Reset displaying device, reset displaying method and cooking heating equipment

Abstract

The invention provides a reset displaying device, a reset displaying method and cooking heating equipment. The reset displaying device comprises a control module and a display module, wherein the control module is connected to the display module, and is used for sending display state information to the display module according to a preset time interval and receiving state feedback information sent by the display module, the display module is used for displaying the display state information sent by the control module, collecting state feedback information and sending the collected state feedback information to the control module, the control module is also used for judging whether the display module normally works or not according to the receiving state of the state feedback information, and when the judgment result is no, sending a reset signal with the current display state information to the display module so as to enable the display module to be reset according to the reset signal and to be started, and displaying according to the current display state information at the same time. When the display module of the cooking heating equipment has a fault, the reset time of the display module is shortened, and information needed to be currently displayed is fast recovered, so that the use experience of a user is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of display systems, in particular to a display reset device, a display reset method and a cooking heating device. Background technique [0002] At present, many cooking and heating devices, such as electric rice cookers, induction cookers, and electric pressure cookers, use liquid crystal display modules to display information such as working status. The LCD driver module is integrated in the display module, and the LCD driver module and the main control module mainly use IIC (Inter-Integrated Circuit, integrated circuit bus) or other communication methods to realize information transmission, but the LCD module often has a dead screen phenomenon, and After reset, it takes a long time to restore the current screen that needs to be displayed. [0003] For example, when an induction cooker with a TFT (Thin Film Transistor, Thin Film Transistor) liquid crystal screen is working, under the influence of i...

AI Technical Summary

Problems solved by technology

[0003] For example: when an induction cooker with a TFT (Thin Film Transistor, thin film transistor) LCD screen is working, under the influence of external electromagnetic and other interference factors, it is easy to appear dead screen and other phenomena

After the dead screen, it can be displayed normally after automatic (manual) reset, but during the reset process of the TFT screen, it often takes a long time from power-on reset to re-displaying the current display state, and due to this dead screen phenomenon have occurred, therefore, it brings a lot of inconvenience to users and greatly reduces the user experience
