Embodiment 1

[0041] Such as figure 1 As shown, a display panel 100 includes: a back panel 1 , a light emitting lamp panel 2 , a protective layer 3 , a diffusion plate 4 , a fluorescent film unit 5 and a prism sheet 6 .

[0042] The backboard 1 adopts a plastic iron frame structure, mainly to protect and support the upper structure.

[0043] The light-emitting lamp panel 2 includes a lamp substrate 21 and LED chips 22 , and the LED chips 22 are arranged in the lamp substrate 21 in an array at intervals from each other. Specifically, the LED chip 22 can be connected to the copper wire on the lamp substrate 21 by soldering and energized to emit light. In addition, the protective layer 3 can also be formed by coating a transparent adhesive layer on the light-emitting lamp panel 2, which can well prevent the LED chip 22 from being invaded by water and oxygen.

[0044] The diffusion plate 4 is disposed on the protection layer 3 . The diffusion plate 4 can be bulk diffusion or a membrane struc...

Abstract

The invention relates to a display panel and a display device with the same. Fluorescent film units are arranged on a diffusion plate in an array mode at intervals by corresponding to LED chips. On one hand, the fluorescent film units are arranged in an array mode at intervals, and part of blue light emitted by the LED chips does not pass through the fluorescent film units, so that the yellow difference of part of the light is made up for, the "yellow edge" phenomenon of a partition boundary is improved, the color distortion is avoided, and relatively high color restoration and high-contrast display are achieved; and on the other hand, the fluorescent film units are thinner than an existing fluorescent film, so that the thin type application of the display panel can be better facilitated.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device thereof. Background technique [0002] The display device can convert the data of the computer into various characters, numbers, symbols or intuitive images and display them, and can use keyboard and other input tools to input commands or data into the computer, and add, delete, modify and change the display at any time with the help of the system's hardware and software. content. Display devices are classified into plasma, liquid crystal, light emitting diode, and cathode ray tube according to the display device used. [0003] Mini LED, also known as sub-millimeter light-emitting diode, has ultra-thin, special-shaped, local dimming (i.e. TV backlight area adjustment technology), high contrast, narrow frame, and can realize HDR (English full name: high-dynamic range, high dynamic range image ) display and many other advantages, so i...
