Patent ID: 8547322

Claim:
A method for driving a display device comprising: a liquid crystal panel comprising: a first substrate; a pixel matrix circuit over the first substrate, the pixel matrix circuit comprising: a thin film transistor over the first substrate; an insulating film over the thin film transistor; and a pixel electrode over the insulating film; a liquid crystal over the pixel matrix circuit; and an LED light source comprising a red LED array, a green LED array, a blue LED array, and a resin covering the red LED array, the green LED array, and the blue LED array, wherein the red LED array comprises a plurality of red LED chips which are one-dimensionally arranged, wherein the green LED array comprises a plurality of green LED chips which are one-dimensionally arranged, wherein the blue LED array comprises a plurality of blue LED chips which are one-dimensionally arranged, and wherein the red LED array, the green LED array, and the blue LED array are provided in parallel to one another; the method comprising the steps of: displaying a red image on the liquid crystal panel, comprising the steps of: writing red image data into the pixel electrode in the pixel matrix circuit in the liquid crystal panel; and controlling the red LED array, wherein a red light passes through the liquid crystal when the red LED array is turned on; displaying a green image on the liquid crystal panel, comprising the steps of: writing green image data into the pixel electrode in the pixel matrix circuit in the liquid crystal panel; and controlling the green LED array, wherein a green light passes through the liquid crystal when the green LED array is turned on; and displaying a blue image on the liquid crystal panel, comprising the steps of: writing blue image data into the pixel electrode in the pixel matrix circuit in the liquid crystal panel; and controlling the blue LED array, wherein a blue light passes through the liquid crystal when the blue LED array is turned on, wherein the step of controlling the red LED array is in synchronism with the step of writing the red image data, wherein the step of controlling the green LED array is in synchronism with the step of writing the green image data, wherein the step of controlling the blue LED array is in synchronism with the step of writing the blue image data, and wherein the step of displaying the red image, the step of displaying the green image and the step of displaying the blue image are successive.
