Patent ID: 8013877

Claim:
A method of rapidly generating a gray-level versus brightness curve of a display by obtaining a portion of gray-level values and corresponding brightness values of the display, the method comprising: step A: obtaining n sets of (t j , Y j ) values, wherein: j=1˜n, 4≦n≦30; t j is the jth gray-level value; Y j is a corresponding measured brightness value of the jth gray-level value (t j ) displayed on the display; step B: inputting the n sets of (t j , Y j ) values into at least one mathematical formula, wherein the at least one mathematical formula comprises a first mathematical formula: Y j = L max ( 1 + ⅇ a - f ⁡ ( tj ) ) wherein: L max is the maximum brightness of the gray-level versus brightness curve of the display; a is a variable; e is an exponent; f(t) is a function of t, wherein f(t) comprises a plurality of variables; and step C: inputting all variable values obtained from step B into the first mathematical formula to represent a gray-level versus brightness curve.
