The pixel unit includes a plurality of sub-pixels, and the sub-pixels of the pixel unit are arranged in an array including multiple rows of sub-pixels. The sub-pixels of each pixel unit are divided into twelve columns of sub-pixel pairs, and each column of sub-pixel pairs includes two columns of sub-pixels. The starting data line is located on the left side of the pixel unit, and the starting data line (the starting data line is the data line that can be connected to the source line without going through the Demux line) is used to connect the first column of the first pixel unit. A sub-pixel connected by a data line. A data line is arranged between each column of sub-pixel pairs, and each data line is connected with a TFT (Thin Film Transistor, thin film transistor) switch, and there are twelve TFT switches in total. The output end of the TFT switch is connected with the data line, and all the TFT switches are divided into two groups. According to the column order, the positions in the first, second, fifth, sixth, ninth and tenth columns are divided into a group, and the positions in the third, fourth, seventh, and tenth columns are divided into a group.

Connect with the data cable.

The above technical solution saves the power consumption of the display screen. Due to the Demux 1:2+HSD structure, the display screen only needs 1/4 of the number of Source Lines, which makes the driver unit (IC) do not need more devices, saving At the same time, the Y-axis of the IC has become narrower, so that the display can be applied to display designs that are close to full screen.

In the present application (the first embodiment and the second embodiment), the display screen structure further includes a driving unit, and the driving unit is connected to a plurality of the source lines. Since the design method of Demux is adopted after coming out of the driving unit, the number of source lines in the present invention will be reduced. When the source line is connected to the start data line in the plane through the TFT switch, the HSD method is used to align the sub-pixels. The arrangement design greatly reduces the number of source lines.

In the present application, a plurality of sub-pixels are sequentially arranged in an array in the manner of R (red), G (green), and B (blue). In some embodiments, the sub-pixel arrangement can also be in other arrangement forms, such as R, B, G, R, B, G . . . arrangement, or W (white) can also be added to perform a similar arrangement.

The start data line D1 on the far left of the display screen (the start data line is a data line that is not connected to the source line through the Demux line) is connected to the R sub-pixel and the G sub-pixel, and D1 is not connected to the Demux switch. FIG. 1 shows one pixel unit, and a plurality of pixel units can be arranged neatly in the display screen of this structure, and the number of pixel units can be selected according to the resolution of different display screens. When the pixel units are arranged in multiple arrays, the rightmost part ( D13 ) of FIG. 1 is connected to the leftmost part of FIG. 2 , that is, the Data Line is actually the same root. The left side of the first pixel unit is provided with a start data line D1 (only one alone), the start data line D1 is not arranged in an array, and the data lines (D2, D3, D4...Dm) are arranged in an array. It should be further noted that the first data line in the pixel unit located in the middle of the display area and the last data line of the previous pixel unit are the same data line. The connection between the first data line in the middle pixel unit and the sub-pixels in the pixel unit is the same as the connection between the initial data line and the sub-pixels.

S2 will first pass through Demux1 and Demux2, and then connect to D2 and D4 in the plane respectively. S3 will first pass through Demux1 and Demux2, and then connect to D3 and D5 in the plane respectively. S4 will first pass through Demux1 and Demux2, and then connect to the plane respectively. D6 and D8 in the inner surface are connected, S5 will first pass through Demux1 and Demux2, and then connect with D7 and D9 in the inner surface respectively. S6 will first pass through Demux1 and Demux2, and then connect with D10 and D12 in the inner surface respectively, and S7 will first pass through Demux1. After and Demux2, connect with D11 and D13 in the plane, respectively.

