THIN-FILM TRANSISTOR LIQUID-CRYSTAL DISPLAY WITH VARIABLE FRAME FREQUENCY

摘要

An active matrix includes an array of pixels individually addressable over a first frame-frequency range and over a second, higher frame-frequency range. The active matrix also includes, for each pixel of the array, a charging circuit through which that pixel is addressed. Each charging circuit includes an adjustable storage capacitance and is configured such that the storage capacitance is maintained at a first level over the first frame-frequency range, and at a second, lower level over the second frame-frequency range.

1. An active-matrix display comprising:
an array of pixels; drive componentry to individually address each pixel of the array at a variable frame frequency; for each pixel of the array, a charging circuit through which that pixel is addressed, the charging circuit including an adjustable storage capacitance; and capacitance-control componentry including a capacitance-control transistor having a gate and a source, the gate and the source coupled to a common-voltage line, the capacitance-control componentry configured to maintain the storage capacitance of each charging circuit at a first level over a first frame-frequency range, and at a second, lower level over a second, higher frame-frequency range.
