Description

Active matrix display panel and driving method thereof

The present invention relates to an active matrix display panel and a driving method thereof, and more particularly to an active matrix display panel and a driving method thereof that can be applied to a bilateral scanning driver and can reduce the number of scanning channels of the scanning driver.

FIG. 1A is a block diagram of a conventional liquid crystal display 100. The conventional liquid crystal display 100 includes a scan driver 110, a data driver 120, a plurality of scan lines, a plurality of data lines, and a liquid crystal display panel 130. The liquid crystal display panel 130 includes a plurality of pixel units.

When the liquid crystal display panel 130 is developed toward a large size, the length of the scanning line of the liquid crystal display 100 may increase. Due to the RC effect on the scan line, when the scan signal of a scan line is enabled, the waveform of the actually obtained scan signal at the position on the scan line away from the scan driver is distorted.

The waveform distortion of the above-mentioned waveforms will be described by taking the waveform of the scanning signals of points A and B on the scanning line 111 as an example. FIG. 1B is a diagram showing an example of a waveform diagram of a scanning signal at point A of the scanning line 111. FIG. 1C is a diagram showing an example of a waveform diagram of a scanning signal at point B of the scanning line 111. Among them, point B is farther away from scan driver 110 than point A. When the scanning signal at point A is enabled, that is, when the scanning signal at point A is high, the open relationship in the pixel unit 131 is turned on by the scanning signal at point A, and the pixel unit 131 is connected. The pixel data transmitted from the data driver 120 through the data line is received. Similarly, when the scan signal at point B is enabled, the open relationship in the pixel unit 132 is turned on, and the pixel unit 132 receives the pixel data.

In FIG. 1B, the scan driver 110 enables the scan signal on the scan line 111 during a scan period T0. Since the point A is closer to the scan driver 110, the resistance-capacitance effect is lower, so the scan signal at point A is at a high level during the scan period T0. That is, the scan signal at point A is not distorted.

In FIG. 1C, since the point B is farther away from the scan driver 110, the RC effect is higher, so the scan signal at the point B is slowly changed from the low level to the high level during the scanning period T0. After the scanning period T0, the scanning signal at point B slowly returns to the low level.

Therefore, during the scanning period T0, the time at which the scanning signal at point B is maintained at a high level is shorter than the time at which the scanning signal at point A is maintained at a high level. Therefore, during the scanning period T0, the time during which the switch in the pixel unit 132 is turned on is shorter than the time during which the switch in the pixel unit 131 is turned on. Therefore, the storage capacitor in the pixel unit 132 is charged for a short time and cannot be charged to a predetermined level during the scanning period T0. Therefore, the luminance of the pixel unit 132 is lower than the luminance of the pixel unit 131.

Therefore, when the liquid crystal display panel 130 is developed toward a large size, the screen away from the scan driver 110 may be dark, causing a problem of uneven brightness of the screen. Therefore, the conventional architecture cannot be applied to a large-sized liquid crystal display.

FIG. 2 is a block diagram of another conventional liquid crystal display. Compared with the liquid crystal display of FIG. 1A, the liquid crystal display 200 is connected to the liquid crystal display. A first side scan driver 140 and a second side scan driver 150 are disposed on both sides of the panel 130. The first side scan driver 140 and the second side scan driver 150 send the same scan signal at the same timing. As such, in FIG. 2, point B away from scan driver 140 is closer to scan driver 150. Therefore, the scanning signal at point B is not distorted by the RC effect. In this way, the problem of distortion of the scanning signal at the position on the scanning line of FIG. 1A away from the scanning driver 110 can be improved. Further, the screen brightness of the liquid crystal display panel 130 is made uniform.

However, the liquid crystal display 200 has one more scan driver than the liquid crystal display 100. The number of scanning channels of the liquid crystal display 200 is twice the number of scanning channels of the liquid crystal display of FIG. 1A. Therefore, the liquid crystal display 200 is more expensive to produce and consumes more power when used.

