Embodiment Construction

[0026] see figure 1 , is a schematic cross-sectional structure diagram of a preferred embodiment of the LED display device of the present invention. The LED display device 10 includes: a lower substrate 11 , a plurality of unpackaged LED light-emitting chips 13 , an intermediate layer 15 and an upper substrate 17 .

[0027] The lower substrate 11 is a carrier substrate and includes an upper surface 111 and a lower surface 113 opposite to each other. The upper surface 111 of the lower substrate 11 is a plane and a wiring area is provided on the upper surface 111. The wiring area is provided with wiring to form a plurality of LED light-emitting chips 13 for binding and driving the LED light-emitting chips 13. An electrical path, so that the external control circuit can transmit electrical signals through the electrical path to control the light-emitting state of the LED light-emitting chip 13 connected to the electrical path. Each LED light-emitting chip 13 is electrically con...

Abstract

The invention relates an LED display device and a manufacturing method thereof. The LED display device comprises a lower substrate, wherein the lower substrate is provided with wirings to form multiple electricity accesses. The LED display device further comprises a plurality of non-packaged LED light-emitting wafers, an interlayer and an upper substrate, each LED light-emitting wafer is bound to the lower substrate through the corresponding electricity access and electrically connected with an external control circuit, the non-packaged LED light-emitting wafers form a light-emitting layer of the LED display device, and the interlayer covers the lower substrate with the LED light-emitting wafers, is used for combining the lower substrate and the upper substrate, and carries out fluorescence processing on light rays emitted by the LED light-emitting wafers to enable the light rays emitted from the LED light-emitting wafers to be converted into white light to be provided for the upper substrate.

Description

technical field [0001] The invention relates to an LED display device and a manufacturing method of the LED display device. Background technique [0002] The traditional LED screen is to arrange multiple LED lights on a substrate according to certain rules to form a light-emitting matrix. Each LED light is composed of LED light-emitting chip and epoxy resin material shell package. Therefore, for LED screens that directly use independent LED lamps to form a light-emitting array, since each LED lamp has a housing package, the packaging structure will occupy a certain display area, resulting in low resolution of the traditional LED screen. Contents of the invention [0003] In order to solve the technical problem of low resolution of LED screens in the prior art, it is necessary to improve an LED display device with high resolution. [0004] Further, a method for manufacturing the LED display device is provided. [0005] An LED display device, the LED display device includ...
