Abstract
Abstract A display (10) has pixels organized into columns (21, 22) and rows (26, 27, 28, 29). The columns (21, 22) are precharged to a reference voltage prior to enabling each of the rows (26, 27, 28, 29). The reference voltage is developed using a reference generator (45) and a buffer (46).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
80 words
A method of controlling a display comprising: organizing a plurality of pixels into a plurality of columns; and precharging the plurality of columns to a reference voltage value prior to enabling a row of the display, which includes forming the reference voltage by stimulating non-visible illumination from a reference field emission emitter, using a buffer to receive a voltage value of an input of the reference field emission emitter, and coupling an output of the buffer to the plurality columns.
Claim 2
Independent Claim
80 words
A method of controlling a display comprising: organizing a plurality of pixels into a plurality of columns; and precharging the plurality of columns to a reference voltage value prior to enabling a row of the display, which includes forming the reference voltage by stimulating non-visible illumination from a reference field emission emitter, using a buffer to receive a voltage value of an input of the reference field emission emitter, and coupling an output of the buffer to the plurality columns.
Claim 3
Independent Claim
93 words
A method of controlling a display comprising: precharging a plurality of columns of the display to a reference voltage value that provides non-visible illumination of the display prior to stimulating visible illumination of the display, wherein precharging the plurality of columns of the display to the reference voltage value includes forming the reference voltage by stimulating non-visible illumination from a reference field emission emitter, using a buffer to receive a voltage value of an input of the reference field emission emitter, and coupling an output of the buffer to the plurality of columns.
Claim 4
Independent Claim
93 words
