Problems solved by technology

The production process of PDP display is complex and costly, the driving circuit is difficult, and the power consumption is large
It is almost impossible for a pure LED display to produce a high-resolution full-color display for home use, mainly because of its large size and high cost. At present, the optical fiber display in the market usually directly corresponds to other display screens, so it is difficult to reflect its quality. Advantages, only play a role in magnification, but not good for image quality improvement

Embodiment Construction

[0035] Fig. 1 is a schematic diagram of the overall configuration of the LED fiber optic display of the present invention with a rotating drum. As shown in the figure, the LED fiber optic display of the present invention is generally composed of a rotating drum 1, an optical fiber 4 and an optical fiber display screen 2, wherein the input end of the optical fiber 4 Corresponding to the rotating drum 1 , the output end of the optical fiber 4 is connected to the optical fiber display screen 2 , and the optical fiber display screen 2 receives the light emitted by the LED on the rotating drum 1 through the optical fiber 4 .

[0036] Fig. 1a is a partially enlarged view of the optical fiber display screen 2 shown in Fig. 1. The optical fiber display screen 2 is composed of an array of 1280*768 optical fibers, of which 1280 are arranged along the horizontal direction and 768 are arranged along the vertical direction.

[0037] Referring to Fig. 1b, Figs. 3 to 7, the structure of the d...

Abstract

The LED optical fiber display includes fiber display screen; fiber system with fibers connected to the fiber display screen in the output; LED scanning and imaging system with LED devices to emit light signals to the inputs of the fibers; control system to convert the received light signals into exciting signals for LED's to emit light; and driving system to drive the LED scanning and imaging system to rotate. Under the driving of the driving system, the LED scanning and imaging system moves relatively to the inputs of the fibers in the frequency and speed to generate normal pixels and emits light signals to the inputs of the fibers, so that corresponding LED bright dots are displayed on the fiber display screen. The fiber outputs are arranged regularly to show complete planar image in the fiber display screen.

Description

technical field [0001] The invention relates to an LED optical fiber display which uses LED as a signal light source and makes the photoelectric signal of the LED smoothly pass through the scanned optical fiber to transmit the image signal. Background technique [0002] Currently popular displays on the market include LCD displays, PDP displays, TFT-LCD displays, LED displays, and fiber optic displays. These displays have their own advantages, but they also have their own problems. For example, LCD displays and TFT-LCD displays do not emit light by themselves, and must rely on external light sources to display. Moreover, the light transmittance of TFT-LCD is very low, only 6%-10%. Therefore, the light loss is very large, and the cost is high if a large-area TV display is produced. The production process of the PDP display is complex and costly, the driving circuit is difficult, and the power consumption is large. It is almost impossible for a pure LED display to produce a...
