Patent ID: 7463251

Claim:
Display device ( 6 ; 6 ′) comprising: a display ( 2 ) having a plurality of display pixels ( 3 ; 3 ′) with light emitting elements (LED) and at least a first drive element (T 1 ) and a second drive element (T 2 ) for driving said light emitting elements (LED) in accordance with an analogue data signal, representing at least one frame in a range from low to high overall light emission states for said display ( 2 ), and a display controller ( 10 ) having a data input ( 9 ) for said analogue data signal, a sensing unit ( 16 ) adapted to evaluate the overall light emission state of said frame and an output ( 13 ) for generating at least one sparkling signal for one or more display pixels ( 3 ; 3 ′) having a high light emission state ( 18 ) exceeding a sensed low overall light emission state of said frame, wherein said display controller ( 10 ) is arranged to individually control said first drive element (T 1 ) and said second drive element (T 2 ) by said sparkling signal such that said one or more display pixels ( 3 ; 3 ′) having said high light emission state are driven by at least one of said drive elements (T 1 ,T 2 ) in a sparkling light emission state ( 18 ′; 18 ″) exceeding said high light emission state ( 18 ).
