AI Technical Summary

Technical Problem

In the prior art, the reset implementation of the display device requires the addition of a new control module, resulting in a high cost of reset circuit.

Method used

By connecting the real-time clock module to the counting module, the key module is used to control the on-off of the power access module and the counting module, the real-time clock module sends periodic pulse signals, so that the counting module outputs a reset signal when the accumulated count reaches the set overflow value, realizing the long press and reset function.

Benefits of technology

The cost of reset circuit is reduced, and by adding a relatively low-cost counting module, it can achieve long pressing and pressing the reset button to output reset signals, simplifying the circuit design and improving reliability and accuracy.

Abstract

The embodiment of the utility model discloses a long-press reset circuit, a control module, a board card and display equipment. According to the technical scheme provided by the embodiment of the invention, the real-time clock module is connected into the counting module, the real-time clock module sends the periodic pulse signal to the counting module, and when long-time pressing reset is needed, the key module is used for connecting the power supply access module and the counting module to supply power to the counting module, so that the counting module is powered off. The counting module is used for counting based on the pulse signal and outputting the reset signal to the main control module when the cumulative count reaches the set overflow value, so that the main control module executes the reset operation, and the effect of outputting the reset signal by pressing the reset key for a long time can be achieved by increasing the counting module with relatively low cost. And a control module with relatively high cost does not need to be externally hung, so that the reset implementation cost is reduced.
