Abstract
A backplane design for delivering image data in an efficient manner to a memory cell forming a part of a pixel driver comprises a word line design and a column data register release signal delivery design that are speed matched and a complementary bit line delivery design that is speed matched to a row decoder signal circuit operative to pull a word line driver to a state to enable the memory circuits of that row to receive data from the column drivers for each column. The speed matching is effective over a range of operating temperatures because the circuit designs are substantially identical.
Claims17
An apparatus, comprising:
- a pixel driver of interest within a pixel driver array;
- a wordline path including a row select path and a wordline, the row select path including a plurality of row drivers and a first plurality of dummy pixel drivers;
- and
- a bitline path including a data load trigger path and a bitline, the wordline and the bitline intersecting at the pixel driver of interest within the pixel driver array, the data load trigger path includes a column driver and a second plurality of dummy pixel drivers.
