Array of light-emitting elements and emission-altering elements
An array of light emitting elements, formed as regions of a second conductive type in a semiconductor layer of a first conductive type, includes at least one emission-altering element provided for the purpose of altering the amount of light emitted by an adjacent light-emitting element. The emission-altering element may be a trench, an opaque member, or a non-emitting region of the second conductive type. Light-emitting elements in the interior of the array can be made to emit the same amount of light as the light-emitting elements at the ends of the array by placing one emission-altering element between at least every second pair of mutually adjacent light-emitting elements. If the array is divided into blocks, the emission-altering elements can also provide electrical isolation between the blocks.
