摘要： An array of light-emitting elements is switched on and off to produce a graded-intensity image on a photosensitive medium. Each light-emitting element is controlled by M-bit data representing the intensity of one image pixel, where M is a fixed integer greater than one. M strobe signals are generated for non-overlapping time intervals of different lengths, to strobe the M data bits for each light-emitting element. When strobed, each data bit switches its corresponding light-emitting element on or off. Image intensity depends on the total amount of time for which each light-emitting element is switched on.

摘要： A light-emitting-diode array is formed on a substrate having an upper layer of a semiconducting material and a lower layer of an insulating or semi-insulating material. The upper layer is divided into blocks by isolation channels that cut completely through the upper layer. The light-emitting diodes, which are formed by selective diffusion of an impurity into the upper layer, are arranged in a single row, with at least two light-emitting diodes in each block of the upper layer. Each block has a block electrode that drives the light-emitting diodes in the block. The row of light-emitting diodes is paralleled by a number of shared lines which cross the isolation channels. Each shared line is coupled to a plurality of light-emitting diodes in different blocks.

摘要： An array of LEDs is controlled by a control circuit so as to emit light in a write mode and sense light in a read mode. In the read mode, each LED is alternately charged for a first interval, then allowed to discharge by flow of photocurrent for a second interval. At the end of the second interval, just before charging of the LED begins again, the anode voltage of the LED is read by coupling the anode of the LED to an output terminal for a third interval. The third interval of each LED may coincide with the first interval of the preceding LED in tile array, so that each LED is read while the preceding LED is being charged.
