[0005] The purpose of this application is to provide an adjustable brightness touch display in order to solve the problem that the aforementioned adjustable brightness LCD lacks an interactive structure for adjusting the brightness of the display via a touch screen, which makes it inconvenient to use in daily life.

[0006] The technical solution adopted in this application is as follows: An adjustable brightness touch display includes a base, a limiting seat rotatably connected to the surface of the base, a support frame rotatably connected inside the limiting seat, a display screen housing rotatably connected to the top of the support frame, an inner display screen housing installed inside the display screen housing, a display screen installed at the front end of the inner display screen housing, a control console fixedly installed inside the display screen housing and at the side end of the inner display screen housing, a USB port opened at the side end of the display screen housing, a touch display layer fixedly installed inside the inner display screen housing and at the rear end of the display screen, a light guide plate filter layer fixedly installed inside the inner display screen housing and at the rear end of the touch display layer, a light guide plate filter layer fixedly connected inside the inner display screen housing and at the rear end of the light guide plate filter layer, and an LED light source fixedly connected inside the inner display screen housing and at the side end of the light guide plate dot layer.

[0007] By adopting the above technical solution, the LED light source inside the display screen's inner casing is used for output light. The LED light source is transformed from a line light source into a surface light source through the dot layer of the light guide plate. Then, the surface light source is transmitted to the touch display layer and the display screen through the light guide plate filter layer. When no voltage is applied to the light guide plate filter layer, the light source can pass through the light guide plate filter layer with maximum efficiency. As the applied voltage to the light guide plate filter layer is gradually increased, the luminous flux at the light guide plate filter layer will decrease. At this time, less light source passes through, resulting in a darker image when reflected at the touch display layer and the display screen. In use, the host can be operated by touching the icons or text on the computer screen. When it is necessary to adjust the brightness of the display device, the voltage applied to the light guide plate filter layer can be adjusted by sliding the control console, thereby adjusting the luminous flux.

[0008] In a preferred embodiment, a power socket is provided on the side of the display housing and below the USB socket, and a switch is installed on the front surface of the display housing.

[0009] By adopting the above technical solution, the power socket is used for external power input, and the switch allows users to easily control the start-up of the equipment.

[0012] In a preferred embodiment, a mounting base is fixedly connected to the rear end of the display screen housing, and a threaded rod is threadedly connected to the interior of the mounting base. A socket is installed inside the mounting base via the threaded rod.

[0013] By adopting the above technical solution, the insertion socket and the mounting base can be connected and fixed together by the threaded rod.

[0014] In a preferred embodiment, the top of the support frame is provided with a rotating groove, and a damping rotating seat is installed inside the rotating groove.

[0015] By adopting the above technical solution, the socket and the damping rotating seat are fixedly connected, with the socket located at the side end of the damping rotating seat. When the damping rotating seat is rotated, the socket can be rotated, thereby adjusting the orientation of the display screen housing.

[0016] In a preferred embodiment, a side mounting plate is fixedly connected to the surface of the limiting seat, a damping rotating shaft is fixedly connected to the side mounting plate, and a support frame is mounted on the surface of the damping rotating shaft.

[0017] By adopting the above technical solution, rotating the damping shaft can drive the support frame to rotate, thereby adjusting the tilt angle of the support frame.

[0018] In a preferred embodiment, a turntable is rotatably connected inside the base, and a limiting seat is fixedly connected to the surface of the turntable.

[0019] By adopting the above technical solution, the orientation of the display screen casing can be quickly adjusted by rotating the turntable, making it convenient for users to observe the display screen.

[0020] In a preferred embodiment, the rear end of the display screen housing is threaded with an inspection cover, and the rear side of the display screen housing has multiple heat dissipation vents.

