Embodiment 1
[0040] In this embodiment, a driving circuit 602 is described, such as figure 2 As shown, it includes: M gate drivers 201 and N source drivers 202 .
[0041] Wherein: M gate drivers 201 are connected to the display screen 902, and each gate driver in the M gate drivers 201 includes a first control pin, a second control pin, a third control pin, and a fourth control pin foot.
[0042] Further, the first control pin is used to receive the forward scan control signal, and the second control pin is used to receive the reverse scan control signal.
[0043] Further, the third control pin is connected to the fourth control pin.
[0044] like image 3 as shown, image 3 Described is a pin diagram of a gate driver, the gate driver in the background technology only has a first control pin and a second control pin, and image 3 On the basis of the original gate driver, the gate driver in the system adds two new control pins, namely the third control pin and the fourth control pin, ...
Embodiment 2
[0075] In the second embodiment, a display screen 902 is described, such as Image 6 As shown, it includes a display unit 601 , a driving circuit 602 described in Embodiment 1, a timing controller 603 and N data registers 604 .
[0076] Wherein, the driving circuit 602 is connected to the display unit 601, and the driving circuit 602 includes M gate drivers 201 and N source drivers 202, where M is an integer greater than or equal to 2, and N is an integer greater than or equal to 1.
[0077]The timing controller 603 is connected to the M gate drivers 201 and is used for generating a forward scanning control signal or a reverse scanning control signal for controlling the M gate drivers 201 .
[0078] Further, the timing controller 603 includes: a forward scan control signal pin and a reverse scan control signal pin.
[0079] Further, the forward scan control signal pin is connected to the first control pin of the first gate driver among the M gate drivers 201 . The reverse sc...

Abstract
The invention discloses a drive circuit, a display screen and electronic equipment. The drive circuit comprises M gate drivers and N source drivers, wherein the M gate drivers are connected with the display screen; each of the M gate drivers comprises a first control pin, a second control pin, a third control pin and a fourth control pin; the first control pins are used for receiving positive scanning control signals, and the second control pins are used for receiving reverse scanning control signals; the third control pins are connected with the fourth control pins; the fourth control pin of the ith gate driver is connected with the third control pin of the (i+1)th gate driver; the fourth control pin of the Mth gate driver is connected with the second control pin of the Mth gate driver, M is an integer which is more than or equal to 2, and i is an integer which is more than or equal to 1 and less than M; and the N source drivers are connected with the display screen, and N is an integer which is more than or equal to 1.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a driving circuit, a display screen and electronic equipment. Background technique [0002] TFT (Thin Film Transistor, Thin Film Field EffectTransistor) liquid crystal panel realizes image transmission through fixed gate driver scanning mode and source driver transmission mode, such as figure 1 as shown, figure 1 The 60HZ 1366*768 panel described in , the forward scanning method of the panel is from top to bottom, from left to right, so that the scanning direction of the corresponding gate driver is G1→G768, that is, scanning from top to bottom, corresponding to The transmission direction of the source driver shift register is S1→S1366, that is, scanning from left to right. [0003] It can be seen that the scanning direction of the above-mentioned panel is relatively single, and this singleness of the display direction also proposes a fixed structural design for the struct...
