  • Electronic device and voice recognition method thereof
    Patent number: 11984119
    Abstract: An electronic device and a voice recognition method thereof are provided. A voice recognition method of an electronic device includes receiving trigger voice, storing a characteristic of the trigger voice for voice verification by analyzing the trigger voice. When a user issues a voice command, determining whether the user voice command comprises the characteristic belonging to the trigger voice, and performing function of the electronic device corresponding to the user voice command based on the determination. Accordingly, users may easily use the voice recognition function of the electronic device.

  • Method for manufacturing liquid crystal display device
    Patent number: 6977697
    Abstract: A method for manufacturing an LCD device is disclosed, which has a reflective electrode having protrusions formed by simplified manufacturing process steps, thereby improving reflectivity. The method includes: forming a first insulating layer on a substrate; forming a photoresist layer on the first insulating layer, wherein the photoresist layer has a plurality of rounded protrusions and rounded valleys; forming a plurality of rounded protrusions and rounded valleys on the first insulating layer by etching the first insulating layer and the photoresist layer; and forming a reflective electrode on the first insulating layer.
