Description

Technical Field

[0001] The utility model relates to the technical field of television back panels, and more particularly to a back panel which is convenient for controlling the brightness of a television. Background Art

[0002] The back panel of a TV is an important part of the TV. It is located at the rear of the TV and mainly plays the role of support, protection and heat dissipation. The back panel of the TV provides a stable support for the various components of the TV, ensuring that the TV can be placed and used stably. The back panel can protect the electronic components and circuits inside the TV from damage by the external environment, such as dust, water vapor, vibration, etc. The TV will generate heat when it is working. The back panel is usually designed with heat dissipation holes or heat dissipation structures to help the TV dissipate heat and prevent performance degradation or damage caused by overheating. The utility model proposes a new solution to solve the shortcomings thereof. China Patent Authorization Announcement No. CN221428973U discloses a protective structure for the back panel of a TV, which includes a TV back panel body and a mounting bracket. The surface of the TV back panel body is bolted to the inner wall of the mounting bracket, and a support bracket is provided on the front side of the mounting bracket, and a buffer plate is provided on the front side of the support bracket, and a fixing bracket is bolted to the opposite side of the two buffer plates, and the surface of the fixing bracket is slidably connected with an adjustment mechanism, and a guard plate is bolted to the opposite side of the two mounting brackets, and a protective pad is bonded to the inner wall of the guard plate, which solves the problem that most of the existing TV back panels are not provided with a protective structure, and some office TVs need to be frequently moved during use. Due to the large weight of the TV itself, the TV is prone to collision due to inertia when moving. When the TV back panel collides, it is easy to cause the back panel to deform, which is easy to cause damage to electronic components in severe cases, poor collision resistance, and inconvenience for users.

[0003] Deficiencies of existing technology: The existing TV back panel is installed on the back of the TV body to protect the internal components of the TV. At the same time, the TV back panel also has the function of fixing the TV. However, the adjustment control buttons of most TVs are set on the back of the TV, usually under the partition of the wall, which is inconvenient for TV brightness control and causes trouble to users. In addition, the heat dissipation effect of most TV back panels is poor, and long-term use will cause damage to the internal components of the TV due to high temperature. Utility Model Content

[0023] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely examples. The back panel for facilitating the brightness control of a television set involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 6 The utility model provides a back panel for facilitating the brightness control of a television, including a screen brightness adjustment device 1, the back of the screen brightness adjustment device 1 is electrically connected to a television back device 2, and both ends of the front of the screen brightness adjustment device 1 are bolted to a heat dissipation device 3.

[0025] In this embodiment, it is necessary to specifically explain that the television display presents images through a special backlight source. The performance of the backlight source has an important influence on the brightness of the display screen. The liquid crystal panel emits light of balanced brightness from the backlight source. The light is blocked or controlled by the light of the liquid crystal panel and is formed by the light and shadow of the light. When the brightness of the television needs to be adjusted, the brightness is controlled by sliding the finger on the touchpad 107. The gesture recognition module 106 compiles the finger activity trajectory on the touchpad 107 into computer language, which is then compiled by the processing module and executed by the IC chip 104. The screen brightness adjustment device 1 controls the opening and closing of the liquid crystal molecules through the IC chip 104, thereby controlling the light flux, thereby affecting the brightness of the display screen. This device is conducive to improving the flexibility of the television brightness control. The TV back assembly 2, driven by a motor 303, dissipates heat from the TV through vents 302 to the outside of the TV, helping to reduce damage to internal components caused by high temperatures. The specific structures and operating principles of these components will be described in detail later. The heat dissipation assembly 3 is a crucial component of the TV, located at the rear of the TV and primarily providing support and protection. It should be noted that the operating principle of the backlight source primarily relies on the synergistic effects of a light source such as a light-emitting diode (LED) or a cold cathode fluorescent tube (CCF), and components such as a light guide plate (LGP), a reflective film, a diffuser (DIF), and a brightness enhancement film. The LED or CCF emits light of the desired brightness and color. The LGP converts the side light source into a formal surface light source. Most of the light is refracted to the front, while a small portion is reflected by the reflective film and reused. The diffuser film completely disperses the light, resulting in a relatively balanced light distribution across the entire plane. Finally, the prism-focusing effect of the brightness enhancement film enhances the light in both the horizontal and vertical directions, providing a bright and uniform display. This is prior art, and the backlight source serves only as a light source and is not a technical feature of the present invention.

[0026] In a preferred embodiment, the screen brightness adjustment device 1 includes a liquid crystal component 101, the bottom end of one side of the liquid crystal component 101 is electrically connected to a signal transmission wire 102, one end of the signal transmission wire 102 is electrically connected to a processor 103, the front of the processor 103 is electrically connected to an IC chip 104, one side of the processor 103 is electrically connected to a signal conduit 105, one end of the signal conduit 105 is electrically connected to a gesture recognition module 106, the front of the gesture recognition module 106 is electrically connected to a touchpad 107, one side of the signal conduit 105 is bolted to a machine back protective shell 201, and the liquid crystal component 101 and the processor 103 are both fixedly connected to the front of the machine back protective shell 201.

