Display device

Abstract

The invention provides a display device. The display device comprises a bus group, a resistor unit and an over-current protection module, wherein one end of a first resistor of the resistor unit is connected to a first low-frequency control signal, and the other end of the first resistor is electrically connected with one end of a corresponding first low-frequency control signal bus, one end of asecond resistor is connected with a second low-frequency control signal, and the other end of the second resistor is electrically connected with one end of a corresponding second low-frequency controlsignal bus, and the sum of the resistances of the first resistor and the second resistor of each resistor unit is larger than the ratio of the difference between the high potential and the low potential of the first low-frequency control signal to the preset protection current. In this way, no matter at which position the first low-frequency control signal bus and the second low-frequency controlsignal bus are short-circuited, the current of the first low-frequency control signal bus and the current of the second low-frequency control signal bus are both smaller than the protection current,so that the protection current value is set to be higher on the premise that the temperature of the display device is not influenced.

AI Technical Summary

Problems solved by technology

For example, in the experiment, when the short-circuit current of the first low-frequency control signal bus and the second low-frequency control signal line is 45mA, the temperature will reach 45°C, and the temperature will reach 45°C only when the short-circuit current of the two clock signal bus lines reaches 60mA. If the preset maximum temperature is 45°C, if 60mA is used as the protection current at this time, when the first low-frequency control signal bus and the second low-frequency control signal bus are short-circuited, the first low-frequency control signal bus and the second low-frequency control signal bus are short-circuited. The over-current protection will only be triggered when the current is 60mA, but at this time, the heat generated by the short circuit between the first low-frequency control signal bus and the second low-frequency control signal bus makes the temperature of the display device already exceed 45°C, which has a great impact on the product, but If the protection current is set to 45mA, it may lead to false triggering of over-current protection
