Abstract:
1. A control circuit for a display device comprising: a shift register circuit which includes at least one transistor and outputs a gate signal in response to at least one voltage signal; a temperature information acquisition unit configured to acquire temperature information at the control circuit for a display device; a voltage switching unit configured to switch a voltage of the at least one voltage signal based on the acquired temperature information; a first threshold value storing unit configured to store a first threshold temperature, and a second threshold value storing unit configured to store a second threshold temperature which is different from the first threshold temperature; wherein the voltage switching unit switches a temperature dropping time voltage of the at least one voltage signal when the acquired temperature information indicates that a temperature becomes a temperature lower than the first threshold temperature from a temperature higher than the first threshold temperature, wherein the voltage switching unit switches a temperature rising time voltage of the at least one voltage signal when the acquired temperature information indicates that a temperature becomes a temperature higher than the second threshold temperature from a temperature lower than the second threshold temperature, wherein the voltage switching unit does not switch the temperature rising time voltage when the acquired temperature information indicates that a temperature becomes a temperature higher than the first threshold temperature from a temperature lower than the first threshold temperature, and wherein the voltage switching unit does not switch the temperature dropping time voltage when the acquired temperature information indicates that a temperature becomes a temperature lower than the second threshold temperature from a temperature higher than the second threshold temperature.
