Abstract

The invention discloses a micro LED projector for a mobile phone, and relates to a projector, in particular to a micro projector arranged on the mobile phone. The micro LED projector comprises a mobile phone casing, a control system, an imaging device and a projection lens, wherein the control system and the imaging device are arranged in the mobile phone casing; the projection lens is arranged on the surface of the mobile phone casing; the imaging device is electrically connected with the control system. The control system comprises a video signal processing unit, a display control unit, a display chip and a power supply, wherein the signal output interface of the video signal processing unit is in signal connection with the signal input interface of the display control unit; the signal output interface of the display control unit is in signal connection with the signal input interface of the display chip; the video signal processing unit, the display control unit and the display chip are electrically connected with the power supply respectively. The micro LED projector has the benefits that light paths are reduced, the electricity-to-light conversion efficiency is improved, and the utilization ratio is increased; white light and a color wheel are not needed, so that a smaller size can be achieved, and micro projection is truly realized.

Description

technical field [0001] The invention relates to a projector, in particular to a miniature projector arranged on a mobile phone. Background technique [0002] At present, there are mainly two kinds of mobile phone micro-projectors on the market: LCOS projection technology and DLP projection technology. The main principle of LCOS projection technology is based on the principle of LCD light valve. The LCD panel is used to control the amount of light passing through the light source to form an image, and the light is enlarged and projected onto the screen through the lens. The main working principle of DLP projection technology is based on the DMD digital micromirror, which adjusts the time ratio of reflection and non-reflection to display images. However, for DLP micro-projectors, a backlight is required, and the volume is relatively large, and the shock resistance of DMD displays is relatively poor; for LCD micro-projectors, a backlight is also required, and the volume is re...
