[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood in specific circumstances. Multiple technical solutions in the same embodiment, as well as multiple technical solutions in different embodiments, can be arranged and combined to form new technical solutions without contradictions or conflicts, all within the scope of protection required by the utility model.

[0024] After the fiber-optic broadband network is now connected to the home, the modem and wireless router are generally placed at the entrance. However, with the increase in the number of smart devices that need to connect to wireless signals, in houses with large areas or long depths, smart devices are placed in various places in the house, and the distance from the fiber-optic broadband network varies. Some smart devices are far away from the fiber-optic broadband network, and the network quality of the fiber-optic broadband network for the smart device is very poor, far from meeting the data transmission rate and bandwidth requirements required by the smart device.

[0025] In order to solve the above problems, three solutions are generally adopted in the known technology.

[0026] The first solution is to place the modem and wireless router in the living room. Although this solution can improve the network quality for smart devices that need to connect to wireless signals, placing the modem and wireless router directly in the living room is not only unsightly, but also easy to accidentally touch and cause network interruption.

[0027] The second solution is to configure a signal repeater or amplifier for Wi-Fi signals in places where the wireless signal is weak or near places where the wireless signal is weak. The repeater or amplifier can realize the relay and amplification of Wi-Fi signals only after a series of configurations. This method requires additional equipment, which is cumbersome to operate and configure, and the user experience is not good. In addition, the presence of the repeater will restore the received attenuated signal to its original state and then forward it, which may cause signal delay or loss, thereby reducing network quality.

[0028] The third solution is to integrate a wireless signal transceiver module on the LED (Light-Emitting Diode) lamp. This module is used to replace the wireless router at the entrance. The wireless signal transceiver module is mainly used to receive WiFi signals. However, the module itself does not have the functions of modulation and demodulation and wireless routing, so it cannot replace the modem and wireless router. Although this solution can solve the problem of poor network quality provided by the fiber-optic broadband network for various smart devices to a certain extent, the location of the LED lamp is generally far away from the network cable interface, and there are many inconveniences in the actual implementation of the solution.

[0029] In order to solve the above problems, the present application proposes a projection display device.

[0030] With the increase of smart devices, the demand for wireless networking has also increased sharply. Projection equipment has also entered thousands of households, but massive video resources need to be obtained through the network. With the development of ultra-high-definition video signals, the requirements for data transmission efficiency and bandwidth are getting higher and higher.

[0031] The resulting problem is that in a house that is large or too deep, the modem and wireless router placed at the entrance cannot provide wireless signals that meet the network quality requirements of each smart device throughout the house.

[0032] Therefore, the present application provides a method of integrating a wifi wireless signal transceiver module into a commonly used projection display device in a home. The projection display device includes an intelligent projection device, an ordinary rear-projection TV, a projector, an ultra-short-throw laser TV, etc., giving full play to the advantage of the projection display device being located in the center of the house, so that the wireless signal can cover the entire house, avoiding the inconvenience caused by using wireless routers or wireless repeaters, and ensuring the data transmission rate and bandwidth requirements when the projection display device plays ultra-high-definition video signals, while ensuring the problem of wireless signal coverage throughout the house.

[0033] See also Figure 1 , a composition structure diagram of the projection display device provided in this application.

[0034] like Figure 1 As shown, the projection display device mainly includes a light source module 1, an optical machine module 2, a central control circuit control module 3 and a wireless signal transceiver module 4.

[0035] The light source module 1, the optical machine module 2, the central control circuit module 3 and the wireless signal transceiver module 4 are connected in sequence.

[0036] Among them, the light source module 1 is mainly used to generate light for generating images. Specifically, the light source module 1 provides the necessary lighting to display images and is one of the core components of the projection display device. The types of light sources provided include ultra-high pressure mercury lamps, LED lamps, lasers, and the like. Among them, the LED light source is a commonly used light source for intelligent projection, with low power consumption and long life. The laser light source can combine the advantages of traditional light sources and LEDs, can provide high brightness and wide color gamut, low heat generation, and long life. It can be seen that the choice of light source has an important influence on the performance of the projection display device, such as brightness, color performance, etc., which is related to the clarity and quality of the projected image.

