Display device

A display device comprising:

• a first display panel having pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes;
• a second display panel having pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes;
• a first flexible substrate connected to the first display panel;
• a second flexible substrate connected to the second display panel and to the first flexible substrate;
• and
• a driver integrated circuit that outputs driving signals shared commonly by and supplied to the signal and scanning electrodes of the first and second display panels;
• wherein the first display panel is a color display panel and the pixels of the first display panel comprise multi-color pixels;
• wherein the pixels of the second display panel comprise single-color pixels;
• wherein the number of the signal electrodes of the second display panel are fewer in number than the signal electrodes of the first display panel;
• and
• wherein the driving signals output from the driver integrated circuit are supplied to the signal electrodes of the second display panel in only one color from among the colors of the multi-color pixels of the first display panel.

A display device, comprising:

• a first display panel having pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes;
• a second display panel having pixels formed of two groups of electrodes corresponding to signal electrodes and scanning electrodes, the electrodes in at least one of the two groups of electrodes of the second display panel being connected to some but not all of respective ones of the electrodes in the corresponding group of electrodes of the first display panel;
• and
• a driver integrated circuit that outputs driving signals shared commonly by and supplied to the signal and scanning electrodes of the first and second display panels;
• wherein the pixels of the first display panel comprise multi-color pixels and the pixels of the second display panel comprise single-color pixels;
• wherein the electrodes in the least one of the two groups of electrodes of the second display panel comprise the signal electrodes;
• and
• wherein the driving signals output from the driver integrated circuit are supplied to the signal electrodes of the second display panel in only one color from among the colors of the multi-color pixels of the first display panel.

A display device comprising:

• a first display panel having pixels formed, in part, of a number of first electrodes;
• a second display panel having pixels formed, in part, of second electrodes that are fewer in number than the number of the first electrodes;
• and
• a driver integrated circuit that outputs driving signals shared commonly by and supplied to the first and second electrodes;
• wherein the pixels of the first display panel comprise multi-color pixels and the pixels of the second display panel comprise single-color pixels;
• and
• wherein the driving signals are supplied to the second electrodes in only one color from among the colors of the multi-color pixels of the first display panel.
