[0004] Chinese patent applications 200610011431.3, 200580006886.X, 200410031715.X, 200710073725.3, and 200580027868.X all disclose technical solutions for realizing projection functions on mobile communication devices, but some of these technical solutions only describe the idea of ​​combining mobile phones and projectors , some describe the connection method between the mobile device and the projector or the signal drive and circuit control method, some have a complex structure and large size, and some lack substantial content and are difficult to realize. Only another Chinese patent application 200610079488.7 discloses a relatively mature mobile phone A technical solution combined with a miniature projector, which describes the structure of the projector in detail
Although the single-chip liquid crystal projection system can obtain a projector module with a compact structure, a small size, a light weight, and a low cost, it has brought serious disadvantages: poor display quality, dark brightness, and inability to project satisfactory images on the external screen. image

Embodiment 1

[0026] Please refer to figure 1 , the projector module used in the present invention is mainly composed of a light source assembly 1w, a light splitting system, a micro-display chip and a projection lens 5, wherein the light source assembly 1w includes a light source and a focusing shaping lens. In this embodiment, a white light source is used. Specifically, it can be a white LED point light source or a surface light source; the splitting and combining system is a flat polarizer 2, which can convert the light emitted from the light source module 1w into polarized light and divide it into S polarized light and P polarized light The micro display chip comprises two adjacent LCOS liquid crystal panels 3 and 4 which are arranged orthogonally, wherein the LCOS liquid crystal panel 3 receives the S polarized light reflected from the flat polarizer 2, and the LCOS liquid crystal panel 4 receives the S polarized light transmitted from the flat polarizer 2. P polarized light. The LCOS...

Embodiment 2

[0028] Please refer to figure 2 , the projector module uses a three-color light source, including a red light source assembly 1r, a blue light source assembly 1b, and a green light source assembly 1g. Blocks of LCOS liquid crystal panels 3 and 4 are arranged adjacently and orthogonally. Among them, the red light source assembly 1r, the blue light source assembly 1b and the green light source assembly 1g are all composed of LED light sources and focusing shaping lenses. The three-color light source assemblies are adjacently arranged on three sides of the X-cube light combining prism. The structure is compact and the volume is small. The emitted red light, blue light and green light enter the X-cube light-combining prism and are synthesized into a beam of light, which is sent to the flat polarizer 2 and divided into S polarized light and P polarized light, wherein the LCOS liquid crystal panel 3 receives the light from The S polarized light reflected by the flat polarizer 2 , ...

Embodiment 3

[0030] See image 3 As shown, the structure of the projector module in this embodiment is similar to that of Embodiment 2, including three-color light sources: red light source assembly 1r, blue light source assembly 1b and green light source assembly 1g, the difference is that the light splitting system does not use X- The cube light combining prism uses two dichroic mirrors 7 and 8, which reduces the weight of the whole machine. The light path of the projection system is as follows: red light is transmitted through the first dichroic mirror 7 and the second dichroic mirror 8, blue light is transmitted through the second dichroic mirror 8 after being reflected by the first dichroic mirror 7, and green light is transmitted through the second dichroic mirror 8. Reflected by the dichroic mirror 8, the red, green and blue light finally synthesizes a beam of light and enters the flat polarizer 2, and the flat polarizer 2 converts the input light into P polarized light and S polari...

Abstract

The invention discloses a mobile device embedded with a projector module. The mobile device is equipped with a signal driving unit and a control unit of the projector module. The projector module is mainly composed of a light source component, a light splitting and combining system, micro-display chips and a projecting lens, wherein light sent by the light source component is emitted to the micro-display chips via the light splitting and combining system, after being modulated, the light carrying image information is output to an external screen from the projecting lens, in which the light source component is red, green and blue three colors; the light splitting and combining system comprises a flat polarization apparatus and an X-cube light combination prism, the three colors of read, green and blue is combined through the X-cube light combination prism and emitted into the flat polarization apparatus, and the micro-display chips are two LCOS liquid crystal panels which are disposed perpendicular adjacently. While the light source, the light splitting and combining system, the micro-display chips and the projecting lens are all miniaturization devices. The projector module of the invention is more miniaturized. Besides the adoption of two LCOS liquid crystal panels increases the light utilization ratio and improves the display quality.

Description

technical field [0001] The present invention relates to a projection display device, in particular to a mobile device equipped with a projector module capable of realizing a projection display function. Background technique [0002] In the 21st century, image display technology has been greatly developed, and it is widely used in portable electronic products, such as notebook computers, mobile phones, game consoles, media players, and other mobile devices that require image display. However, due to the small size of these mobile devices, the size of their display screens is greatly limited, and consumers will not be satisfied with the small screen display functions of mobile devices, especially in e-commerce activities, people expect easy-to-carry and easy-to-use Projection-enabled mobile devices appear for product or solution demonstrations. [0003] People have already produced projector products with good display quality and large-screen viewing images, but these project...
