Abstract
Description
Technical Field
[0001] This utility model relates to the field of display devices, and in particular to a portable, modular touch-sensitive display. Background Technology
[0002] As is widely known, the first monitor was the CRT monitor, which was born in 1922. Its bulky size and curved screen remained unchanged for about sixty years. With the continuous upgrading of LCD technology, it gradually replaced the CRT monitor. The subsequent OLED display technology has continued to develop and has become the mainstream. Later, with the advancement of display technology, the image quality became higher and higher. However, today's software is becoming more and more touch-operated, such as video clients, casual games, office drawing, etc. The role of touch screen monitors is becoming more and more important. In 1967, the first capacitive touch screen was born. To this day, touch screens have become more and more portable, sensitive, and accurate. The combination of touch screens and monitors has given birth to touch screen monitors, which better meet the needs of users.
[0003] As shown in the modular assembly structure of a multi-screen display disclosed in Chinese Utility Model Patent No. CN216353106U, it demonstrates the improvement of the prior art in terms of display structuring. It uses a bending plate and torsion spring, along with a clamping plate, to achieve the purpose of assembling the LED display screen with the assembly frame. It eliminates the need to install and fix multiple LED displays before assembling them onto the assembly frame, realizing the function of assembling each LED display screen individually with the assembly frame, which greatly improves the assembly efficiency. However, for a single display screen itself, the current method still uses an integral shell frame, resulting in a limited range of applications. The non-modular structure cannot be freely assembled and expanded, and it is expensive. If the shell frame structure is enlarged in advance to reserve installation positions and interfaces for parts, it will increase the volume and cost, and make it inconvenient to carry.

In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.
[0021] Combined with appendix Figure 1-4 The portable, modular touchscreen display includes an outer shell 2 and a touchscreen 1 installed in the slot of the outer shell 2. The slot of the outer shell 2 is perfectly fitted to accommodate the touchscreen. To ensure stable installation of the touchscreen 1, a step is provided in the slot of the outer shell 2 to abut the edge of the back of the touchscreen 1. This step is provided on the inner side of at least two of the four slot walls of the outer shell 2 symmetrically to ensure stable contact. The upper and lower slot walls of the outer shell 2 both have corresponding retaining strips 201 extending inward to abut the corresponding front edge of the touchscreen 1. The retaining strips 201 and the steps are used to clamp and fix the touchscreen 1 inside and out. The outer shell 2 is assembled from multiple modular units that can be disassembled and assembled, as shown in the attached figure. Figure 2 and 4 The assembly details of the building block units shown are as follows: each end face of the building block unit is provided with a plug and slot that can be inserted and matched, so that any two building block units can be connected end to end. Each side wall of the building block unit is provided with a snap-fit structure that can be snapped into the side wall of the adjacent building block unit, so that any two building block units can be connected from the side. Of course, the snap-fit part 201 is also assembled from multiple building block units, which ensures the convenience of disassembling and assembling the touch screen 1.

The display panel and touch sensor are respectively connected to a display driver circuit board and a touch driver circuit board. The display driver circuit board is connected to a speaker 8, a button control board 3, an HDMI interface 6, a VGA interface 5, and a power interface 4. The touch driver circuit board is connected to an external connection port 7 to ensure that the touchscreen supports multiple input signals and has a built-in amplifier that can synchronously play audio signals from HDMI. In addition, there are two speakers 8, which are divided into left and right channels. Two sound holes are symmetrically arranged at both ends of the bottom of the outer shell 2. The inner end of the sound holes is covered with a cover for fixing the speaker 8. The first cover 202 ensures that the speaker 8 is fixed stably while the speaker opening aligns perfectly with the sound vent. The upper ends of the bottom of the outer casing 2 are respectively provided with a first slot 203 and a second slot 204 for mounting the display driver circuit board and the touch driver circuit board. The upper wall of the outer casing 2 has an exposed opening corresponding to the external connection port 7, HDMI interface 6, VGA interface 5, and power interface 4. The inner wall of the outer casing 2 near the first slot 203 is covered with a second cover 20 for fixing the button control board 3. 5. The outer casing of the corresponding button control panel 3 has side openings on the groove wall to expose each button on the button control panel 3; the first cover part 202, the second cover part 205, the first slot part 203, and the second slot part 204 are all assembled from building block units, and are distinguished from the outer casing 2 by different colors to clearly indicate their positions and functions, making it easy to disassemble, modify, and maintain; if other hardware needs to be fixed on the touch display in the future, it can be fixed at any position on the touch display simply by properly encapsulating the hardware with building block units.
[0023] The portable, modular touchscreen display described in this utility model allows for the selection of various components based on usage scenarios and individual needs. These components are then assembled using modular units to create the required outer shell 2, forming a complete touchscreen display. During use, power is supplied to the display driver circuit board of the LCD panel. The computer's video output interface is connected to the corresponding interface on the LCD panel's display driver circuit board, and the touch sensor's touch driver circuit board is connected to the corresponding interface on the computer. Pressing the power button on the control panel 3 automatically adjusts the display to the corresponding interface. If the touchscreen 1 includes an amplifier, the volume can be adjusted via the control panel 3. Switching between portrait and landscape display or between the main and secondary screen positions can be done through the "Display Settings" on the computer interface.
