Abstract: A self-locking and positioning device for a dental brace, comprising: a brace main body, an elastic piece, and an upper cover. Wherein, on the brace main body is provided with a track and a fixing slot, while on the elastic piece is provided with a positioning piece and a slot. The positioning piece is provided with a barb, while the upper cover slides and fixes into the brace main body through the track. Then, the barb of the positioning piece on the elastic piece will act against a block portion on bottom of said upper cover, to restrict movement of the upper cover, to lock automatically the upper cover into position. The dental brace is simple in construction and easy to assemble, hereby raising production efficiency and yield.

Abstract: An liquid crystal display (LCD) (200) includes an LCD panel (210), a timing control circuit (230), and a backlight module 250. The LCD panel includes a gate drive integrated circuit (IC) (211) and a data drive IC (212) formed thereon for driving the LCD panel. The backlight module includes a backlight (256), an inverter (252), an inverter drive IC (255), a voltage feedback circuit (253), and a phase locked loop (PLL) circuit (254). The timing control circuit receives a synchronized input signal and generates a timing control signal for controlling gate drive IC and the data drive IC according to the synchronized input signal. The PLL circuit receives the synchronized input signal and provides a backlight synchronized signal to the inverter drive IC according to the synchronized input signal. The inverter drive IC controls a frequency of the backlight driving signal according to the backlight synchronized signal.
