Subsequently, the controller 180 measures the temperature of the panel 132 of the display element 130 through the temperature measuring unit 160 [S82].

If the temperature of the panel 132 measured by the temperature measuring unit 160 is not within a preset temperature range [S83], the controller 180 is within the preset temperature range. Until then, the drive of the panel 132 is stopped for a predetermined time [S84].

In this case, the preset temperature range may be −40 ° C. to 90 ° C., and the preset time may be a time until the temperature of the current panel 132 falls within the preset temperature range.

As described above, when the temperature of the panel 132 is abnormal due to sunlight, the controller 180 does not drive the panel 132 until the panel 132 becomes a normal temperature, thereby preventing the panel ( 132 can be prevented from being damaged by high temperatures.

9 is a flowchart of a sixth embodiment illustrating a process of protecting a display device from sunlight from heat according to the present invention.

Referring to FIG. 9, when a key signal for driving the display element 130 is input from the user through the input unit 110, the controller 180 drives the display element 130 to provide driving image information to the user. [S91].

Subsequently, the controller 180 measures the temperature of the panel 132 of the display element 130 through the temperature measuring unit 160 [S92].

If the temperature of the panel 132 measured by the temperature measuring unit 160 does not fall within a preset temperature range [S93], when the temperature of the panel 132 falls within the preset temperature range. The display brightness of the panel 132 is lowered to a predetermined level until it is displayed [S94].

At this time, the preset temperature range may be -40 ℃ ~ 90 ℃.

That is, the controller 180 controls the power supply unit 190 to lower the driving current supplied to the light source 131 to a preset level. In this case, the preset level is an amount of light for generating a driving image having a minimum display brightness such that the user can recognize the driving image information.

Then, the display brightness of the panel 132 is lower than in the past, and the amount of light emitted from the light source 131 is also reduced, resulting in the effect of lowering the temperature of the panel 132.

As described above, when the temperature of the panel 132 is abnormal due to sunlight, the controller 180 reduces the amount of light generated by the light source 131 until the panel 132 reaches a normal temperature. By lowering the temperature of 132, the panel 132 can be prevented from being damaged by high temperature.

Meanwhile, when the temperature of the panel 132 measured by the temperature measuring unit 160 is within a preset temperature range, the controller 180 maintains the display brightness of the panel 132 at a default value [S95]. .
