Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 9, in the present embodiment, a voltage variation of the sub-pixel 1 is illustrated. Taking the first white line as an example, Gn +3 is the first gate line of the white frame (G1, G2, G3, G4 …), Gn +2 is the previous gate line of Gn +3, Gn +1 is the previous gate line of Gn +2, and Gn is the previous gate line of Gn + 1. During time t1, Gn +3 is turned on, and Gn +2 transmits sub-pixel 1 data of 127 gray scales, and since Gn +3 is turned on, the voltage on the pixel on the first gate line of the white portion is 127 gray scales. The VGH voltage to open the gate line is typically 15V and the low voltage to close the gate line is typically-15V, which is done to ensure that Vgs (the voltage of the gate relative to the source) is on at or above 10V (the TFT switch 2 is on with a large current) and off at or below-10V (the TFT switch 2 is not prone to leakage). The voltage on the electrode of the sub-pixel 1 at time t2 is about to change from 127 gray levels to 255 gray levels, and the absolute value of the voltage on the source line (S1, S2, S3 …) is 5V.
Referring to FIG. 4, for the source line and sub-pixel 1 electrode connected to positive polarity, the voltage on the source line is +5V, and the voltage on the sub-pixel 1 electrode is +3V (assuming that the absolute value of 127 gray-scale voltages is exactly 3V). In the TFT switch 2 of fig. 3, one electrode of the TFT switch 2 connected to the source line is the drain, and the electrode of the sub-pixel 1 is the source. The Vgs of the TFT switch 2 is 15V-V, and since +5V on the source line charges the sub-pixel 1 electrode, the sub-pixel 1 electrode voltage V gradually increases from +3V to +5V, and in this case, the Vgs changes from 12V → 10V. For the source line connected to negative polarity and subpixel 1 electrode, the voltage on the source line is-5V and the voltage on subpixel 1 electrode is-3V (assuming 127 gray scale voltages are exactly 3V in absolute value). In the TFT switch 2 in fig. 3, one electrode of the TFT switch 2 connected to the source line at this time is the source, the electrode of the subpixel 1 is the drain, and the electrode of the subpixel 1 discharges to the source line. Since the Vgs of the TFT switch 2 is 15V-V source line, and the voltage on the source line is always-5V, the Vgs of the TFT switch 2 connected with negative polarity is 15V- (-5V) — 20V, and is not changed during the discharge of the electrode of the sub-pixel 1 to the source line. The variation of Vgs for positive and negative source lines is shown in fig. 4. The second white line is generated in a similar process to the first white line, and will not be described here.
Referring to fig. 5, the second white line Vgs is analyzed. For the positive source line (refer to data transmission in FIG. 3), at time t1, the data on the source line in the front 3 lines is + 255 gray-scale data, i.e., the voltage on the source line is +5V, and the voltage on the sub-pixel 1 electrode is also +5V, and at time t2, the source line is to transmit the correct + 127 gray-scale data to the sub-pixel 1 electrode. At this time, since the electrode of the subpixel 1 is the drain, the electrode connected to the source line is the source, and the voltage on the source line is + 127 gray-scale data in the second and following portions, Vgs of the TFT switch 2 connected to the positive source line is 15V-3V-12V and is not changed within one frame. However, for the TFT switch 2 connected to the negative source line, the voltage on the sub-pixel 1 electrode is-5V at time t1 (the first 3 data is-5V white data), the voltage on the source line is-3V at time t2, and only then the correct-3V sub-pixel 1 data is transmitted to the sub-pixel 1 electrode (-5V), Vgs of the TFT switch 2 is 15V- (-5V) 20V, and when the last sub-pixel 1 electrode is charged to-3V, Vgs becomes 15V- (-3V) 18V, and during the charging process to the sub-pixel 1, Vgs is gradually decreased, and the change trend is as shown in fig. 5.
The above analysis of the horizontal crosstalk occurring in the display panel with the general structure shows that, due to the different Vgs, the corresponding Ids will not be the same, and thus the charging capabilities of the TFT switches 2 will not be the same, which will result in that the coupling effects of the sub-pixel 1 electrode to the VCOM electrode cannot cancel each other out, i.e. the sub-pixel 1 with negative polarity will couple VCOM downwards with a greater capability than the sub-pixel 1 with positive polarity to couple VCOM upwards. Resulting in the overall VCOM shifting downward so that white lines appear at the 127 gray scale and white boundary. The coupling effect of positive and negative polarities to VCOM under the same data (such as full gray scale or full white) is also the same, but since the absolute value of the voltage charged to the sub-pixel 1 electrode is substantially the same, the coupling effect to VCOM is very small, and thus no abnormal phenomenon occurs.
