Display device and display control device

A display device that includes a display panel capable of displaying an image, a controller that controls the display panel, and drivers located for driving the display panel, the drivers including a driver which is located in a most previous stage and supplies a data signal to a driver located in a subsequent stage based on a data signal from the controller, and a driver which is located in a subsequent and operates based on a data signal from a driver located in a previous stage, the display device comprising:

• a detection unit that supplies a monitoring signal, which indicates whether a data signal is supplied to the driver located in the subsequent stage normally, to the controller;
• and
• a substitution controller that supplies a substitution data signal that substitutes for a data signal supplied to the driver located in the subsequent stage based on a substitution control signal from the controller,
• wherein the controller supplies a substitution control signal that makes the substitution controller supply a substitution data signal when it determines that a data signal is not supplied to the driver located in the subsequent stage normally by using the monitoring signal.

A display device that includes a group of gate lines and a group of source lines that cross each other, and displays an image by driving image pixels provided between gate lines and source lines in accordance with a source signal at a timing of a gate signal, the display device comprising;

• source drivers that are located for driving the group of source lines, and include a source driver located in a most previous stage and supplying a source signal from a controller to a source driver located in a subsequent stage, and a source driver located in at least one subsequent stage and supplying a source signal from a source driver located in a previous stage to a source driver located in a subsequent stage;
• a source signal abnormality detection unit that supplies a source monitoring signal, which indicates whether the source signal is supplied normally, to the controller;
• and
• a substitution source controller that supplies a substitution source signal that substitute for a source signal supplied to the driver located in the subsequent stage based on a substitution control signal from the controller,
• wherein the controller supplies a substitution control signal that makes the substitution source controller supply a substitution source signal when it determines that a source signal is not supplied normally to the driver located in the subsequent stage by using the source monitoring signal.

• gate drivers that are located for driving the group of gate lines, and include a gate driver located in a most previous stage and supplying a start signal, which controls a gate signal from a controller, to a gate driver located in a subsequent stage, and a gate driver located in at least one subsequent stage and supplying a start signal from a gate driver located in a previous stage to a gate driver located in a subsequent stage;
• a start signal abnormality detection unit that supplies a start monitoring signal, which indicates whether the start signal is supplied normally, to the controller;
• and
• a substitution start controller that supplies a substitution start signal that substitutes for a start signal supplied to the driver in the subsequent stage based on a substitution start control signal from the controller,
• wherein the controller supplies a substitution control signal that makes the substitution start controller supply a substitution start signal when it determines that a start signal is not supplied normally to the driver located in the subsequent stage by using the start monitoring signal.
