The conductive layer 120 may be tin-doped indium oxide (ITO), zinc oxide (ZnO), or other conductive materials capable of shielding external static electricity, and is not particularly limited.

The temperature detector 131 is used for measuring the temperature of the conductive layer 120, and the control module 133 is used for controlling the driving module 132 to stop driving the display module 110 when the temperature measured by the temperature detector 131 is greater than or equal to a preset temperature value.
The temperature detector 131 may include a detector, such as a temperature probe, for directly measuring the temperature of the conductive layer 120. The temperature sensor 131 may also include an instrument for indirectly measuring the temperature of the conductive layer 120, such as an ammeter 13111, voltmeter 13112, and/or ohmmeter 13114 that may measure the resistance of the conductive layer 120, since the resistance of the conductive layer 120 may change in response to temperature, and the temperature of the conductive layer 120 may be indirectly measured based on the relationship between the resistance of the conductive layer 120 and the temperature of the conductive layer 120.
When the temperature measured by the temperature detector 131 is greater than or equal to the preset temperature value, the control module 133 controls the driving module 132 to stop driving the display module 110. It can be understood that, when the display panel 10 is used, the temperature detector 131 can be used to monitor the temperature of the conductive layer 120 in real time, and the conductive layer 120 is covered on the display module 110, which is equivalent to the temperature detector 131 being used to monitor the temperature of the display module 110, and the control module 133 is used to control the output of the driving module 132, if the temperature measured by the temperature detector 131 is greater than or equal to the preset temperature value, the control module 133 controls the driving module 132 to stop driving the display module 110, so that the situation that the temperature of the display module 110 is higher due to operation and higher than the panel bearing temperature upper limit under the sunlight can be avoided, and irreversible damage of the display module 110 can be avoided.
In some embodiments, the display panel 10 further includes a cooling mechanism for cooling the display module 110, the cooling mechanism is electrically connected to the control module 133, and when the temperature measured by the temperature detector 131 is greater than or equal to a preset temperature value, the control module 133 controls the cooling mechanism to be started so as to cool the display module 110, thereby better avoiding the situation that the display module 110 is higher than the upper limit value of the panel bearing temperature.

It can be appreciated that the resistance scaling module 1312 calculates the temperature of the conductive layer 120 according to the relation between the temperature of the conductive layer 120 and the resistance value of the conductive layer 120, so that the temperature detector 131 can be used to measure the temperature of the conductive layer 120, and when the temperature measured by the temperature detector 131 is greater than or equal to the preset temperature value, the control module 133 can also control the driving module 132 to stop driving the display module 110, so as to avoid irreversible damage to the display module 110.
In some embodiments, the resistance measurement module 1311 includes an ammeter 13111, a voltmeter 13112, and/or an ohmmeter 13114.
The resistance of the conductive layer 120 may be measured using at least one ammeter 13111 or at least one voltmeter 13112, or the resistance of the conductive layer 120 may be measured using an ohmmeter 13114. Specifically, as shown in fig. 3 and 4, an ohmmeter 13114 is connected in series with the conductive layer 120 and is used to measure the resistance of the conductive layer 120.
