Embodiment 1

[0041] Preferred Embodiment 1: The liquid crystal display includes a display screen provided with pixel modules, a data drive unit and a scan drive unit connected to the display screen, and a data chip-on-chip device connected to the scan drive unit. The data-on-chip thin film device supports the function of turning on two rows of pixel modules at the same time, and realizes a liquid crystal display refresh method that simultaneously applies turn-on voltage to the two rows of pixel modules.

[0042] Each row of pixel modules is connected to a scanning driving line, and the scanning driving line is connected to a scanning driving unit, and the scanning driving unit applies voltage to the scanning driving line under the control of the data chip-on-chip device.

[0043] The scanning driving unit simultaneously turns on the i-th row and the i+1-th row through the scanning driving line, and the timing control system transmits the grayscale data of the i-th row and the i+1-th row to ...

Embodiment 3

[0053] Preferred Embodiment 3: The liquid crystal display includes a display screen provided with pixel modules, a data drive unit and a scan drive unit connected to the display screen, and a data chip-on-chip device connected to the scan drive unit. The data-on-chip thin film device supports the function of turning on two rows of pixel modules at the same time, and realizes a liquid crystal display refresh method that simultaneously applies turn-on voltage to the two rows of pixel modules. A switching switch is provided in the data chip-on-chip device, and the switching switch sets the scanning driving unit to a 2D mode or a 3D mode.

[0054] Each row of pixel modules is connected to a scanning driving line, and the scanning driving line is connected to a scanning driving unit, and the scanning driving unit applies voltage to the scanning driving line under the control of the data chip-on-chip device.

[0055] The scanning driving unit simultaneously turns on the i-th row and...

Abstract

The invention discloses a refreshing method of a liquid crystal display. A start voltage is provided for at least two lines of pixel modules simultaneously, and liquid crystal units in the pixel modules are controlled to be conducted by the same data driving line. The invention discloses the liquid crystal display, at least comprising a display screen, a data driving unit, a scan driving unit and a data flip-chip thin-film device, wherein the display screen is provided with the pixel modules; the data driving unit and the scan driving unit are connected with the display screen; and the data flip-chip thin-film device is connected with the scan driving unit, and supports the function of simultaneously starting at least two lines of pixel modules. The data flip-chip thin-film device is internally provided with a change-over switch which sets the scan driving unit to be in a 2D (two-dimensional) mode or a 3D (three-dimensional) mode. The invention discloses a liquid crystal television, at least comprising a main board; and the main board is connected to the liquid crystal display and transmits gray-scale data to the scan driving unit in the liquid crystal display.

Description

technical field [0001] The invention relates to a method for refreshing a liquid crystal display, a liquid crystal display and a liquid crystal television. Background technique [0002] A mainstream technology in 3D TV display at present is the shutter type (SG 3D). The realization principle is to sequentially display the left-eye image and the right-eye image in units of frames, and control the left and right eyes to respectively receive the corresponding images in combination with the synchronous switch of the glasses. The main defect of this technology is the problem of crosstalk between the left and right eyes, that is, when the left eyeglass is turned on, the image of the right eye can still be seen, and when the right eyeglass is turned on, the image of the left eye can be seen. [0003] In order to solve the problem of crosstalk, if it is equipped with a 240Hz screen, the common method is to insert black, that is, send the left eye (right eye) image and then send a f...
