Title:
DRIVE CIRCUIT OF BACKLIGHT MODULE AND DISPLAY DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/155736
Kind Code:
A1
Abstract:
A drive circuit of a backlight module and a display device using same. The drive circuit comprises a transistor (T1, T2), connected to multiple light-emitting diodes (120); a constant current circuit (151), connected to the transistor (T1, T2); a power resistor (R2, R4), connected in parallel with the transistor (T1, T2); and a power switch (Q1, Q2), connected between the transistor (T1, T2) and the power resistor (R2, R4). A switch signal is transmitted to the power switch (Q1, Q2). The level of the switch signal in a three-dimensional image mode is higher than the level of the switch signal in a two-dimensional image mode. The drive circuit is applicable to a display device, and can increase the brightness of the backlight module in the three-dimensional image mode.
