Matrix-addressed systems with row-select circuits comprising a serial shift register
First Claim
1. A matrix-addressed system, comprising:
- a system substrate;
an array of pixels arranged in rows and columns disposed on the system substrate, wherein each pixel in the array of pixels comprises one or more light elements;
a column-control circuit for providing information to the pixels, the column-control circuit comprising a separate column-driver circuit connected to each column of pixels that provides information in common to all of the pixels in the column through a corresponding column line; and
a row-select circuit disposed on the system substrate, the row-select circuit comprising a serial shift register comprising a number of row storage elements equal to or larger than the number of rows in the array of pixels, each row storage element in the shift register having a corresponding row-select line connected to all of the pixels in a row.

Abstract
A matrix-addressed system includes a system substrate and an array of pixels arranged in rows and columns disposed on the system substrate. A column-control circuit provides information to or receives information from the pixels. The column-control circuit includes a separate column-driver circuit connected to each column of pixels that provides information in common to all of the pixels in the column or receives information in common from all of the pixels in the column. A row-select circuit likewise disposed on the system substrate includes a serial shift register having a number of row storage elements equal to or larger than the number of rows in the array of pixels. Each row storage element in the shift register has a row-select line connected to all of the pixels in a row.

20. A method of making a matrix-addressed system, comprising:
-
providing a system substrate; disposing an array of pixels arranged in rows and columns on the system substrate; providing a column-control circuit comprising a separate column-driver circuit connected to each column of pixels in the array of pixels that provides information in common to all of the pixels in the column from all of the pixels in the column through a corresponding column line; disposing a row-select circuit on the system substrate, wherein the row-select circuit comprises a serial shift register comprising a number of row storage elements equal to or larger than a number of rows in the array of pixels, each row storage element in the shift register having a corresponding row-select output connected to all of the pixels in a row; and electrically connecting the pixels to the row-select circuit and to the column-control circuit. - View Dependent Claims (21, 22, 23)