[0021] By adopting the above technical solution, the heat dissipation vent can facilitate heat dissipation of the equipment structure inside the display screen housing, and the inspection cover can open the inner shell of the display screen housing, making it convenient for equipment inspection and maintenance.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, the LED light source inside the display screen's inner casing is used for output light. The LED light source is transformed from a line light source into a surface light source through the dot matrix of the light guide plate's dot layer. Then, the surface light source is transmitted to the touch display layer and the display screen through the light guide plate's filter layer. When no voltage is applied to the light guide plate's filter layer, the light source can pass through the filter layer with maximum efficiency. As the applied voltage to the light guide plate's filter layer gradually increases, the luminous flux at the filter layer decreases, resulting in less light passing through and a darker image when reflected at the touch display layer and the display screen. During use, the host computer can be operated by touching icons or text on the computer screen. When adjusting the brightness of the display device, the voltage applied to the light guide plate's filter layer can be adjusted by sliding the control console, thereby adjusting the luminous flux. When adjusting the angle of the display device, the display screen casing can be held and rotated vertically, or the support frame can be held and adjusted horizontally.

This surface light source is then transmitted to the touch display layer 25 and the display screen 10 through the light guide plate filter layer 24. When no voltage is applied to the light guide plate filter layer 24, the light source can pass through it with maximum efficiency. As the applied voltage to the light guide plate filter layer 24 gradually increases, the luminous flux at the light guide plate filter layer 24 decreases, resulting in less light passing through. This is reflected in the touch display layer 25 and the display screen 10 as a darker image. During use, the host computer can be operated by touching the icons or text on the computer screen. When adjusting the brightness of the display device, the control console 8 can be slid to adjust the voltage applied to the light guide plate filter layer 24, thereby adjusting the luminous flux.

The power socket 21 is used for external power input, and the switch 11 allows users to easily control the start of the equipment.

[0034] Reference Figure 1 Multiple indicator lights 12 are installed on the surface of the display housing 7 and on the side of the switch 11. The indicator lights 12 are used to display the working signals of the device. When adjusting the brightness, the control panel 8 can remind the user of the adjustment signal by flashing the indicator lights 12. When the leftmost indicator light 12 is lit, it means that the screen is at maximum brightness. When the last indicator light 12 is lit, it means that the screen is at minimum brightness. When the middle indicator light 12 is flashing, it means that the brightness is being adjusted.

[0035] Reference Figure 2 and Figure 3 The rear end of the display housing 7 is fixedly connected to a mounting base 16. A threaded rod 17 is threadedly connected inside the mounting base 16, and a socket seat 15 is installed inside the mounting base 16 through the threaded rod 17.

The LED light source is transformed from a line light source to a surface light source through the dots of the light guide plate dot layer 23. Then, the surface light source is transmitted to the touch display layer 25 and the display screen 10 through the light guide plate filter layer 24. When no voltage is applied to the light guide plate filter layer 24, the light source can pass through the light guide plate filter layer 24 with maximum efficiency. When the applied voltage to the light guide plate filter layer 24 is gradually increased, the light flux at the light guide plate filter layer 24 will decrease. At this time, less light source passes through, and the effect reflected at the touch display layer 25 and the display screen 10 is a darker image. In use, the host can be operated by touching the icons or text on the computer screen. When it is necessary to adjust the brightness of the display device, the voltage applied to the light guide plate filter layer 24 can be adjusted by sliding the control console 8, thereby adjusting the light flux. When adjusting the angle of the display device, the display casing 7 can be held and rotated vertically, or the support frame 6 can be held and adjusted horizontally. When adjusting the height of the display casing 7, the support frame 6 can be held and adjusted vertically. The power socket 21 is for external power input, and the switch 11 allows users to easily control the device's start-up. The indicator lights 12 display the device's operating signals. When adjusting brightness, the control panel 8 can use the indicator lights 12 to flash, indicating that the screen is at maximum brightness when the leftmost indicator light 12 is on, at minimum brightness when the rearmost indicator light 12 is on, and in progress when the middle indicator light 12 is flashing. The heat dissipation vent 19 facilitates heat dissipation from the internal structure of the display casing 7, and the inspection cover 18 allows opening the inner casing 9 of the display casing 7 for easy inspection and maintenance. This device allows for quick adjustment of the display device's height and angle, and quick adjustment of the touch display's brightness, improving its usability.
