Abstract
A system for testing Liquid Crystal Displays (LCDs), includes: a controlling computer, an encoder, an IR transmitter, an IR receiver, and a decoder. The controlling computer is for transmitting a test instruction. The encoder is for receiving the test instruction via a port, and encoding the test instruction into an infrared (IR) signal. The IR transmitter is for transmitting the IR signal. The IR receiver is for receiving the IR signal. The decoder is for decoding the IR signal into a Visual Graphic Array (VGA) signal, and transmitting the VGA signal via a VGA port. A related method for testing LCDs is also provided.
Claims13
A system for testing Liquid Crystal Displays (LCDs), the system comprising:
- a controlling computer for transmitting a test instruction;
- an encoder for receiving the test instruction via a port, and encoding the test instruction into an infrared (IR) signal;
- an IR transmitter for transmitting the IR signal;
- an IR receiver for receiving the IR signal;
- and
- a decoder for decoding the IR signal into a Visual Graphic Array (VGA) signal, and transmitting the VGA signal via a VGA port.
A method for testing Liquid Crystal Displays (LCDs), the method comprising the step of:
- providing a controlling computer to send a test instruction;
- providing an encoder to receive the test instruction via a port, and encode the test instruction into an infrared (IR) signal;
- providing an IR transmitter to transmit the IR signal;
- providing an IR receiver to receive the IR signal;
- providing a decoder to decode the IR signal into a Visual Graphic Array (VGA) signal, and transmitting the VGA signal via a VGA port;
- and
- performing a test item on one of the LCDs to be tested corresponding to the VGA signal.
A method for testing display devices, comprising the step of:
- presetting test instructions for testing display devices in a controlling computer;
- presetting testing items corresponding to said test instructions in a testing terminal capable of performing selective ones of said testing items on said display devices;
- and
- transmitting user-selected test instructions from said controlling computer to said testing terminal by means of wireless transmission so as to initiate performing said selective ones of said testing items on said display devices according to said user-selected test instructions.
