Abstract

The invention relates to an OLED display device and a control method thereof, and relates to the technical field of display. The display device comprises a switch unit which is electrically connectedwith a standby voltage end of a power panel and a standby voltage end of a main chip and is used for controlling connection and disconnection of the standby voltage end of the power panel and the standby voltage end of the main chip; a control unit, electrically connected with the switch unit, and used for responding to an alternating-current detection signal output by the power panel and a direct-current detection signal output by the main chip to control the switch-on and switch-off of the switch unit. The AC detection signal is used for detecting whether an AC power-off or AC power-on signal is received, and the DC detection signal is used for detecting whether a DC power-off or DC power-on signal is received. According to the invention, the standby voltage can be quickly cut off duringAC power failure, so that the display device can be normally started during AC power-on, and normal standby can be ensured during DC power failure.

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...
