A flat fluorescent lamp structure comprising a first substrate, a second substrate, a wall structure, a phosphor layer, and a discharge gas is provided in the present invention. The second substrate is oppositely assembled to the first substrate to form a sealed space. The wall structure is utilized to separate the sealed space into a plurality of illuminating chambers. A tunnel penetrates the wall structure to communicate the illuminating chambers. In addition, the tunnel divides the adjacent illuminating chamber into a first illuminating sub-chamber and a second illuminating sub-chamber connecting with each other. The phosphor layer is formed on inner surfaces of the illuminating chambers. The discharge gas is filled in the illuminating chambers. A ratio of a length and a cross-section area of the tunnel defines a first coefficient, a ratio of a length and a cross-section area of the first illuminating sub-chamber defines a second coefficient, a ratio of a length and a cross-section area of the second illuminating sub-chamber defines a third coefficient, and a ratio of the first coefficient and the second coefficient or the third coefficient is greater than 1/20.

Flat fluorescent lamp and structure of the same

A planar photoluminescent lamp. In one embodiment, the planar photoluminescent lamp includes a plurality of barrier walls defining a plurality of channels, wherein each channel is with an axis and formed with a resistive portion characterized by a width, A, and a first capacitive portion and a second capacitive portion both characterized by a width, A, such that A&#x3e;A. The planar photoluminescent lamp also includes a first electrode and a second electrode. The first electrode and the second electrode are substantially perpendicular to the axis of a channel and extend over the first capacitive portions and the second capacitive portions of the plurality of channels, respectively.

Light source for a flat display

A planar light source is disclosed. The planar light source includes an upper substrate having a central portion and two edge portions and a lower substrate opposite to the upper substrate, wherein a plurality of luminous cavities are formed by and between the upper substrate and the lower substrate. With respect to cross sectional areas, one portion of the luminous cavities corresponding to the central portion of the upper substrate is smaller than the other portion of the luminous cavities corresponding to one of the edge portions of the upper substrate, and thus the lightness produced in the central portion is higher than that in the edge portion.
