Abstract
The invention relates to the field of display, in particular to a method for automatically detecting a touch key state and a display device. The method is characterized in that a control chip is provided to be connected with a touch module so as to be used for converting touch key signals sent by the touch module into a signal-noise ratio and sensitivity; and a display module is provided to be connected with the control chip so as to display the signal-noise ratio and the sensitivity. The touch key signals are converted into the sensitivity and the signal-noise ratio to be displayed on a factory menu of the display device through an on-screen display (OSD) display chip of the control chip, so that the operators can visually read data of keys through the factory menu.
