Abstract

The invention discloses a luminous module hidden under a mobile phone screen. The luminous module includes a screen component, a micro backlight illuminating system installed under the screen component, a liquid crystal display (LCD) screen arranged under a glass cover plate, and a light guide plate which is arranged under the LCD screen and used for illuminating the LCD screen; the screen component includes the glass cover plate; a second through hole is formed in the center of the light guide plate, a second luminous component can be arranged under a light guide component according to needsto achieve the luminous effect, and an imaging system can be arranged under the light guide component to achieve the function of flashing and imaging integration. The luminous module is simple in structure, low in cost, long in life and good in reliability, meanwhile, dark spots, caused by opened holes of the light guide plate, on the display screen can be eliminated, the luminous module can be applied in ordinary LCD touch screens, flash lamps, iris recognition or 3D imaging structured light and other under-screen luminous modules.

Description

technical field [0001] The present invention relates to a flashlight module, more specifically, relates to a light-emitting module hidden under the screen of a mobile phone. Background technique [0002] When people use a camera or video camera to shoot, they are often at night or when the ambient light is not good, so they usually need to be equipped with auxiliary equipment to enhance the light effect. As a common light reinforcement device, the flashlight has been used It is widely used in photography art. With the improvement of users' requirements for photographic effects, the requirements for flashlights in photographic equipment have also increased accordingly. The flashlight modules that are popular in the market for mobile phones are generally set to be visible to the naked eye, which affects the appearance of mobile phones. In particular, the front camera generally adopts a flash plus imaging structure, which will cause two obvious camera components to appear on t...
