Abstract
The invention discloses a light guide LED lamp panel, which comprises a light guide layer and a first LED chip array embedded in the light guide layer; the light emitting surface of the first LED chip is perpendicular to the plane of the light guide LED lamp panel, so that the emitted light of the first LED chip is emitted out through the uniform surface light source after being mixed by the light guide layer. The invention reduces the thickness of the backlight source module; and by converting the point light source into the surface light source, the requirements on the brightness and uniformity of the backlight source can be met under the condition of using a small number of LED lamps, and the assembly cost of the backlight source module is reduced.
Description
Technical Field
The invention relates to a display device, in particular to a light guide LED lamp panel.
Background
With the rapid development of display technology, people have increasingly high demands on displays, and particularly, demands on non-planar display devices such as flexible liquid crystal displays, curved liquid crystal displays, flexible liquid crystal displays, and foldable liquid crystal displays have increased. The flexible liquid crystal display panel is about to become the mainstream of the display field by virtue of its characteristics of lightness, thinness, bendability and impact resistance. However, the liquid crystal display device is a non-self-luminous display device, and the display can be realized only by matching with backlight, thereby greatly increasing the difficulty of flexible display. How to implement a flexible backlight has been an unsolved problem.
The direct type backlight module is directly arranged behind the liquid crystal display panel, has the advantage of a narrow frame, is widely applied to the field of large-size display, and faces the problem of thickness increase. A Mini light emitting diode (Mini-LED) is a small LED having a size of about 100 μm, and when the Mini-LED is applied to a backlight unit, it is possible to reduce the increase in thickness of a liquid crystal display device while realizing a narrow bezel. Similar to the conventional side-in backlight module, the vertical backlight module using Mini-LEDs also needs to use a brightness enhancement film, a reflector plate, etc. to improve the front brightness. The basic principle of the most commonly used brightness enhancement film is that part of the light with large angle can be converged to the central region, and the rest of the light can re-enter the light guide plate through total reflection and be recycled. Different from a light guide plate light returning system of a side-in type backlight, a vertical backlight module of a Mini-LED is designed without a light guide plate, but light returning is carried out by coating white light reflecting ink (namely white oil) on a driving substrate, and due to the reflection characteristic of the white oil, the reflected light and incident light generally have the same angle, or the reflected light enters a brightness enhancement film again after being reflected and is totally reflected back, or the reflected light is reflected to a low reflection area (such as the surface of the Mini-LED and a spacer area between the Mini-LED and the white oil) of the driving substrate and is lost, so that the whole light returning efficiency is greatly lost, and the light emitting efficiency is not high. The flexible Mini-LED backlight technology is difficult to implement, is disjointed from the traditional backlight technology on the one hand, and has high manufacturing cost and low yield on the other hand.
