An optical transmission system includes an optical emitting device and a plurality of optical receiving devices. The optical receiving devices are optically connected in series and one of the optical receiving devices is optically connected to the optical emitting device. Each of the optical receiving devices includes a control module, an optical receiving terminal, and an optical fiber amplifier. The optical emitting device emits out first optical signals or second optical signals. The control module transmits the first optical signals to the optical receiving terminal or transmits the second optical signals to the optical fiber amplifier. The optical fiber amplifier amplifies the second optical signals and sends the amplified second optical signals to the next optical receiving device.

A flat panel display includes a data interface, a scaler control circuit, and a pulse generator configured to provide an independent pulse signal to the scaler control circuit. The data interface is configured to receive an image signal including a vertical synchronization pulse signal and a horizontal synchronization pulse signal. The scaler control circuit is configured to determine a vertical resolution of the image signal by counting a number of pulses of the independent pulse signal respectively between two adjacent vertical synchronization pulses and between two adjacent horizontal synchronization pulses. A method for detecting a resolution of an image signal received by the flat panel display is also provided.
