Display device with temperature sensor

摘要

A display device includes a temperature sensor which is arranged in the inside of a housing, and a control unit which calculates a temperature of a display panel based on an output value of the temperature sensor. The control unit calculates the temperature of the display panel based on a current output value of the temperature sensor and an output value of the temperature sensor received prior to the receiving of the current output value. With such a display device, the temperature of the display panel can be calculated with high accuracy even when a temperature of a device which constitutes a heat source is changed.

主权项

1. A display device comprising:
a display panel; a housing which houses the display panel and a heat source device which is a heat source in the display device when the display panel is driven; a temperature sensor arranged in the inside of the housing; and a control unit which calculates a temperature of the display panel based on an output value of the temperature sensor, wherein the control unit calculates the temperature of the display panel based on a current output value of the temperature sensor and an output value of the temperature sensor received prior to the receiving of the current output value; and wherein the control unit multiplies the current output value of the temperature sensor by a coefficient, multiplies a value acquired from the output value of temperature sensor received prior to the receiving of the current output value by a coefficient, and calculates the temperature of the display panel based on the sum of those multiplied values.
