Liquid crystal display device

摘要

When a first source bus line (SA) or a second source bus line (SB) which is associated with a pixel of one column is electrically connected with a spare wire (AL1), a control circuit (15B) of a liquid crystal display device (100B) according to an embodiment of the present invention is capable of controlling the amplitudes of the oscillation of a first display signal voltage and a second display signal voltage output to the first source bus line (SA) and the second source bus line (SB) so as to be smaller than that achieved when the first source bus line (SA) or the second source bus line (SB) is not electrically connected with the spare wire (AL1).

主权项

1. A liquid crystal display device, comprising:
a plurality of pixels arranged in a matrix of rows and columns, each of the plurality of pixels including a first sub-pixel and a second sub-pixel; a first TFT and a second TFT which are associated with each of the plurality of pixels; a first source bus line connected to the first sub-pixel via the first TFT and a second source bus line connected to the second sub-pixel via the second TFT; a spare wire which is electrically connectable with the first source bus line and/or the second source bus line; and a control circuit configured to receive an input display signal that is indicative of grayscale levels which are to be exhibited by the plurality of pixels, generate a first display signal voltage and a second display signal voltage which are to be supplied to the first sub-pixel and the second sub-pixel of each of the plurality of pixels, and output the generated first and second display signal voltages to the first source bus line and the second source bus line, respectively, wherein when the first source bus line or the second source bus line which is associated with a pixel of one column is electrically connected with the spare wire, the control circuit is capable of controlling amplitudes of oscillation of the first display signal voltage and the second display signal voltage output to the first source bus line and the second source bus line associated with the pixel of the one column so as to be smaller than that achieved when the first source bus line or the second source bus line associated with the pixel of the one column is not electrically connected with the spare wire.