[0037] The optical-mechanical module 2 is connected to the light source module 1, and includes multiple components, such as a light combining module, an illumination module, an imaging module, and a DMD (Digital Micromirror Device) chip, etc. These components together complete the task of converting the light emitted by the light source module 1 into a visible image.

[0038] Among them, the chip is the key component that determines brightness and physical resolution. Each micromirror represents a pixel, and the light is modulated by precisely controlling the angles of these micromirrors to form an image. The optical-mechanical module 2 also includes components such as a color wheel or a beam splitter prism, which are responsible for synthesizing light into different colors, thereby being able to reproduce rich color levels. Different types of light source modules 1 and optical-mechanical modules 2 are precisely matched to achieve the best display effect.

[0039] The central control circuit control module 3 is mainly used to realize the centralized management and control of the projection display device. In the central control circuit control module 3 provided in the present application, a wireless signal transceiver module 4 is integrated. The wireless signal transceiver module has the functions of modulation and demodulation and wireless routing, and can replace the optical modem and wireless router. Generate wireless signals to provide wireless signals for itself and other smart devices in the house.

[0040] The wireless signal transceiver module includes an optical modem, a network connection port and a wireless communication module. Among them, the optical modem is mainly used to receive fiber-to-the-home signals. The network connection port is an 8-bit modular network connection port, such as an RJ-45 interface. The optical modem, network connection port and wireless communication module in the wireless signal communication module are connected in sequence, and the wireless communication module converts the fiber-to-the-home signal received from the optical modem into a wireless signal and transmits it into space.

[0041] For example, see Figure 2 , a composition diagram of the wireless signal transceiver module provided in this application.

[0042] like Figure 2 As shown, the network connection port is an RJ-45 interface, and the wireless communication module is a wifi communication module 30 .

[0043] The wireless signal transceiver module 4 includes an optical modem 10 , an RJ-45 interface 20 and a wifi communication module 30 .

[0044] The optical modem 10 is used to receive fiber-to-the-home signals, convert the optical signals into electrical signals, and then connect to the wifi communication module 30 through the RJ-45 interface 20, and the wifi communication module 30 converts the electrical signals into wireless signals and transmits them into space.

[0045] The wifi communication module 30 includes a wireless network card and a wireless access point. The wireless network card mainly provides wireless data transmission function for the projection display device, and the wireless access point is also called AP, which mainly provides wireless network access service for the projection display device.

[0046] For example, see Figure 3 , a composition structure diagram of the wifi communication module provided in this application.

[0047] like Figure 3 As shown, the wifi communication module 30 includes a wireless network card 100 and an AP 200 .

[0048] The projection display devices provided in this application include ordinary rear-projection TVs, projection devices, and ultra-short-throw laser TVs, etc. Taking advantage of the fact that these projection display devices are generally placed in the center of the house, the wifi signal fully covers the entire house, cleverly avoiding the inconvenience caused by using wireless routers or wireless repeaters. It can not only ensure the transmission efficiency and viewing experience when the projection display device plays ultra-high-definition video signals, but also solve the problem of wifi signal coverage throughout the house.

[0049] In addition to the above modules, it also includes a lens and a display device housing. The light source module, the optical machine module, the central control circuit control module and the wireless signal transceiver module are placed in the display device housing.

[0050] To summarize, the projection display device disclosed in the present application includes a light source module, an optical machine module, a central control circuit control module and a wireless signal transceiver module connected in sequence. A wireless signal transceiver module with integrated modulation and demodulation and wireless routing functions is added to the projection display device, so that the projection display device can replace the modem and wireless router generally installed at the entrance of the house to provide wireless signals for the whole house. It can not only meet the data transmission rate and bandwidth requirements required by the projection display device, provide high-quality network, and ensure the user's viewing experience, but also cover the whole house with wireless signals, making it convenient to provide wireless networks for other smart devices.
