The disclosure relates to an OLED display device and a control method thereof, and relates to the field of display technology. The display device includes: a switch unit, electrically connected to the standby voltage terminal of the power board and the standby voltage terminal of the main chip, and used to control the connection and disconnection of the standby voltage terminal of the power board and the standby voltage terminal of the main chip; The switch unit is electrically connected, and is used to control the conduction and cut-off of the switch unit in response to the AC detection signal output by the power board and the DC detection signal output by the main chip, wherein the AC detection signal is used to detect whether an AC power failure or AC is received. The power-on signal and the DC detection signal are used to detect whether a DC power-off or DC power-on signal is received. The present disclosure can quickly cut off the standby voltage when the AC power is cut off, so that the display device can be started normally when the AC power is turned on, and can ensure normal standby when the DC power is cut off.
Description
technical field [0001] The present disclosure relates to the field of display technology, in particular, to an OLED display device and a method for controlling the OLED display device. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology, as a new type of display technology, has gradually received more attention. [0003] Figure 1A A schematic diagram of an AC power-on sequence of an OLED display device in a technical solution is shown. refer to Figure 1A As shown, T0 represents the time interval from the rise of the standby power supply signal 3.3VS to the rise of the reset signal (150μS<T0<1S), refer to figure 2 As shown, the level of the reset signal is the level at the node R. When the standby power supply signal 3.3VS becomes high level, the level at the node R rises with the charging of the capacitor C21. Therefore, the standby power supply signal 3.3VS After VS becomes high level...
