Embodiment Construction

[0061] In order to further illustrate the control circuit, the control method thereof, and the electronic equipment provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0062] As described in the background art, taking an electronic device as an example of a display device, the processor (such as Scalar IC, MCU, etc.) included in the display device cannot normally control the general-purpose input / output ports ( GPIO) to output a normal enable signal, which may easily lead to an abnormal working state of each functional module included in the display device, affecting user experience.

[0063] Based on the existence of the above-mentioned problems, the inventors of the present invention have found through research that the GPIO can be controlled to output normal signals at the moment of power-on or power-off by separately designing the peripheral circuit, thereby avoiding the abnormal s...

Abstract

The invention discloses a control circuit, a control method of the control circuit, and electronic equipment, relates to the technical field of display, and aims to solve the problem that the user experience is influenced due to the fact that the function of the electronic equipment is abnormal at the moment of on and off. The control circuit comprises a first control sub-circuit, a second controlsub-circuit and a third control sub-circuit; the first control sub-circuit, the second control sub-circuit and the third control sub-circuit work in a matched manner; and therefore, the level of a port to be controlled is the non-effective level at the on and off moment of the electronic equipment, and is the effective level in the working period of the electronic equipment. The control circuit provided by the invention is used in the electronic equipment.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a control circuit, a control method thereof, and electronic equipment. Background technique [0002] With the continuous development of display technology, the application range of display devices is becoming wider and wider. Display devices generally include a display area and a surrounding area around the display area. In addition to the integrated circuit module that realizes the display function in the area, other functional modules can also be set, such as: audio output module, etc.; in actual application, the display device controls the general-purpose input / output port through its included processor to output the corresponding control signal. Therefore, each functional module included in the display device is controlled to realize corresponding functions. [0003] However, since the processor is not in a normal working state when the display device is turned on or off, i...
