Embodiment Construction

[0019] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. figure 1 It is a plan view showing the first embodiment of the full-color LED display panel of the present invention, figure 2 yes figure 1 The enlarged cross-sectional view of the main part. This full-color LED display panel is a display panel that displays video in color, and is configured to include an LED array substrate 1 and a fluorescent light-emitting layer substrate 2 .

[0020] Such as figure 1 As shown, the above-mentioned LED array substrate 1 is equipped with a plurality of LEDs 3 arranged in a matrix, and is formed by disposing an LED array including the above-mentioned plurality of LEDs 3 on a wiring substrate 4. An external drive circuit is supplied to each LED 3 to individually drive each LED 3 on and off to turn on and off the wiring.

[0021] The above-mentioned LED 3 emits light in the ultraviolet to blue band, and is made of gallium nitride (...

Abstract

The present invention is provided with: an LED array substrate (1) which is formed by disposing, on a substrate, a matrix of a plurality of LEDs (3) capable of radiating light in a wavelength range from ultraviolet to blue; a plurality of fluorescence emitting layers (5) which are juxtaposed side by side on the LEDs (3) so as to correspond to the three primary colors of light and which are excitedby excitation light radiated from said LEDs (3) so as to have the respective wavelengths thereof converted into fluorescence of the corresponding colors; and an excitation light cut-off layer (8) which is disposed so as to cover the fluorescence emitting layers (5) in order to cut off the excitation light.

Description

technical field [0001] The invention relates to a full-color LED display panel, in particular to a full-color LED display panel which is easy to manufacture and has excellent color reproduction. Background technique [0002] A conventional full-color LED display panel is capable of color display by arranging red, green, and blue LEDs as a set in a dot matrix (for example, refer to Patent Document 1). [0003] In addition, another full-color LED display panel has: an array of micro-LED devices, which emit blue (for example, 450nm-495nm) or dark blue (for example, 420nm-450nm) light; On the array of the micro LED devices, the blue or deep blue light emitted from the micro LED devices is absorbed, and the emission wavelength of the light is converted into various lights of red, green and blue respectively (for example, refer to Patent Document 2 ). [0004] prior art literature [0005] patent documents [0006] Patent Document 1: JP-A-2012-145725 [0007] Patent Docume...
