Problems solved by technology

However, when scanning row by row, the charging time of the first row of sub-pixels to display data images only takes half of the row scanning time, and the other half of the row scanning time is used for brightness compensation or charging of black and gray data for the second row of sub-pixels. The charging time of normal display pixels is less; at the same time, the signal needs to be switched every half of the row scanning time, resulting in increased frequency changes of gate drive and data line drive, and increased power consumption of the module

Embodiment 1

[0030] An image display device 1 provided by an embodiment of the present invention, such as figure 1 shown, including:

[0031] The image display panel 10 is used for displaying 2D images or 3D images by a plurality of combined pixels.

[0032] Each combined pixel in the image display panel 10 includes a first row of sub-pixels, and a second row of sub-pixels located below the first row of sub-pixels and forming a combined sub-pixel together with the first row of sub-pixels, and for each row of combined For a pixel, the first gate wiring is connected to the first row of sub-pixels, and the second gate wiring is connected to the second row of sub-pixels.

[0033] It should be noted that a plurality of combined pixels form the image display panel 10 according to m rows and n columns, and each row of sub-pixels includes the first row of sub-pixels and the second row of sub-pixels. In this implementation, the transmission unit is used to transmit 2D display data and 3D display d...

Embodiment 2

[0055] The image display method provided by the embodiment of the present invention is used to drive an image display device. The display device includes m columns and n rows of combined sub-pixels, each combined pixel includes a first row of sub-pixels, and sub-pixels located in the first row Below, and together with the first row of sub-pixels, the second row of sub-pixels that constitute the combined sub-pixels, and for each row of combined pixels, the first gate wiring is connected to the first row of sub-pixels, and the second gate wiring is connected to the second row of sub-pixels pixels, such as figure 2 shown, including the following steps:

[0056] It is worth pointing out that there is no sequence relationship between the following steps S101 and S102, and they can be performed simultaneously or successively. Wherein, if it is necessary to switch from the 2D image mode to the 3D image mode, it can be performed in the order of S101 and S102.

[0057] It should be n...

Abstract

The embodiment of the invention provides an image display device and an image display method, relating to the field of display devices, and being capable of increasing the charging time and reducing the switching frequency of drive data in the process of driving the display device. The image display method is used for driving the display device, the display device comprises m rows and n lines of combined pixels, each combined pixel comprises a first line of sub-pixels and a second line of sub-pixels (the second line of sub-pixels is arranged below the first line of sub-pixels, and constitutes the combined pixel with the first line of sub-pixels), a first grid lead is connected with the first line of sub-pixels, a second grid lead is connected with the second line of sub-pixels, and while the display device is driven in a 2D (two-dimensional) image mode, the first lines of sub-pixels and the second lines of sub-pixels of each line of combined pixels all receive display data; and when the display device is driven in a 3D (three-dimensional) image mode, the first lines of sub-pixels of each line of combined pixels receive data, and the other liens of sub-pixels of each line of combined pixels do not receive data. The method disclosed by the embodiment of the invention is applied to the driving of image display devices.

Description

technical field [0001] The invention relates to the field of image display, in particular to an image display device and an image display method. Background technique [0002] Display device is an important interface between human and machine. In the early days, CRT (Cathode Ray Tube, picture tube) display device was the main display device. However, with the continuous advancement of technology, various display technologies have sprung up. Recently, various image display devices have Thin, light, small, low power consumption, and no radiation hazard are widely used. As people's demand for 2D and 3D increases day by day, the 2D and 3D drivers of image display devices also need to be perfected urgently. [0003] The invention with the patent number CN101888564A in the prior art provides an image display device. In this image display device, one pixel is divided into six sub-pixels, and the first gate line is simultaneously controlled by three thin-film transistors (TFTs). F...
