1. An apparatus for outputting optically-input texts, comprising:
a light source array, comprising a plurality of light-emitting diodes that are arranged in an array;
a driver, connected to all the light-emitting diodes in the light array, and configured to detect whether each of the light-emitting diodes has detected a drive optical signal from the outside, and drive the corresponding light-emitting diode to be turned on in response to detecting that the drive optical signal has been detected from the outside;
a processor, connected to the light source array and the driver, and configured to recognize a target pattern formed by all the light-emitting diodes that have been turned on; and
a controller, comprising a display screen, and configured to determine a text matching the target pattern as an output text, and display the output text on the display screen,
wherein the controller feeds back a feedback electrical signal to the driver upon completion of displaying the output text,
wherein the driver, in response to the feedback electrical signal, controls the plurality of light-emitting diodes in the light source array to be turned off, and waits for a next process of optically inputting texts.
