned on is about 2.0 us. If a high frame rate up to 120Hz is to be supported, the time for one scan line is shortened to about 3.45us, the time allocated to turn on each multiplexing path is 1us, and the time allocated to turn on the thin film transistor for scanning is about 1 us. At this time, the display panel is likely to have a phenomenon that both the data lines and the pixel circuits are not fully charged, thereby causing abnormal brightness of the display and serious brightness unevenness (mura phenomenon). Therefore, in the prior art, the design of the multiplexer is not adopted if the high frame rate is supported to 120 Hz. In order to increase the charging time, a design of all output pins is generally adopted to solve the above-mentioned abnormal display problem. However, the design of the all-out pin will increase the bottom edge, and the data driving chip must be plugged into more source driving channels (source channels), which increases the cost of the display device.

Detailed Description
Fig. 4 is a schematic diagram of a display device according to a preferred embodiment of the invention. Referring to fig. 4, the display device includes a display panel 401 and a data driving circuit 402 (not shown). The display panel 401 includes a plurality of horizontal lines 403 and a multiplexing circuit 404. Each horizontal line 403 includes a first group of pixels 405, a second group of pixels 406, a first group of scan lines 407, and a second group of scan lines 408. The first group of scan lines 407 is electrically connected to the first group of pixels 405. The second group of scan lines 408 is electrically connected to the second group of pixels 406. In this embodiment, the pixels of one horizontal line 403 are divided into an odd group of pixels 405 and an even group of pixels 406, and the two groups of pixels are respectively coupled to different scan lines.
In the example of FIG. 4, the multiplexing circuit 404 is, for example, a multiplexer having four pixel channels corresponding to one data input terminal. However, it should be understood by those skilled in the art that the multiplexing circuit 404 is merely used as an exemplary example, and the number of data inputs is determined according to the number of pins of the data driving circuit 402 when the present invention is applied. Similarly, the number of pixel channels is also determined according to the number of data lines. Here, the multiplexing circuit 404 includes a first group of pixel channels (tfts M1, M3) and a second group of pixel channels (tfts M2, M4). In this embodiment, the first group of pixels 405 is also divided into a first sub-pixel P1 and a second sub-pixel P3, which are respectively coupled to the tfts M1 and M3. Similarly, the second group of pixels 406 is also divided into a first sub-pixel P2 and a second sub-pixel P4, which are respectively coupled to the tfts M2 and M4.
The tfts M1, M3 of the first group of pixel channels are coupled to the first group of pixels 405, respectively. The tfts M2, M4 of the second group of pixel channels are coupled to the second group of pixels 406, respectively. The data driving circuit 402 is electrically connected to the data input terminal of the multiplexing circuit 404. For a better understanding of the present invention, Scan [ N-2], Scan [ N-1], Scan [ N +1], data lines are labeled D1, D2, D3, D4, respectively, and the gates of each TFT M1, M2, M3, M4 of the multitasking circuit 404 are labeled mux1, mux2, mux3, mux4, respectively. In addition, in this embodiment, an active matrix organic light emitting diode is taken as an example. While the pixel in the figure is only illustrated by a single thin film transistor, the detailed pixel circuit can refer to fig. 1. However, it should be understood by those skilled in the art that the driving circuit structure of the present invention can be applied to different types of display panels, and the present invention is not limited to the active matrix organic light emitting diode.
Fig. 5 is a waveform diagram illustrating an operation of a display device according to a preferred embodiment of the invention. Referring to fig. 4 and 5, when the display Data N is outputted, the mux1 and the mux2 are enabled sequentially, the tfts M1 and M3 are turned on sequentially, and the Data lines D1 and D3 corresponding to the first sub-pixel P1 and the second sub-pixel P3 are charged respectively (taking the configuration of fig. 1 as an example, for example, the resistance capacitors on the Data lines D1 and D3 are charged). During this period, since the Scan line Scan [ N-1] is asserted, the data voltages stored in the previous data lines D2 and D4 are transferred to the sub-pixel P2 and the sub-pixel P4, respectively. At this time, the voltage charged to the pair of scanning tfts in the subpixels P2 and P4 is not affected by the charging of the data lines D1 and D3.
Next, when the display Data N +1 is outputted, the mux3 and the mux4 are enabled sequentially, the tfts M2 and M4 are turned on sequentially, and the charging is performed on the Data line D2 corresponding to the first sub-pixel P2 and the Data line D4 corresponding to the second sub-pixel P4 respectively. During this period, Scan [ N ] is enabled, and the data voltage stored in the data lines D1 and D3 is transferred to the corresponding sub-pixels, such as the sub-pixel P1 and the sub-pixel P4, so that the scanning tfts can be charged to the voltage level without being affected by the charging of the data lines D2 and D4. In analogy, during the period of outputting the display Data N +2, the Data lines D1 and D3 are charged, and the Data voltages stored in the Data lines D2 and D4 are transferred to the corresponding sub-pixels, such as the sub-pixel P1 and the sub-pixel P4.
Compared with the prior art, the driving method provided by the invention has the advantages that the time for starting the multiplexer thin film transistor 101 and the time for starting the scanning thin film transistor 102 are not required to be completely completed in the time of one scanning line, and can be completed in the time of two scanning lines, so that the charging time of the data line can be increased, and the time for starting the scanning thin film transistor 102 can be increased.

