Description

Technical Field

[0001] This utility model relates to the field of projection display technology, and more specifically, to a user-friendly desktop projection display. Background Technology

[0002] In today's digital age, displays serve as a crucial interface for human-computer interaction. For a long time, active-emitting displays (AEV) such as OLEDs have dominated the market. These displays achieve efficient and colorful image display through complex electric field driving mechanisms. However, active-emitting light directly shines into the user's eyes, which can easily cause eye fatigue, dryness, and discomfort with prolonged use, and may even cause irreversible damage to vision. Therefore, passive-emitting principles are gradually being adopted for image display. These projection technologies form images on non-light-emitting surfaces (such as screens), and the principle of diffuse reflection gently introduces light into the eyes, effectively alleviating the visual discomfort caused by active-emitting displays. Furthermore, they consume less power, achieving energy conservation and emission reduction.

[0003] However, the projection device is usually placed in front of the projection screen, and the projection device is relatively large, making it inconvenient to place devices such as keyboards and mice, which affects people's work.

[0004] The above shortcomings need to be improved. Utility Model Content

[0005] To address or alleviate the problem that existing projection devices, located in front of the projection screen, are bulky and inconvenient for placing keyboards, mice, and other devices, thus affecting people's work, this utility model provides a user-friendly desktop projection display.

[0006] The technical solution of this utility model is as follows:

[0007] A user-friendly desktop projection display includes a projection screen and a projection device. The projection device includes a projection host for processing image data and a projection optical engine for projecting images. The projection host and the projection optical engine are set up relatively independently and are communicatively connected. The projection optical engine is located behind the projection screen.

[0008] The aforementioned user-friendly desktop projection display includes a wired / wireless communication connection between the projection host and the projection optical engine, and a communication connection between the projection host and the image source device.

[0009] The aforementioned user-friendly desktop projection display has the projection host located at the bottom of the projection screen.

[0010] The aforementioned convenient desktop projection display has a projection screen made of rigid or flexible material.

[0011] The aforementioned convenient desktop projection display includes a light shield between the projection screen and the projection optical engine.

[0012] The aforementioned user-friendly desktop projection display has a frame around the projection screen, and a cable channel for cable routing is provided within the frame.

[0013] Furthermore, a support frame is provided at the bottom of the frame.

[0014] Furthermore, a mounting bracket is provided at the top, left, right, or bottom of the frame, and the projection optical engine is mounted on the mounting bracket.

[0015] Furthermore, the mounting bracket is detachably connected to the frame.

[0016] Furthermore, the surface of the mounting bracket is provided with ribs, which are arranged along the length of the mounting bracket.

[0017] The advantages of this utility model according to the above solution are as follows: By placing the projection engine behind the projection screen, it solves the problem of traditional projection equipment occupying desktop space, allowing users to freely arrange various peripherals on a limited desktop, thus improving the convenience of office and entertainment. Secondly, since the projector and projection engine are relatively independent, users can flexibly adjust their positional relationship according to actual needs to adapt to different usage scenarios and spatial layouts. Furthermore, utilizing the diffuse reflection principle of the projection screen reduces visual fatigue and damage caused by direct light entering the eyes, helping to protect the user's eye health. In addition, compared to traditional active-matrix displays, the projection engine only works when an image needs to be projected, and its energy consumption is far lower than that of active-matrix displays of the same size, contributing to energy conservation and emission reduction.

[0025] like Figure 1 and Figure 2 As shown in the figure, a user-friendly desktop projection display according to one embodiment of the present invention includes a projection screen 1 and a projection device 2. The projection device 2 includes a projection host 201 for processing image data and a projection optical engine 202 for projecting images. The projection host 201 and the projection optical engine 202 are set relatively independently and are communicatively connected. The projection optical engine 202 is located on the back of the projection screen 1.

[0026] The projector 201 and the projector 202 are connected via wired / wireless communication, and the projector 201 is connected to the image source device via communication.

[0027] In this embodiment, the projector host 201 of the desktop projection display is separated from the image source devices such as the computer host. During operation, the projector host 201 receives signals from other image source devices such as the computer host, mobile devices, and storage devices via HDMI, USB, Wi-Fi, Bluetooth, etc. Upon receiving the signal, the image processing chip built into the projector host 201 decodes and optimizes the image data to ensure high definition and color accuracy of the output image. A stable communication connection is established between the projector host 201 and the projection optical engine 202 via wireless or wired communication methods (such as Wi-Fi, Bluetooth, HDMI cable, etc.). The image data processed by the projector host 201 is transmitted to the projection optical engine 202. The dotted and dashed areas in the figure indicate the projection area. After receiving the image data, the projection optical engine 202, located on the back of the projection screen 1, projects the image onto the projection screen 1 using its internal light source, lens group, and other optical components.

[0028] In this embodiment, by placing the projection optical engine 202 behind the projection screen 1, the problem of traditional projection devices occupying desktop space is solved, and the impact on the space behind the user's computer is also minimal. Since modern office computers are generally located in the center of the room, there is sufficient space to place the projection optical engine 202, allowing users to freely arrange various peripherals on their limited desktops for convenient work. Furthermore, placing the projection optical engine 202 behind the projection screen 1 prevents it from touching the user's body, especially their head, and does not obstruct their view. Secondly, since the projector host 201 and the projection optical engine 202 are relatively independent, users can flexibly adjust their positional relationship according to actual needs to adapt to different usage scenarios and spatial layouts, such as embedded installation. Additionally, utilizing the diffuse reflection principle of the projection screen 1 reduces visual fatigue and damage caused by direct light entering the eyes, helping to protect the user's eye health. Moreover, compared to traditional active-matrix displays, the projection optical engine 202 only operates when an image is needed, and its energy consumption is far lower than that of active-matrix displays of the same size, contributing to energy conservation and emission reduction.