[0027] In this embodiment, it is necessary to specifically explain that the television display presents images through a special backlight source. The performance of the backlight source has a significant impact on the brightness of the display screen. The liquid crystal panel emits light of balanced brightness from the backlight source. This light is blocked or controlled by the light of the liquid crystal panel and is imaged by the light and shadow of the light. When the brightness of the television needs to be adjusted, the brightness is controlled by sliding the finger on the touchpad 107. The gesture recognition module 106 will compile the finger activity trajectory on the touchpad 107 into computer language, which is then compiled by the processor 103 and executed by the IC chip 104. The IC chip 104 controls the opening and closing of the liquid crystal molecules, thereby controlling the light flux, and thus affecting the brightness of the display screen. This device is conducive to improving the flexibility of television brightness control.

[0028] In a preferred embodiment, the liquid crystal assembly 101 includes a backlight module board 1011, the front of the backlight module board 1011 is electrically connected to the backlight source 1012, the back of the backlight module board 1011 is electrically connected to the first connecting block 1013, and the front of the backlight source 1012 is fixedly connected to the liquid crystal molecular screen 1014.

[0029] What needs to be specifically explained in this embodiment is that the liquid crystal component 101 provides a screen brightness light source through the backlight source 1012. The backlight light is moderate, and the light flux is controlled by the opening and closing of the liquid crystal molecules in the liquid crystal molecular screen 1014 to adjust the screen brightness. This device is conducive to improving the moderateness of the screen brightness.

[0030] In a preferred embodiment, the TV back device 2 includes a back protective shell 201, the back of the back protective shell 201 is provided with a heat dissipation hole 202, the middle bolt on the back of the back protective shell 201 is connected to a second connecting block 203, the top of the second connecting block 203 is welded with a bracket column 204, the bottom of the bracket column 204 is threadedly connected to a base plate 205, and the side bolts of the back protective shell 201 are connected to a protective frame 206.

[0031] What needs to be specifically explained in this embodiment is that the TV back device 2 is an important component of the TV, located at the rear of the TV, and plays a supporting and protective role. The bracket column 204 provides a stable support for the various components of the TV, ensuring that the TV can be placed and used stably, and the back protective shell 201 can protect the electronic components and circuits inside the TV from damage by the external environment.

[0032] In a preferred embodiment, the heat dissipation device 3 includes a heat dissipation fan housing 301, a vent 302 is provided on the back of the heat dissipation fan housing 301, a motor 303 is bolted to the back of the heat dissipation fan housing 301, an intermediate shaft 304 is connected to the front rotating shaft of the motor 303, and a fan blade 305 is bolted to the side of the intermediate shaft 304.

[0033] It should be specifically explained in this embodiment that the intermediate shaft 304 is driven by the motor 303 to evacuate the heat inside the TV to the outside of the TV through the vent 302, which is beneficial to reduce damage to the internal components of the TV due to high temperature.

[0034] The working principle of this utility model:

[0035] When the user needs to adjust the brightness of the TV, he touches the touchpad 107 with his finger. Swiping upwards means turning up the brightness, and swiping downwards means turning down the brightness. The gesture recognition module 106 captures the trajectory of the finger swiping on the touchpad 107 and converts it into a digital signal, which is transmitted to the processor 103 through the signal conduit 105. The processor 103 compiles the transmitted digital signal and determines whether the brightness is reduced or increased. The execution instruction is then passed to the IC chip 104. The IC chip 104 controls the opening and closing of the liquid crystal molecules in the liquid crystal molecular screen 1014. When the instruction is to increase the brightness, the liquid crystal molecules are opened to increase the light flux. If the instruction is to decrease the brightness, the liquid crystal molecules are closed to reduce the light flux, thereby achieving the effect of controlling the brightness.

[0036] A television display presents images through a special backlight source. The performance of the backlight source has a significant impact on the brightness of the display screen. The liquid crystal panel emits light of balanced brightness from the backlight source. This light is blocked or controlled by the light from the liquid crystal panel, and an image is formed by the light and shadow of the light. When the brightness of the television needs to be adjusted, the brightness is controlled by sliding the finger on the touchpad 107. The gesture recognition module 106 will compile the finger movement trajectory on the touchpad 107 into computer language, which is then compiled by the processor 103 and executed by the IC chip 104. The IC chip 104 controls the opening and closing of the liquid crystal molecules, thereby controlling the light flux, which in turn affects the brightness of the display screen. This device is conducive to improving the flexibility of television brightness control.

[0037] The liquid crystal component 101 provides a light source for screen brightness through the backlight source 1012. The backlight light is moderate, and the light flux is controlled by the opening and closing of the liquid crystal molecules in the liquid crystal molecular screen 1014, thereby adjusting the screen brightness. This device is conducive to improving the moderation of the screen brightness. The TV back device 2 is an important component of the TV. It is located at the back of the TV and plays a supporting and protective role. The bracket column 204 provides a stable support for the various components of the TV, ensuring that the TV can be placed and used stably. The back protective shell 201 can protect the electronic components and circuits inside the TV from damage by the external environment.

[0038] The intermediate shaft 304 is driven by the motor 303 to evacuate the heat inside the TV set to the outside of the TV set through the vents 302 , which is helpful to reduce the damage of the internal components of the TV set caused by high temperature.