That is, the TFT switches in the first column of sub-pixel pairs (through D2) and the TFT switches in the third column of sub-pixel pairs (through D4) are respectively connected to the second source line (S2); the TFTs in the second column of sub-pixel pairs The switch (through D3) and the TFT switch of the fourth column of sub-pixel pairs (through D5) are respectively connected to the third source line (S3); the TFT switch of the fifth column of sub-pixel pairs (through D6) and the seventh column of sub-pixels The pair of TFT switches (through D8) are respectively connected to the fourth source line (S1); the TFT switches in the sixth column of sub-pixel pairs (through D7) and the TFT switches of the eighth column of sub-pixel pairs (through D9) are respectively connected to The fifth source line is connected; the TFT switch (via D10) of the sub-pixel pair in the ninth column and the TFT switch (via D12) of the sub-pixel pair in the eleventh column are respectively connected to the sixth source line; in the tenth column The TFT switch of the column sub-pixel pair (through D11 ) and the TFT switch of the twelfth column of sub-pixel pair (through D13 ) are respectively connected to the seventh source line ( S7 ).

Please refer to FIG. 1 and FIG. 2. In the first embodiment, take the data transmission of S2 as an example: when G1 is turned on and Demux1 is turned on, S2 is connected to D2 in the plane through Demux1, and the sub-connector that is connected to both D2 and G1 The pixel is R sub-pixel①, so S2 first transmits R sub-pixel ① data; when G1 is still open and Demux2 is open, S2 is connected to D4 in the plane through Demux2, and the sub-pixel connected to both G1 and D4 is G sub-pixel ②, at this time S2 transmits G sub-pixel ② data; when G2 is turned on and Demux1 is turned on, S2 is connected to D2 in the plane through Demux1, and the sub-pixel connected to both D2 and G2 is B sub-pixel ③, Therefore, S2 transmits the data of B sub-pixel ③; when G2 is still open and Demux2 is open, S2 is connected to D4 in the plane through Demux2, and the sub-pixel connected to G2 and D4 is R sub-pixel ④, at this time S2 The R sub-pixel ④ data is transmitted.

Please refer to FIG. 2. In Embodiment 1, the data transmission of other Source Lines in line) and Demux's transmission waveforms are the same, and the transmission principle is the same as that of S2, so I won't repeat them here.

Please refer to FIG. 2. In the first embodiment, due to the particularity of S1, the data transmission timing of S1 is specially drawn. When G1 is turned on and Demux1 is turned on, there is no sub-pixel connection on S1 (ie D1). Data is not transmitted, that is, Data is empty; when G1 is still open and Demux2 is open, there is no sub-pixel connection on S1 (D1), and Data is not transmitted at this time, that is, Data is empty; when G2 is open, Demux1 is open, both with S1 (D1) is connected, and the sub-pixel connected to G1 is G sub-pixel. At this time, G sub-pixel data is transmitted; G2 is still open, and when Demux2 is open, since S1 does not pass through the TFT switch of Demux, only one kind of sub-pixel is connected. At this time, the G sub-pixel data is still transmitted.

Please refer to Figure 2, (1) is the falling edge time of the Gate wrapped by the Data, this time must be present, so as to prevent the wrong charging of the data in the next line when the Gate is trailing, (2) the falling edge time of the Demux wrapped by the Data , this time is also necessary to prevent the influence of the data transmitted when Demux2 is turned on to when Demux1 is turned on. For example, S2 transmits the data of G sub-pixel ② when G1 is turned on and Demux2 is turned on. If Demux1 is trailing, that is, Demux1 has not been completely closed, but at this time, R sub-pixel ① is no longer transmitting (does not wrap the trail of Demux1) , then the data of G sub-pixel ② will also be transmitted to the Data Line controlled by Demux1, that is, color mixing occurs.

Referring to FIG. 3 , in the second embodiment, in order to realize that when the sub-pixels in the same column are driven in sequence by gate lines, the same source electrode has sub-pixels of different colors. Hereby, the same data line is used to connect the sub-pixels in different columns in the sub-pixel pair in the same column in two adjacent rows. For example, D4 is connected to the sub-pixel (2) in the first row. In the first embodiment, D4 is connected to the sub-pixel directly below the sub-pixel (2) in the first row in the second row. In the second embodiment, it is not is to connect the sub-pixels (8), so that the source line connected to D4 can transmit more types of sub-pixels. Other data lines can also be of similar variations.

