A self-key detection method for display products

Abstract

The present invention discloses a self-key detection method for display products. A communication protocol is established between a PC and a product. The product-side MCU reads the key voltage value of a mechanical key or reads the register value of a touch key to obtain the corresponding key value. Based on the collected key value, the test is determined to determine whether the test passes and the corresponding key test result is displayed. A test tool on the PC reads the test result as pass or fail. This method facilitates rapid and efficient production key detection for electronic products such as displays with buttons.
