Embodiment 2

[0058] Embodiment 2 introduces the driving method of this patent with the sub-pixel data transmission on S1 (please refer to Figures 9 to 14 ): G1 is turned on, when SW1 is turned on, S1 transmits R sub-pixel data (1) to D1 in the plane through SW1, SW1 is closed, and when SW2 is opened, S1 transmits R sub-pixel data (2) to D3, SW1, When SW2 is closed and SW3 is opened, S1 transmits R sub-pixel data (3) to D7 in the plane through SW3; G2 is opened, and when SW1 is opened, S1 transmits B sub-pixel data (4) to D1 in the plane through SW1, SW1 is closed, and SW2 When it is turned on, S1 transmits G sub-pixel data ⑸ to D3 in the plane through SW2, SW1 and SW2 are closed, and when SW3 is opened, S1 transmits B sub-pixel data ⑹ to D7 in the plane through SW3; when G3 is turned on, SW1 is turned on , S1 transmits R sub-pixel data⑺ to D1 in the plane through SW1, when SW1 is closed, and SW2 is opened, S1 transmits R sub-pixel data ⑻ to D3 in the plane through SW2, SW1 and SW2 are clo...

Embodiment 3

[0068] Embodiment 3, using the Demux+HSD structure to reduce the source line of the IC output, this patent chooses the 6dot driving method (repeated transmission according to the data polarity of ﹢﹢﹢﹢﹢﹢→﹣﹣﹣﹢﹢) to achieve 1Dot (﹢ →﹣The data polarity is transmitted repeatedly) Inversion-driven Dot display effect can save the power consumption of the pure color screen of this type of display.

Abstract

The invention discloses a special full screen architecture, which comprises a plurality of pixel units and three Demux lines, and is characterized in that each pixel unit comprises a plurality of sub-pixels, a plurality of gate lines, eighteen data lines and six source lines. Wherein each pixel unit comprises a plurality of sub-pixels, the sub-pixels of each pixel unit are arranged in an array andcomprise a plurality of rows of sub-pixels, the sub-pixels of each pixel unit are divided into eighteen columns of sub-pixel pairs, and each column of sub-pixel pair comprises two columns of sub-pixels. A data line is arranged in the middle of each column of sub-pixel pairs, each data line is connected with a TFT switch, the total number of the TFT switches is eighteen, and all the TFT switches are divided into three groups. Each row of sub-pixels comprises an upper gate line and a lower gate line. According to the technical scheme, the number of the source lines is greatly reduced, the length of the Y axis is reduced, the manufacturing cost is saved at the moment, meanwhile, the power consumption during display is reduced, and the display quality of the display screen is improved.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a special full-screen architecture and a driving method. Background technique [0002] Narrow bezel and full-screen display designs have become the mainstream. With the wide spread of display screens, from the perspective of screen-to-body ratio, the screen-to-body ratio of the first-generation iPhone in 2007 was only about 50%. The ratio continues to increase, but not by much. In existing display screens, the Y-axis length of the driving unit is an important factor affecting a full screen or a narrow bezel screen. In the existing display screen, one source line (source line) of the IC corresponds to one data line (data line) in the plane, and one data line of the display screen controls a kind of sub-pixel, resulting in too many source lines, so that the drive unit If the Y axis cannot be reduced, the power consumption of the display screen is increased, and at the same time, th...