As described above with reference to the embodiments of FIGS. 4 and 5, when Scan line Scan [ N-2] is enabled, the display Data Data N is output, and mux3 and mux4 are sequentially enabled, and TFTs M2 and M4 are sequentially turned on to charge Data lines D2 and D4, respectively.
Step S606: when the second group of scanning lines are enabled, the display voltage corresponding to the data lines of the first group of pixels of the next horizontal line is provided according to the display data. As in the previous embodiment, when the display Data N is outputted, mux1 and mux2 are sequentially enabled, TFTs M1 and M3 are sequentially turned on and charge Data lines D1 and D3 respectively, and Scan [ N-1] is enabled during the period, and the Data voltages stored in Data lines D2 and D4 are transferred to the pixels. Since the pixels are grouped, data charging and voltage transfer to the pixels can be performed simultaneously, and thus, even if the refresh rate increases, there is enough time to charge the data lines and to charge the pixels.
Fig. 7 is a flowchart illustrating the sub-steps of step S605 of the driving method for increasing the refresh rate of the display device according to a preferred embodiment of the invention. Referring to fig. 7, the step S605 includes the following steps:

Fig. 8 is a flowchart illustrating the sub-steps of step S606 of the driving method for increasing the refresh rate of the display device according to a preferred embodiment of the invention. Referring to fig. 8, the step S606 includes the following steps:
step S801: when the second group of scanning lines of the I-th horizontal line are enabled, according to the display data, in the first period of enabling the second group of scanning lines of the I-th horizontal line, the display voltage corresponding to the data line corresponding to the first sub-pixel of the first group of pixels of the I + 1-th horizontal line is provided. As shown in fig. 4 and 5, during the enabled period of Scan line Scan [ N-1], the tft M1 is turned on, and the first sub-pixel of the first group of Scan lines charges the Data line D1 according to the Data N.
Step S802: and providing a display voltage corresponding to the data line corresponding to the second sub-pixel of the first group of pixels of the I +1 th horizontal line in a second enabled period of the second group of scanning lines of the I th horizontal line. As shown in fig. 4 and 5, while the Scan line Scan [ N-1] is enabled, the thin film transistor M3 is turned on, and the second sub-pixel of the first group of Scan lines charges the Data line D3 according to the Data N.
In summary, the spirit of the present invention is to divide the horizontal lines on the panel into at least two horizontal scan lines, and the pixels on the horizontal lines are correspondingly divided into at least two groups. By means of time-sharing driving, when the previous scanning is started, the data voltage is supplied to the next pixel which is not scanned, and meanwhile, the data voltage of the previous scanning line is simultaneously injected into the pixel during scanning. Therefore, the time of a complete scanning line can be kept for charging, and the time for starting the multiplexer can be correspondingly prolonged. Therefore, the invention can increase the update rate of the display device, reduce the edge and the pin number from the driving chip to the source electrode, and maintain a certain mura compensation time.
