Embodiment Construction

[0056] In the array substrate and its driving method, flexible display device, and electronic device according to the embodiments of the present invention, the driving unit determines the number of real data driving sub-signals in the data driving signal according to the number of thin film transistors connected to the data line, which can meet the data line connection requirements. The number of thin film transistors varies with the driving requirements of the array substrate, and has better flexibility.

[0057] It can be understood that, in the specific embodiment of the present invention, "first" and "second" mean that they are not equal when comparing the numerical relationship, and the mutual positional relationship is relative and not specific. For example: the first number is not equal to the second number; if one data line A can be called the first data line, and another data line B can be called the second data line, relatively speaking, the data line B can also be ca...

Abstract

The invention discloses an array substrate, a driving method of the array substrate, a flexible display device and an electronic device. The array substrate comprises an array layer. The array layer comprises a plurality of data lines, a plurality of grid lines and thin film transistors, wherein the data lines and the grid lines intersect on the flexible substrate to form a plurality of sub-pixel regions. The thin-film transistors are arranged in the sub-pixel regions and connected with the corresponding data lines and the corresponding grid lines. The array substrate further comprises driving units used for outputting driving signals to the corresponding data lines connected with the driving units. Corresponding to the corresponding data line, each driving unit comprises a signal generation sub-unit and a selection sub-unit, wherein the signal generation sub-unit is used for generating an original data driving signal which comprises a real data driving sub-signal for driving a sub-pixel and a virtual data driving sub-signal, and the selection sub-unit is used for screening out the real data driving sub-signal from the original data driving signal and outputting the real data driving sub-signal to the corresponding data line so as to drive the sub-pixel. According to the array substrate, the driving method of the array substrate, the flexible display device and the electronic device, driving flexibility of the array substrate is improved.

Description

technical field [0001] The invention relates to flexible display technology, in particular to an array substrate and its driving method, a flexible display device and electronic equipment. Background technique [0002] Flexible displays refer to a class of flexible substrates that can be manufactured into ultra-thin, ultra-large, and bendable display devices or display technologies. The main features of flexible displays can be described in three words: thin, light, and soft. [0003] The flexible substrate in the prior art is generally divided into two regions: one part is a non-bending region and the other is a bendable region, such as figure 1 As shown, the position of the array substrate 1 where the drive unit 4 is provided is a non-bendable area, and the drive unit 4 is connected to the data line 2 and the gate line 3 to drive the thin film transistor TFT5 provided in the panel. [0004] Such as figure 1 As shown, in the prior art, the data lines 2 and the gate lines...