[0029] In practical applications, the projector host 201 can also function as a computer host, integrating components such as a motherboard, CPU (Central Processing Unit), memory, and hard disk. This allows for data processing, data storage, control and management, and network communication. Specifically, the CPU and memory process input data and output results; hard disks and other storage devices permanently store data and programs for easy retrieval and modification; the chipset and BIOS on the motherboard coordinate and control various computer components to ensure normal operation; and network cards enable communication and data transmission between the computer and the internet or other computers. In this embodiment, the projector host 201 integrates computer functions for user convenience.

[0030] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the projection host 201 is located at the bottom of the projection screen 1.

[0031] In this embodiment, the projector 201 is placed at the bottom of the projection screen 1 to prevent it from obstructing the projected image. This ensures that the image projected by the optical engine 202 is fully displayed on the projection screen 1, guaranteeing the clarity and integrity of the projection effect, improving the user's visual experience, and allowing the user to enjoy an immersive viewing experience. Furthermore, placing the projector 201 at the bottom of the projection screen 1 lowers the center of gravity of the entire display system, making the system more stable, less prone to tipping or shaking, and improving safety.

[0032] In a preferred embodiment, the projection screen 1 is made of a rigid or flexible material.

[0033] Rigid materials (such as acrylic and glass) have high flatness and light transmittance, ensuring that projected light maintains high clarity and color fidelity when passing through them. At the same time, rigid materials are not easily deformed, effectively resisting external pressure or impact, ensuring the stability and durability of the projected image.

[0034] Flexible materials (such as PVC) can be bent or folded according to actual needs to adapt to projection surfaces of different shapes and sizes, such as curved screens, bringing users a more personalized visual experience.

[0035] Projection screens 1 made of different materials can adapt to different usage environments and needs. For example, rigid materials are suitable for scenarios requiring stable, high-definition projection effects, such as offices and exhibition halls; while flexible materials are more suitable for scenarios requiring portability and flexible placement, such as home entertainment and outdoor activities. This diverse range of material choices allows desktop projectors to be widely used in various fields and occasions. In practical applications, projection screen 1 can be a combination of multiple materials.

[0036] In a preferred embodiment, a light shield is provided between the projection screen 1 and the projection engine 202.

[0037] In this embodiment, the light shield can block ambient light, reducing its interference with the projected image. In brightly lit environments, ambient light often causes the projected image to become blurry and distorted, affecting the viewing experience. The presence of the light shield can significantly reduce this interference, ensuring the clarity and color saturation of the projected image, thereby improving the overall projection effect. At the same time, the light shield can prevent others from viewing the displayed content from behind the monitor, improving privacy.

[0038] In addition, the light shield can also protect the projection optical engine 202. As the core component of the projection system, the projection optical engine 202 contains precision optical and electronic components. The light shield can prevent dust, insects and other impurities from entering the projection optical engine 202, avoiding these impurities from contaminating or damaging the optical components. At the same time, it can also prevent physical damage to the projection optical engine 202 caused by accidental collisions, ensuring the service life of the projection optical engine 202.

[0039] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the projection screen 1 is provided with a frame 3 around its perimeter, and the frame 3 is provided with a cable channel for wiring.

[0040] A support frame 4 is provided at the bottom of the frame 3.

[0041] In this embodiment, the cable tray provides an orderly and concealed routing channel for the cables in the projection system. These cables can be data cables, power cables, etc., connecting the projector host 201 and the projector optical engine 202. Using the cable tray prevents cables from being scattered haphazardly on the desktop or floor, improving the overall aesthetics and creating a cleaner, more organized work environment. It also prevents cables from obstructing the projected image, ensuring projection quality, and protects the cables, reducing safety hazards. Furthermore, the frame 3 enhances the structural stability of the projection screen 1, supporting and securing it to prevent deformation during use. The support frame 4 stably supports the entire projection display, contributing to stable projection performance. The support frame 4 also increases the height of the projection display, reducing its footprint and allowing more office peripherals to be placed on the desktop.

[0042] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a mounting bracket 5 is provided at the top of the frame 3, and the projection optical engine 202 is mounted on the mounting bracket 5.

[0043] The mounting bracket 5 is detachably connected to the frame 3. Specifically, it can be connected via a clamping mechanism such as a spring clip, a snap-fit ​​connection, or a magnetic connection. It can be installed on either side or the bottom of the frame 3 as needed. When installed on the sides, the projection engines 202 of the two back-to-back projection displays can be staggered, reducing space occupation. Similarly, installing one on top of the frame 3 and the other on the bottom of the frame 3 can also save space.

[0044] Ribs 501 are provided on the surface of the mounting bracket 5, and the ribs 501 are arranged along the length of the mounting bracket 5.

[0045] In this embodiment, the detachable connection between the mounting bracket 5 and the frame 3 facilitates the installation and removal of the projection optical engine 202, allowing users to flexibly adjust the position and orientation of the projection optical engine 202 according to actual needs to achieve the best projection effect.

[0046] Mounting bracket 5 can be installed on the sides, top, or bottom of frame 3 as needed, making the layout of the projection system more versatile. In particular, when two back-to-back projection displays need to be installed, by staggering the two projection optical engines 202 on the sides or top and bottom of frame 3, space occupation is reduced and space utilization is improved.

[0047] The ribs 501 on the surface of the mounting bracket 5 improve the structural strength of the mounting bracket 5, reduce its weight, decrease the load on the frame, and improve stability. At the same time, the ribs 501 structure increases the surface area of ​​the mounting bracket 5, which can assist in the heat dissipation of the projection optical engine 202 and help the projection optical engine 202 maintain a stable operating temperature during long-term use.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