In order to make the above-mentioned contents of the present invention more comprehensible, a preferred embodiment will be described below, and in conjunction with the drawings, a detailed description is as follows:

FIG. 3 is a schematic diagram of an active matrix display panel 300 of the embodiment. The active matrix display panel 300 includes scan lines S1 and S2, data lines DT, switches 310 and 320, and pixel units 330 and 340. The control terminal of the switch 310 receives a scan signal SK, the first end receives the control signal C1, and the second end is coupled to one end of the scan line S1. The control terminal of the switch 320 receives the control signal C2, the first end receives the scan signal SK, and the second end is coupled to one end of the scan line S2.

The pixel units 330 and 340 are respectively controlled by the scanning lines S1 and S2, and receive the pixel data transmitted from the data line DT when the scanning lines S1 and S2 are enabled, respectively.

In this embodiment, the switches 310 and 320 are implemented as N-type metal oxide semiconductor (NMOS) transistors. The control terminals of switches 310 and 320 are gates, and the first and second ends of switches 310 and 320 are one of the drain/source and the other.

FIG. 4 illustrates a driving method of the embodiment for driving the active matrix display panel 300. Please also refer to Figures 3 and 4. In step 410, in a first scanning period TS1, the control signal C1 is enabled, and the scanning signal SK is enabled so that the scanning line S1 can be scanned, and the control signal C2 is not enabled to keep the scanning line S2 disabled.

Graphic material.

In this embodiment, the two switches 310 and 320 are controlled to be turned on and off by the two control signals C1 and C2. The active matrix display panel 300 only needs one scanning signal SK to enable and disable the two scanning lines S1 and S2. because Therefore, the scan signal is output to the scan driver of the active matrix display panel 300 of the embodiment, and only one scan channel is required to control the two scan lines. Therefore, compared with the conventional active matrix display panel, two scanning channels are required to control two scanning lines. The active matrix display panel of the embodiment can halve the number of scanning channels of the scanning driver.

FIG. 5 is a schematic diagram of the active matrix display panel 500, the first side scan driver 610, the second side scan driver 620, and the data driver 630 of another embodiment. In this embodiment, the first side scan driver 610 outputs the scan signals SC2, SC4 and SC6, the second side scan driver 620 outputs the scan signals SC1, SC3 and SC5, and the data driver 630 outputs the pixel data.

In the present embodiment, the active matrix display panel 500 includes scan lines L1 to L6, switches SW1 to SW10, a plurality of pixel units (indicated by P), and a plurality of data lines. In the present embodiment, the switches SW1 to SW10 are N-type semiconductor transistors (NMOS). The control terminals of the switches SW1 to SW10 are gates, and the first ends and the second terminals of the switches SW1 to SW10 are respectively one of the drain/source and the other of them.

The control terminal of the switch SW1 receives the scan signal SC2, the first end of which receives the control signal P1, and the second end of which is coupled to one end of the scan line L1. The other end of the scan line receives the scan signal SC1.

The control terminal of the switch SW2 receives the control signal P2, the first end of which receives the scan signal SC2, and the second end of which is coupled to one end of the scan line L2. The control terminal of the switch SW3 receives the scan signal SC3, the first end of which receives the control signal P3, and the second end of which is coupled to the other end of the scan line L2.

The control terminal of the switch SW4 receives the scan signal SC4, the first end of which receives the control signal P1, and the second end of which is coupled to one end of the scan line L3. The control terminal of the switch SW5 receives the control signal P4, the first end of which receives the scan signal SC3, and the second end of which is coupled to the other end of the scan line L3.

The control terminal of the switch SW6 receives the control signal P2, the first end of which receives the scan signal SC4, and the second end of which is coupled to one end of the scan line L4. The control terminal of the switch SW7 receives the scan signal SC5, the first end of which receives the control signal P3, and the second end of which is coupled to the other end of the scan line L4.

The control terminal of the switch SW8 receives the scan signal SC6, the first end of which receives the control signal P1, and the second end of which is coupled to one end of the scan line L5. The control terminal of the switch SW9 receives the control signal P4, the first end of which receives the scan signal SC5, and the second end of which is coupled to the other end of the scan line L5.

Each pixel unit of the active matrix display panel 500 is controlled by one of the scan lines L1 to L6. When the pixel unit is enabled by the scan line, the pixel data transmitted by the corresponding data line is received. The pixel data is output by the data driver 630.

