A method of connecting a mobile terminal and an AP. The mobile terminal has a short-distance wireless communication module and a mobile communication module, and the AP provides a wired / wireless communication interface. The SID and NID of a network with the AP are stored as SID_Bond and NID_Bond at an initial bonding with the AP. It is determined whether a channel established with the AP has been terminated. If the channel is terminated, the SID_Bond and NID_Bond are compared with an SID and NID for the present position. If they are different, the short-distance wireless communication module is transitioned to a low-power mode.

A method and a multimode terminal for minimizing current consumption and simultaneously reducing a handover processing time when a handover occurs between communication networks which provide communication services using different mobile communication technologies. The communication network modems of the multimode terminal are interconnected via a one-to-one communication path, so that a handover target communication network modem is powered on only when handover actually occurs. In this way, by efficiently determining a time point when the handover target communication network modem is powered on, a processing time according to the occurrence of handover can be reduced, and additional current consumption can be minimized.

The invention makes use of the effect that the high parasitic capacitance of the OLED leads to a prolonged drop in luminous intensity after each PWM current pulse during PWM operation. This can advantageously be exploited by the first method, which prevents the luminous intensity from falling to zero during the PWM vacancy in order to avoid the so-called beading effect when the OLED is in motion. By the second method, OLED afterglow is suppressed to achieve better color characteristics without considering the beading effect. For this purpose, the falling edge can be shortened or adjusted in a controlled manner. In a third method, this effect is taken into account when the OLED is switched on in such a way that the rising edge is initially shortened by an excessively high drive current in order to achieve a rapid attainment of the setpoint value of the luminous intensity. These methods are implemented by a drive circuit or control unit according to the invention.
