Abstract
A light source module includes a LED array, a switch and a control part. The LED array includes a plurality of LED rows and a bridge light emitting part connecting the LED rows with each other. Each of the LED rows has a first direction light emitting part and a second direction light emitting part which are alternately disposed with each other. The switch adjusts an intensity of a current applied to the LED array. The control part determines an output status of the LED array and provides a control signal to the switch.
Claims19
A light source module comprising:
- a light emitting diode (“LED”) array including a plurality of LED rows and a bridge light emitting part connecting the LED rows with each other, each of the LED rows having a first direction light emitting part and a second direction light emitting part which are alternately disposed with each other;
- a switch configured to adjust a level of intensity of a current input into the LED array;
- and
- a control part configured to determine an output status of the LED array and to provide a control signal to the switch, and
- wherein an output terminal and a control terminal of the switch are connected to the control part, and an input terminal of the switch is connected to an output terminal of the LED array.
A method of driving a light source module, the method comprising:
- driving an LED array including a plurality of LED rows and a bridge light emitting part connecting the LED rows with each other, each of the LED rows having a first direction light emitting part and a second direction light emitting part which are alternately disposed with each other;
- adjusting an intensity of a current by a switch to be input into the LED array;
- inputting the current having the adjusted intensity into the LED array;
- and
- determining an output status of the LED array by a control part and outputting a control signal to the switch to control the output of the LED array;
- wherein an output terminal and a control terminal of the switch are connected to the control part, and an input terminal of the switch is connected to an output terminal of the LED array.
A display apparatus comprising:
- a display panel including a plurality of pixels;
- a light source module including:
- an LED array including a plurality of LED rows and a bridge light emitting part connecting the LED rows with each other, each of the LED rows having a first direction light emitting part and a second direction light emitting part which are alternately disposed with each other;
- a switch configured to adjust a level of intensity of a current input into the LED array;
- and
- a control part configured to determine an output status of the LED array and to provide a control signal to the switch, and
- wherein an output terminal and a control terminal of the switch are connected to the control part, and an input terminal of the switch is connected to an output terminal of the LED array.
