Problems solved by technology

[0002] The motherboard and the monitor are connected through a display interface (Display Port, DP) cable. However, when the DP cable does not comply with the Video Electronics Standards Association (Video Electronics Standards Association, VESA) standard, there will be leakage between the monitor and the motherboard. Interfere with normal power sequences and fail to return to the operating system after waking from shutdown or sleep

Abstract

A display is connected to a mainboard to establish a communication connection, the display includes a first interface and a display unit. The motherboard includes a second interface, the second interface is electrically connected to the first interface through a cable, and a leakage protection circuit is arranged between the first interface and the display unit to detect the difference between the first interface and the second interface. Check whether the cable between them meets the VESA standard. The invention also provides an electronic device applying the display. In this way, there is no leakage of electricity between the display and the motherboard, a normal power sequence is ensured, and the risk that the motherboard cannot return to the operating system from shutdown or sleep is avoided.

Description

technical field [0001] The present invention relates to a display and an electronic device using the display. Background technique [0002] The mainboard and the monitor are connected through the Display Port (DP) cable. However, when the DP cable does not conform to the Video Electronics Standards Association (VESA) standard, there will be leakage between the monitor and the mainboard. Interferes with normal power sequences and cannot return to the operating system after waking from shutdown or sleep. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a display and an electronic device using the display. [0004] A display includes a first interface and a display unit, the first interface is connected with a second interface of a main board through a cable, the first interface includes a first idle pin, and the second interface includes a second interface connected to a first power supply Idle pins, the display also includes a leakage pro...
