Data dependent drive scheme and display
First Claim
1. In a display system, a method for controlling a light source, said method comprising:
- receiving a plurality of data bits, each of said data bits associated with a different pixel of a display;
reading the value of each of said data bits;
determining whether each of said data bits has a value indicative of an off-state; and
generating a disable signal if each of said data bits has a value indicative of said off-state, said disable signal causing said light source to turn off.

Abstract
A method for writing data to a display includes the steps of receiving a plurality of data bits, where each bit is associated with a different pixel of the display, reading the value of each data bit, determining whether each data bits has an off-state value, and generating a disable signal if each data bit has an off-state value. Responsive to a disable signal, the method further includes suspending the transfer of data to the pixels of the display, turning off a light source (e.g., an LED, laser, etc.) for a time period dependent on the significance of at least one of the data bits, and/or forcing each pixel of the display into an off state for a time period dependent on the significance of at least one of the data bits. A display driver circuit for performing the methods of the present invention is also disclosed.

15. A display driver circuit for controlling a light source that illuminates a display, said display driver circuit comprising:
-
an input terminal set operative to receive a plurality of data bits, each of said data bits associated with a different pixel of said display; and detection logic operative to read the value of each of said data bits, determine whether each of said data bits has a value indicative of an off-state, and generate a disable signal if each of said data bits has a value indicative of said off-state; and
whereinsaid disable signal causes said light source to turn off. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A display driver circuit for controlling a light source, said display driver circuit comprising:
-
an input terminal set operative to receive a plurality of data bits, each of said data bits associated with a different pixel of said display; means for reading the value of each of said data bits, means for determining whether each of said data bits has a value indicative of an off-state, and means for selectively turning off said light source based on the values of said plurality of data bits.
