DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present disclosure will be completely described below in more detail in conjunction with the accompanying drawings and specific embodiments. It can be understood that, the specific embodiments described here are only intended to explain the present invention, but not to limit present invention. Besides, for ease of description, the drawings only show parts relevant to the present invention rather than all contents of the disclosure.
It is found by researchers that a conventional 3D display device includes a 3D display panel, where a lens film is adhered to a surface of the 3D display panel, and each pixel includes two sub-pixels which are configured for transmitting an image data signal for the left eye and an image data signal for the right eye, respectively; thus, in 3D display mode the image data signals are processed by an image processing system such that the image data signals transmitted by the two sub-pixels are different, and in 2D display mode, the image data signals are processed by the image processing system such that the image data signals transmitted by the two sub-pixels are identical. Therefore, a specialized image processing system is needed to process the image data signals, causing inconvenience for mutual conversion between the 3D display mode and the 2D display mode.
Technical solutions of the present disclosure are illustrated below by specific examples of embodiments, and it is noted that:
1. For scanning of each frame in a gate driving circuit, each stage of shift registers (which includes all of the first to eighth shift registers) needs to be reset once before scanning and cleared once after scanning. The reset before scanning means that an output terminal of each shift register is brought down to a low electrical potential before the shift register is scanned, in order to clear the shift register, i.e. the reset before scanning ensures that the output terminal of the shift register is always maintained at a low electrical potential before the shift register is scanned, thus ensuring good quality of the displayed image. The clearance after scanning means that the output terminal of the shift register is brought down to a low electrical potential after the shift register is scanned (i.e., after a gate driving signal is outputted from the shift register), thus ensuring that the output terminal of the shift register is maintained at a low electrical potential after the shift register is scanned, to avoid interference with the displayed image and prepare for the next scan.
2. Both a first gate driving circuit and a second gate driving circuit are applicable to a forward scan and a backward scan. For ease of the description, both the first gate driving circuit and the second gate driving circuit are for instance described as being used for the forward scan in embodiments, but the embodiments of the present invention are not limited thereto. In the present embodiment, first to ninth transistors T1 to T9 are N-channel Metal Oxide Semiconductor (NMOS) transistors, but in other embodiment, the first to ninth transistors T1 to T9 may alternatively be P-channel Metal Oxide Semiconductor (PMOS) transistors, which is not specifically limited by the embodiments of the present invention.
3. In the embodiments of the present invention, the TFT array substrate is not limited to be used in a Liquid Crystal Display (LCD), an Organic Light Emitting Display (OLED) or an electronic paper. In the embodiments of the present invention, the TFT array substrate is not limited to an amorphous silicon TFT array substrate, a Low Temperature Poly Silicon (LTPS) TFT array substrate or an oxide TFT array substrate.
4. In the embodiments of the present disclosure, first to eighth initial transistors, first to sixteenth clock transistors, and first to second pre-scan reset transistors are not limited to N-channel Metal Oxide Semiconductor (NMOS) transistors or P-channel Metal Oxide Semiconductor (PMOS) transistors. For ease of the description, the first to eighth initial transistors, the first to sixteenth clock transistors, and the first to second pre-scan reset transistors are described as N-channel Metal Oxide Semiconductor (NMOS) for example in the following various embodiments and accompanying drawings.
5. In the embodiments of the present invention, internal circuit structures and driving processes of the first to eighth shift registers, voltage ranges of first to sixteenth clock signals, voltage ranges of first to eighth second initial signals, waveforms of first to sixteenth clock signals, and voltage ranges and waveforms of first to second pre-scan reset signals are known in the art, and will not be discussed repeatedly in the present embodiment.
