Crystal display device with void signal wire and driving method thereof

Abstract

The invention provides a liquid crystal display device with virtual signal wires, and a driving method of the LCD device, in particular to an LED device with the virtual signal wires, and a driving method of the LED device; when an LED panel is turned by 180 DEG for use, the picture can still be displayed normally and a plurality of previous line data signals are not lost. The LED device comprises a plurality of pixels which are arranged into a plurality of line and rows in the form of a matrix array, a plurality of data signal wires, each of which is respectively arranged at the first side of the pixels in each line and electrically connected with each pixel in the corresponding line, a plurality of scanning signal wires, each of which is respectively arranged at the first side of the pixels of each line and is electrically connected with each pixel in the corresponding row, at least one virtual scanning signal wire which is arranged at the external-most side of the matrix array, a data driver which is used for driving a plurality of the data signal wires, and a time sequence controller which is electrically connected with the data driver and the scanning driver and comprises at least one memory; when a data input excitation signal is converted into a high-voltage potential, the time sequence controller sends out a starting pulse signal so as to lead the scanning driver to send a scanning wire signal corresponding to the virtual data signal wire and memorizes an image data into the memory; when the virtual scanning signal wires completes the scanning corresponding to the scanning wire signal, the time sequence controller drives the LED device by the data signal wire.

Description

field of invention [0001] The present invention relates to a liquid crystal display device with virtual signal lines and its driving method, and in particular to a liquid crystal display device with virtual signal lines and its driving method. Normal display without losing the data signal of the first few lines. technical background [0002] see figure 1 , is a schematic plan view of a known liquid crystal display device. Such as figure 1 As shown, the liquid crystal display device 100 includes a liquid crystal display panel 110 defining a non-active display area 120 and an active display area 130 thereon. The active display area 130 has a plurality of pixels 160 arranged in a matrix array, a plurality of scanning signal lines 170 are formed along the rows of the pixels 160 and a plurality of data signal lines 180 are formed along the vertical rows of the pixels 160; The scan signals on the scan signal lines 170 are used to control how the data on the plurality of data s...

Problems solved by technology

When the timing controller (Timing Controller) 190a sends out the start pulse signal STV, the scan driver sends out the first scan line signal SDM1, the second scan line signal SDM2..., the tenth scan line signal SDM10 At this time, the image data DATA is sent out one by one according to each pixel data, but due to dummy scan lines or dummy data lines, the front of the screen will be lost. data signals such as Figure 4b shown
