Abstract: A display device includes a driving controller sensing a pattern of first image signals from a source external to the driving controller and outputting a compensation selection signal corresponding to the sensed pattern. A voltage generator generates a driving power voltage in response to the compensation selection signal. The voltage generator includes a power converter generating the driving power voltage in response to a power control signal, a comparator comparing the driving power voltage with a reference voltage to output a feedback signal to a first node, and a compensation circuit including a plurality of compensation units. A selected compensation unit is connected to the first node, and a power control circuit outputs the power control signal in response to the feedback signal. The slew rate of the feedback signal may be controlled by a compensation circuit to remove a ripple component from the driving power voltage.

Abstract: A voltage generation circuit of a display device includes an over-current detection circuit that provides a driving voltage to a voltage terminal and outputs an over-current detection signal. The over-current detection circuit includes a current detector that outputs a detection signal at a first level when a voltage corresponding to an output current flowing through the voltage terminal during a blank period, in which a blank signal is activated, is lower than a first reference level or higher than a second reference level, a glitch remover that outputs a noise detection signal when a time period in which the detection signal is maintained at the first level is longer than a reference maintenance time, and a noise filter that activates the over-current detection signal when the noise detection signal is activated at least twice during a predetermined time period.

Abstract: A cradle according to an embodiment may include a housing to be coupled to display modules having various sizes and a light source driver inside the housing. The light source driver may generate a first driving voltage and a second driving voltage to be provided to a light source of the display module coupled to the housing. When the display module has a first size, the light source driver may supply only the first driving voltage to the display module. When the display module has a second size, larger than the first size, the light source driver outputs both the first and second driving voltages to the display module.
