Patent ID: 7911579

Claim:
A flat display apparatus comprising: a panel having a plurality of substrates and P photo spacers, wherein said P photo spacers are disposed in between said substrates providing a fixed distance between said substrates, wherein said P photo spacers having two opposite sides, and both said two opposite sides directly contact said substrates, wherein said P photo spacers having an arrangement that an area unit composed of N×N sub-area units with multiple columns and multiple rows, wherein N 3 3; and in an arrangement mode, providing said P photo spacers uniformly distributed on said allocated area unit of the N×N sub-area units, wherein on substantially the entire allocated area unit composed of N×N sub-area units there is a single photo spacer in each column, and there is a single photo spacer in each row; a displacement parameter x to be x column sub-area unit; a first location, predetermining located in the first column, first row of the area unit; a second location, displacing the first location to second row to be a start location, displacing the x column sub-area unit horizontally from the start location at same row to be the second location; and an n location, displacing an n−1 location vertically to an n row to be a start location, displacing the x column sub-area unit horizontally from the start location at the same row to be an n location, wherein, if the x column sub-area unit is greater than remaining columns of the row, continuing said calculation from the first column of the row, wherein the area unit repeatedly arranges at four quadrant locations and provides a selection unit of equaling the area unit, wherein the selection unit is selected from the repeated four quadrant locations in order to be the arrangement mode of the photo spacers.
