Embodiment 1

[0096] see figure 1 , this embodiment provides a GOA circuit, including:

[0097] At least one GOA unit group 11, wherein each GOA unit group includes multiple stages of GOA units 12 connected in series;

[0098] In each of the above GOA unit groups 11, the first-level GOA unit 12 is connected to the frame start signal, and at least one boundary GOA unit 12 is connected to the control signal through the switch control unit 13, and the boundary GOA unit 12 is selected from the GOA unit group For any level of GOA units other than the first level GOA unit and the last level GOA unit, the control signal is used when it is not necessary to display the area corresponding to the boundary GOA unit 12 to the next level GOA unit 12, The switch control unit 13 is controlled to be turned off, so that the boundary GOA unit 12 to the last stage GOA unit 12 are all in a stop working state.

[0099] In this embodiment, the number of GOA unit groups is not limited, for example, it may be 1, ...

Embodiment 2

[0117] see Figure 4 , this embodiment provides a GOA circuit, including:

[0118] A GOA unit group 21, located on either side of the display device, the GOA unit group 21 includes N levels of GOA units 22 connected in series, where N is an integer > 2, wherein there are M border GOA units, and the border GOA units are selected from For any level of GOA unit in the GOA unit group except the first level GOA unit and the last level GOA unit, M is equal to the number of types of video resolution minus 1, and the number of types of video resolution is at least 2;

[0119] In the GOA unit group 21, the first-level GOA unit 22 is connected to the frame start signal STV1, and each boundary GOA unit 22 is connected to a control signal through a switch control unit 23, and the control signal is used for displaying the boundary GOA unit. 22 to the area corresponding to the last-level Nth-level GOA unit 22 of the GOA unit group, control the switch control unit 23 to turn off, so that th...

Embodiment 3

[0126] This embodiment provides a GOA circuit, including:

[0127] Two GOA unit groups are respectively located on opposite sides of the display device. Each GOA unit group includes multi-level GOA units connected in series, and the multi-level GOA units connected in series have at least one boundary GOA unit, and the boundary GOA unit Select from any level of GOA units in the GOA unit group except the first level GOA unit and the last level GOA unit, the total number of border GOA units included in the two GOA unit groups is the number of types of video resolution minus 2 , the number of video resolution types is greater than 2;

[0128] In each GOA unit group, the first-level GOA unit is connected to the frame start signal, and the border GOA unit is connected to the control signal through the switch control unit, and the control signal is used to display the border GOA unit to the GOA unit group when it is not necessary When the region corresponding to the last-level GOA u...

Abstract

The invention discloses a GOA (gate driver on array) circuit, a driving method of the GOA circuit, flexible display equipment and a display control method, and belongs to the technical field of display. The GOA circuit comprises at least one GOA unit group, wherein each GOA unit group comprises multi-level GOA units connected in series, in each GOA unit group, the first-level GOA unit is connected with a frame starting signal, in addition, at least one boundary GOA unit is connected with a control signal through a switch control unit, and the control signal is used for controlling the switch control unit to stop when the region corresponding to a range from the boundary GOA unit to the last-level GOA unit does not need to be displayed, so that the boundary GOA unit to the last-level GOA unit are respectively in a work stopping state. The partial region of a display screen is controlled not to be displayed, the power consumption of the display equipment is reduced, the non-display region and the display region are controlled not in the same plane on the flexible display equipment, the aesthetic feeling is improved, and the visual experience is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate driver on array (Gate Driver on Array, GOA for short) circuit and a driving method, a flexible display device and a display control method. Background technique [0002] At present, video files not only have a variety of formats, but also have a variety of resolutions, such as 480*360, 640*480, 1280*720, 800*600 and so on. When the display device plays video files with different resolutions, in order to make the playing picture more suitable for viewing, it usually displays black borders at the upper and lower ends of the screen or at the left and right ends, so that the middle part of the screen can play a video with a suitable aspect ratio. video. Wherein, the black frame is realized by controlling the corresponding row to be displayed in black by the corresponding GOA unit. [0003] However, for the display device, in order to match the resolution of the vide...
