Abstract
A hair straightening brush with a thin film transistor-liquid crystal display (TFT-LCD) includes a head part and a handheld part. The head part includes a first housing, metal heat-conducting teeth, and an electric heating component. The handheld part includes a second housing, and a main control unit. The electric heating component is electrically connected to the main control unit. A display module is further disposed in the second housing, is provided with a display (TFT-LCD), and is electrically connected to the display. The display module includes a driver circuit and a signal control module, and is configured to generate timing signals for controlling row and column drivers of the display. The driver circuit is configured to: receive the timing signals for controlling the row and column drivers, convert the timing signals into row and column driver analog voltages, output the analog voltages to the display, and control liquid crystal alignment of the display.
