Abstract
A display apparatus includes a display panel, a light source unit including a plurality of light sources that irradiate the display panel with light, a first control signal generating unit that inverts and forward rectifies a scan signal for scanning of the light source unit, a second control signal generating unit that inverts and backward rectifies an overdrive signal for overcurrent emission of the light source unit and has its output port coupled to an output port of the first control signal generating unit, and an inverter that supplies current to the light source unit based on a control signal output from the output port of the first control signal generating unit and the output port of the second control signal generating unit.
Claims10
A display apparatus comprising:
- a display panel;
- a light source unit comprising a plurality of light sources that irradiate the display panel with light;
- a first control signal generating unit that inverts and forward rectifies a scan signal for scanning of the light source unit;
- a second control signal generating unit that inverts and backward rectifies an overdrive signal for overcurrent emission of the light source unit and has an output port coupled to an output port of the first control signal generating unit;
- and
- an inverter that supplies current to the light source unit based on a control signal output from the output port of the first control signal generating unit and the output port of the second control signal generating unit.
A method of controlling a display, the method comprising:
- inverting and forward rectifying a scan signal for scanning of a light source unit, to generate a first control signal;
- inverting and backward rectifying an overdrive signal for overcurrent emission of the light source unit, to generate a second control signal;
- supplying current to the light source unit based on the first control signal and the second control signal, to generate light;
- and
- irradiating a display panel with the generated light.