Specifically, D1-D13 are also in-plane data lines (Data Lines), and S1-S7 are source lines (Source Lines) coming out of the driving unit (IC). The starting data line D1 (source line S1) on the far left of the display screen is connected to the R sub-pixel and the G sub-pixel, D1 is not connected to the Demux switch; It is connected to D4 in the plane; S3 is connected to D3 in the plane through the TFT switch of Demux1, S3 is connected to the D5 in the plane through the TFT switch of Demux2; The TFT switch is connected to the in-plane D8; S5 is connected to the in-plane D7 through the TFT switch of Demux1, S5 is connected to the in-plane D9 through the TFT switch of Demux2; S6 is connected to the in-plane D10 through the TFT switch of Demux1, and S2 is connected through The TFT switch of Demux2 is connected to the in-plane D12; the S7 is connected to the in-plane D11 through the TFT switch of Demux1, and the S7 is connected to the in-plane D13 through the TFT switch of Demux2.

Please refer to FIG. 3 and FIG. 4. In the second embodiment, FIG. 3 shows one pixel unit, and a plurality of pixel units can be arranged neatly in the display screen of this structure, which can be selected according to the resolution of different display screens. The number of pixel units. When the pixel units are arranged in multiple arrays, the rightmost part of FIG. 3 is connected to the leftmost part of FIG. 4 , that is, the Data Line is actually the same root. A start data line D1 is provided on the left side of the first pixel unit, the start data line D1 is not arranged in an array (a single one), and the data lines (D2, D3, D4...Dm) are arranged in an array.

Referring to FIG. 3 , in the second embodiment, the polarities of adjacent pixels are opposite, that is, the display effect is the Dot display effect, and the display effect of the Dot can achieve the best visual effect of the display screen. In this type of display screen, the present application adopts the driving mode of ColumnInversion to realize the display effect of Dot, which saves the power consumption of the display screen. And because of the use of Demux 1:2+HSD structure, the display screen only needs 1/4 of the number of Source Lines, which makes the IC do not need more devices, saves costs, and the Y-axis of the IC also becomes narrower.

Please refer to FIG. 3 , in the second embodiment, for S1, when G1 is turned on, since the sub-pixel on S1 is not connected to G1, and Demux1/Demux2 is turned on, S1 does not transmit sub-pixel data at this time, that is, it is empty; When G2 is turned on and Demux1 is turned on, G sub-pixel data is transmitted on S1 ①, and when Demux2 is turned on, G sub-pixel data is still transmitted on S1; At this time, R sub-pixel data is still transmitted on S1; when G4 is turned on, since the sub-pixel on S1 is not connected to G4, when Demux1/Demux2 is turned on, S1 does not transmit sub-pixel data at this time. The Data on the S1 will repeatedly transmit the data in the display screen with the regularity explained above.

Please refer to FIG. 3, in the second embodiment, the process of Demux+HSD data transmission is introduced with the data transmission of S2, and the data transmission of other Source Lines (except the Source Line on the leftmost and left and right sides of the display screen) is similar to that of S2: When G1 is open and Demux1 is open, S2 transmits R sub-pixel data (1) to D2 in the plane, Demux1 is closed, and when Demux2 is open, S2 transmits G sub-pixel data (2) to D4 in the plane; when G2 is open, Demux1 When open, S2 transmits B sub-pixel data (3) to D2 in the plane, Demux1 is closed, when Demux2 is open, S2 transmits R sub-pixel data (4) to D4 in the plane; when G3 is open and Demux1 is open, S2 transmits R sub-pixel data (5) is sent to D2 in the plane, Demux1 is closed, and when Demux2 is open, S2 transmits G sub-pixel data (6) to D4 in the plane; when G4 is open and Demux1 is open, S2 transmits G sub-pixel data ( 7) For D2 in the plane, Demux1 is closed, and when Demux2 is open, S2 transmits B sub-pixel data (8) to D4 in the plane. By analogy, the data transmission process of S3 to S7 is similar to that of S2, but the order of the transmitted data is different.

Please refer to FIG. 4. In the second embodiment, the rightmost Dm-12 of FIG. 4 is connected to the leftmost of FIG. 5. FIG. 4 is just the repeated sequence of FIG. The pixel unit appears.
