Method and apparatus for display sign
First Claim
1. A matrix display apparatus comprising:
- a. a mounting structure providing a front display area;
b. a plurality of display elements positioned at respective spaced locations across said display area, each of said display elements having a display region at a respective display location in said display area;
c. each of said display elements comprising a color responsive pixel member having a set of color responsive pixel sections, each of which has a color character differing from the color character of other color responsive pixel sections of said set;
d. actuating apparatus to selectively move the pixel members to position selected ones of said pixel sections at operative locations in their display elements to provide pixel images at the display regions where a multi-color image can be displayed by displaying various pixel images of different color character in an appropriate pattern corresponding to the image to be displayed;
e. said color responsive pixel members each comprising a pixel strip with said pixel sections being positioned at spaced locations along said strip, and said actuating apparatus moves said pixel strip through increments of travel to position selected ones of said pixel sections at the display area.

Abstract
A matrix display sign and system where the displayed image or message can readily be changed. There is an array of pixel units arranged in rows and columns, and each of these pixel units can be selectively activated to display various selected colors. In a preferred embodiment, each pixel unit is capable of displaying any of a blue, green, red, white or black color. Each pixel unit has an elongate strip member having pixel sections, each having a different color characteristic. The pixel strip is moved in increments so that various pixel sections can be moved into a display region where either reflective light or transflective light illuminates the pixel section. A solenoid driver is activated to move in stepped increments to move the pixel strip to selected positions at the display region.

11. A method of providing a display apparatus comprising:
-
a. providing a display apparatus comprising;
i. mounting structure providing a front display area;
ii. a plurality of display elements positioned at respective spaced locations across said display area, each of said display elements having a display region at a respective display location in said display area;
iii. each of said display elements comprising a color responsive pixel member having a set of color responsive pixel sections, each of which has a color character differing from the color character of other color responsive pixel sections of said set;
b. selectively moving the pixel members to position selected ones of said pixel sections at operative locations in their display elements to provide pixel images at their respective display regions where a multi-color image can be displayed by displaying various pixel sections of different color character in an appropriate pattern corresponding to the image to be displayed;
c. said method further comprising positioning said color responsive pixel member on a pixel strip with said pixel sections being positioned at spaced locations along said strip, said method further comprising moving said pixel strip through increments of travel to position selected ones of said pixel elements at the display area. - View Dependent Claims (12, 13, 14, 15, 16)