Referring to fig. 6, in the present embodiment, a display screen structure is provided, including: a plurality of sub-pixels 1, TFT switches 2, and a plurality of source lines, although a driving unit may be further included in some embodiments; the plurality of sub-pixels 1 are arranged in a column, and the sub-pixels are arranged in an RGB manner, but may also be arranged in an RGBW manner. Each sub-pixel 1 comprises a TFT switch 2, the output end of the TFT switch 2 is connected with the sub-pixel 1, the input end of the TFT switch 2 is connected with the source line, and the control end of the TFT switch 2 is connected with the gate line; each row of the sub-pixels 1 comprises an upper gate line and a lower gate line, each sub-pixel 1 in each row is connected with one gate line through one TFT switch 2, the sub-pixels 1 with the same polarity in the same row are connected with the same gate line, the polarities of two adjacent sub-pixels 1 are different, and the sub-pixels 1 with different polarities are respectively connected with one gate line; one side of each column of the sub-pixels 1 is provided with one source line, the polarities of the sub-pixels 1 in the same column are the same, the sub-pixels 1 are connected with one source line through one TFT switch 2, the gate lines connected with the sub-pixels 1 in the same column are positioned on the same side of the row, and the colors of the sub-pixels 1 connected with each source line are the same. Specifically, each row of sub-pixels 1 is driven by two gate lines, and each source line is connected to only one color of sub-pixel 1, in this embodiment, the odd and even gate lines drive the positive and negative sub-pixels 1 respectively. In the present embodiment, the odd gate lines drive the positive sub-pixel 1 and the even gate lines drive the negative sub-pixel 1 as an example, in practical operation, the odd gate lines may drive the negative sub-pixel 1, and the even gate lines may drive the positive sub-pixel 1. In this embodiment, the on voltage VGH and the off voltage VGL of the TFT switch 2 on the odd-numbered gate lines (only the positive subpixel 1 is connected) are set to 18V and-10V (originally, VGH is 15V, and VGL is-15V), and the on voltage VGH and the off voltage VGL of the TFT switch 2 on the even-numbered gate lines (only the negative subpixel 1 is connected) are set to 10V and-15V (originally, VGH is 15V, and VGL is-15V). As can be seen from the timing chart of the embodiment shown in fig. 7, the structure of the present invention has the following features: the gate lines controlling each row of sub-pixels 1 need to be opened simultaneously, namely G1 and G2 are opened simultaneously, G3 and G4 are opened simultaneously, Gn and Gn +1 are opened simultaneously, Gn +2 and Gn +1 are different in a certain time (the real charging time of the sub-pixels 1), namely G3 and G2 are also different in a certain time, G5 and G4 are also different in a certain time, and the like. The reason for this is that the positive and negative subpixels 1 in each row are connected to different gate lines, the gate lines are turned on simultaneously and do not interfere with data transmission, and data transmitted by the source lines does not need to be processed as in the case of a normal display. Namely, a display screen structure driving method is provided, which comprises the following steps: simultaneously opening two gate lines on a row of sub-pixels 1; during the gate line is open; the driving unit transmits a signal to the connected sub-pixel 1 through the source line; simultaneously opening two grid lines on the sub-pixel 1 in the next row at a certain time interval; during the gate line is open; the driving unit transmits a signal to the connected sub-pixel 1 through the source line; the above steps are cycled to drive the sub-pixels 1 of each row. Above-mentioned technical scheme from the structural elimination horizontal crosstalk phenomenon, no matter in the display screen structure how the conduction current of TFT switch 2 changes, can not influence the display effect of display screen structure, the horizontal crosstalk problem can not appear. Meanwhile, the cost for changing the manufacturing process is reduced, and the display quality of the display screen is improved. Through the design of a special structure of the LCD display screen, Vgs of TFT switches 2 respectively driving the sub-pixels 1 with positive and negative polarities tends to be consistent, so that the sub-pixels 1 with positive and negative polarities are ensured to be charged consistently, and the consistent charging of the sub-pixels 1 can be understood as that the absolute values of the sub-pixels 1 with positive and negative polarities are the same as that of VCOM.
Referring to fig. 8, the improvement of the first white line (r) in the display screen structure is analyzed: since VGH of the odd gate line (only the positive subpixel 1 is connected) is 18V and VGL is-10V in this embodiment, VGH of the even gate line (only the negative subpixel 1 is connected) is 10V and VGL is-15V. The Vgs of the TFT switch 2 connected to the negative sub-pixel 1 on the corresponding first white line is 10V- (-5V) 15V at Vgs, and does not change in one frame, while the Vgs of the TFT switch 2 connected to the positive sub-pixel 1 is 18V-3V 15V at first, and then 18V-5V 13V at the sub-pixel 1 electrode charged to +3V at +5V on the source line. Therefore, the difference of Vgs of positive and negative polarities is greatly reduced, so that the Ids difference is reduced, and the charging capacities of the sub-pixels 1 of the positive and negative polarities tend to be consistent. For the first white line, before improvement, the Vgs difference of the TFT switch 2 connected to the positive sub-pixel 1 is Vgsmin-20V-12V-8V (see fig. 4), and the Vgs difference of the TFT switch 2 connected to the negative sub-pixel 1 is Vgsmax-20V-10V (see fig. 4). After the improvement of the present invention, the Vgs difference of the TFT switch 2 connected to the positive sub-pixel 1 is Vgsmin-15V-0V (see fig. 8), and the Vgs difference of the TFT switch 2 connected to the negative sub-pixel 1 is Vgsmax-15V-13V-2V (see fig. 8). After the Vgs difference value of the positive polarity and the negative polarity is improved, the coupling of the positive polarity sub-pixel 1 and the negative polarity sub-pixel 1 to VCOM is also improved, so that the coupling effects of the positive polarity sub-pixel 1 and the negative polarity sub-pixel 1 to the VCOM are mutually counteracted or reduced, the display abnormity can not be seen by human eyes, and the abnormal white line can not be identified by the human eyes. The same positive and negative polarity coupling effect on VCOM still exists and the patent aims to reduce this coupling effect.
Referring to fig. 9, the improvement of the second white line (c) in the display screen structure is analyzed: before improvement, the Vgs difference of the TFT switch 2 connected to the positive sub-pixel 1 is Vgsmin-20V-12V-8V (see fig. 4), and the Vgs difference of the TFT switch 2 connected to the negative sub-pixel 1 is Vgsmax-18V-12V-10V (see fig. 5). After the improvement of the present invention, the Vgs difference of the TFT switch 2 connected to the positive sub-pixel 1 is Vgsmin-15V-0V (see fig. 9), and the Vgs difference of the TFT switch 2 connected to the negative sub-pixel 1 is Vgsmax-15V-13V-2V (see fig. 9). As explained in fig. 8, the second white line disappears and the display screen is abnormally removed.
It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