The operation of the active matrix display panel of Fig. 5 will be explained. FIG. 6 is a diagram showing an example of a timing chart of the signals on the scanning signals SC1 to SC6, the control signals P1 to P4, and the scanning lines L1 to L4 in FIG. In this embodiment, each of the above signals is a high level when enabled, and a low level when disabled. High level is the level that can turn on each switch, low level In order to close the level of each switch.

Please also refer to Figures 5 and 6. During the scanning period T1, the scanning signals SC1 and SC2, the control signals P1 and P4 are enabled; the scanning signals SC3 to SC7, and the control signals P2 and P3 are disabled.

The enabled scan line SC2 turns on the switch SW1, so that the control signal P1 is transmitted to one end of the scan line L1 through the switch SW1. Since the control signal P1 is enabled, the scan line L1 is enabled. In addition, the scan signal SC1 is enabled, and the scan signal SC1 is enabled by the other end of the scan line L1. Therefore, in the scan period T1, both ends of the scan line L1 are respectively enabled to receive the enable control signal P1 and the enable scan signal SC1.

During the scanning period T1, the control signal P2 is disabled, and the scanning signal SC3 is disabled, so the switches SW2 and SW3 are off. Thus, no signal can be transmitted to the scan line L2 through the switches SW2 and SW3. Therefore, the scanning line L2 is in a floating state. If the scan line is not enabled before it enters the floating state, it will remain disabled after entering the floating state. Otherwise, the scan line remains enabled. In the present embodiment, since the scan line L2 is initially disabled, the scan line L2 remains non-enabled during the scan period T1. Similarly, the scan line L4 also enters the floating state and remains disabled.

During the scanning period T1, the scanning signal SC4 is disabled, so the switch SW4 is turned off, and the control signal P4 is enabled, so the switch SW5 is turned on. Therefore, the scanning signal SC3 is transmitted to the scanning line L3 through the switch SW5. Since the scan signal SC3 is disabled, the scan line L3 is disabled during the scan period T1. Similarly, the scan line L5 is disabled.

In addition, one end of the scanning line L6 receives the non-enabled scanning signal SC7, so the scanning line L6 is also disabled.

Therefore, in the scanning period T1, the scanning line L1 is enabled, and the scanning lines L2 to L6 are disabled. The scan line L1 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

Then, during the scanning period T2, the scanning signals SC2 and SC3, the control signals P2 and P3 are enabled, and the scanning signals SC1, SC4 to SC7, and the control signals P1 and P4 are disabled.

The enabled scan signal SC2 turns on the switch SW1, so that the control signal P1 is transmitted to the scan line L1 through the switch SW1. Since the control signal P1 is disabled at this time, the scan line L1 is disabled. In addition, the scan signal SC1 is disabled, and the scan signal SC1 is input to the scan line L1 from the other end of the scan line L1, so that the scan line L1 is disabled.

The enabled control signal P2 turns on the switch SW2, and the enabled scan signal SC3 turns on the switch SW3. Therefore, the scanning signal SC2 is transmitted to one end of the scanning line L2 through the switch SW2, and the control signal P3 is transmitted to the other end of the scanning line L2 through the switch SW3. Therefore, at the scanning period T2, both ends of the scanning line L2 receive the enabled scanning signal SC2 and the enabled control signal P3. The scan line, L2, is enabled.

The non-enabled scan signal SC4 turns off the switch SW4, and the non-enabled control signal P4 turns off the switch SW5. Therefore, the scanning line L3 enters the floating state. Since the scan line L3 is disabled before entering the floating state, the scan line L3 remains non-enabled in the floating state.

Similar to the action of scanning the line L2 during the scanning period T1, the scanning line L4 is disabled in the scanning period T2. Similarly to the scanning line L3 in the scanning period T2, in the scanning period T2, the scanning line L5 enters the floating state and remains disabled. Similar to the action of the scanning line L6 in the scanning period T1, the scanning line L6 is disabled in the scanning period T2.

Therefore, in the scanning period T2, the scanning line L2 is enabled, and the scanning lines L1, L3 to L6 are disabled. The scan line L2 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

Then, during the scanning period T3, the scanning signals SC3 and SC4, the control signals P1 and P4 are enabled, and the scanning signals SC1, SC2, SC5 to SC7, and the control signals P2 and P3 are disabled. The enabled scan signal SC4 turns on the switch SW4, and the enabled control signal P4 turns on the switch SW5. Therefore, the control signal P1 is transmitted to one end of the scanning line L3 through the switch SW4, and the scanning signal SC3 is transmitted to the other end of the scanning line L3 through the switch SW5. Since both the control signal P1 and the scan signal SC3 are enabled, in the scan period T3, both ends of the scan line L3 are respectively enabled to be enabled by the control signal P1 and the scan signal SC3.

Similar to the action of the scanning line L3 in the scanning period T2, the scanning line L4 enters the floating state during the scanning period T3. Since the scan line L4 is disabled before entering the floating state, that is, during the scan period T2, the scan line L4 remains non-enabled during the scan period T3. Similar to the action of the scanning lines L5 and L6 in the scanning period T1, the scanning lines L5 and L6 are disabled in the scanning period T3.

Therefore, in the scanning period T3, the scanning line L3 is enabled, and the scanning lines L1, L2, L4 to L6 are disabled. The scan line L3 enables its corresponding pixel unit such that each enabled pixel unit receives the pixel data transmitted by the corresponding data line.

Thereafter, during the scanning period T4 to T6, the action of the active matrix display panel is the same, and will not be described herein.

In this embodiment, the active matrix display panel 500 has six scanning lines and ten switches as an example, and the practical application is not limited thereto. The active matrix display panel of the present invention may include more or fewer scan lines and cooperatively include more or fewer switches.

In this embodiment, the control signals P1 and P4 may be the same signal or different signals having the same timing. The control signals P2 and P3 can be the same signal or different signals with the same timing.

In the above embodiments, the switches 310, 320, SW1 to SW10 are implemented by using an NMOS as an example, but the practical application is not limited thereto.

The effect of the active matrix display panel of this embodiment will be described. Take scan line L3 as an example. The scan line L3 is enabled during the scan period T3, and both ends of the scan line L3 receive the enabled control signal P1 and the enabled scan signal SC3. The scan line L3 is enabled by inputting the enabled control signal and the scan signal from both ends of the scan line L3, and the signal waveform at each position on the scan line L3 is not distorted by the RC effect. Similarly, the signal waveforms on other scan lines are not distorted.

Therefore, when the active matrix display panel of the present embodiment is developed toward a large size, it does not cause various positions on the scan line because the scan line becomes long. The signal waveforms are inconsistent. Therefore, the picture brightness of the active matrix display panel of the embodiment is relatively uniform compared to the conventional liquid crystal display panel of FIG. Therefore, the image quality of the active matrix display panel of this embodiment is higher than that of the conventional liquid crystal display panel of FIG. 1A.

In addition, if the active matrix display panel of the embodiment includes N scan lines, the first side scan driver and the second side scan driver that are matched together need only configure N+1 scan channels to output scan signals, that is, The above N scanning lines can be correctly controlled. In contrast, the conventional liquid crystal display panel of FIG. 2 includes N scanning lines, and the first side scanning driver and the second side scanning driver of the conventional liquid crystal display panel respectively need to be configured with N scanning channels, that is, a total of It is necessary to configure 2×N scanning channels to correctly control the above N scanning lines.

For example, the active matrix display panel of the embodiment has six scan lines, the first side scan driver 610 is required to provide three scan channels, and the second side scan driver 620 provides four scan channels for a total of seven scan channels. The above 6 scan lines can be controlled. The conventional liquid crystal display panel, which also has six scanning lines, requires the first side scanning driver 140 and the second side scanning driver 150 to provide six scanning channels, respectively, for a total of 12 scanning channels, and the above six scanning lines can be controlled. Therefore, the active matrix display panel of the embodiment can effectively reduce the number of scanning channels of the scan driver to which it is matched, reduce the production cost, and consume power during use.

Therefore, the active matrix display panel of the present embodiment has the characteristics of low production cost, low power consumption, and better image quality.

In summary, although the present invention has been disclosed above in a preferred embodiment, It is not intended to limit the invention.
