Description

Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a light-emitting marking structure for a display screen. Background Technology

[0002] In the commercial display industry, the appearance design and functional practicality of display devices, especially large-screen display devices (such as interactive whiteboards for teaching and conference tablets), are among the core concerns of users. The markings on the device frame (such as brand logos and device function markings) are an important part of users’ identification of device attributes, brand recognition, and perception of the integrity of the display screen’s appearance.

[0003] Currently, logos on large-screen display devices are generally implemented in two ways: one is through screen printing, where the logo is directly printed onto the bezel surface; the other is through nickel-plated bonding, where a pre-made nickel-plated logo is pasted onto a designated location on the bezel. Both methods have significant drawbacks. First, the existing logos are static and cannot convey the display's operating status (such as power on / off), requiring additional indicator lights on the bezel, complicating the bezel structure and compromising its overall integrity. Furthermore, after prolonged use, screen-printed logos are prone to wear, and nickel-plated logos are prone to detachment, resulting in low reliability. Utility Model Content

[0018] The technical solution provided by this utility model is further illustrated below with reference to the embodiments.

[0019] This embodiment provides a light-emitting marking structure for a display screen, the display screen including a display screen body and a frame for mounting the display screen body, such as... Figure 1As shown, the frame has several through holes forming an identification pattern 5. These through holes are translucent. An installation space is formed inside the frame, and a light guide plate 3 covering the through holes is installed within this space. The power cord of the light guide plate 3 is connected to the main control board of the display screen. When the display screen is powered on, the light guide plate 3 emits light, which passes through the through holes to form the luminous identification pattern 5. This luminous identification pattern 5 serves not only as an identifier but also as an indicator light confirming that the display screen is on. When the display screen is powered off, the light guide plate 3 also loses power, and the identification pattern 5 stops emitting light, indicating that the display screen is off. If the display screen is used as teaching or conference equipment, the screen will not attract user attention when the identification pattern 5 stops emitting light. The frame has a shape that surrounds the display screen, typically a rectangle, consisting of a top frame, two side frames, and a bottom frame. The identification pattern 5 can be located in the bottom frame of the frame, and its display effect is as follows. Figure 3 As shown, Figure 3 In the example, logo 5 uses the "Classin" logo.

The angle between the inner frame top wall and the inner frame side wall, and the angle between the inner frame bottom wall and the inner frame side wall, are 90 degrees. The outer edge of the display screen body contacts the inner frame bottom wall, thereby protecting the edge of the display screen body. At least a portion of the back of the display screen body contacts the inner frame side wall, which can increase the connection area and achieve stability.

[0026] The display screen body includes: an infrared touch display screen body; the infrared touch display screen body includes: an infrared touch display panel for display and an infrared touch panel 6 connected to the infrared touch display panel; the infrared touch panel 6 is installed in the mounting space inside the frame; the infrared touch display panel is connected to the outside of the frame, and the frame surrounds the outer edge of the infrared touch display panel, protecting the outer edge of the infrared touch display panel.

[0027] The inner frame 2 is provided with a mounting groove 8 for mounting the infrared touch panel 6; the mounting groove 8 is connected to the inner frame side wall of the inner frame 2.

[0028] like Figure 2 As shown, the luminous marking structure also includes an infrared filter strip 7, located between the light guide plate 3 and the infrared touch display panel, used to filter the infrared light emitted by the light guide plate 3. The frame has a notch for mounting the infrared filter strip 7; at the notch, the outer frame 1 has an L-shaped cross-section, with an outer frame side wall and an outer frame bottom wall; the outer frame side wall is detachably connected to the inner frame top wall, and the outer frame bottom wall is located below the inner frame, thus forming a notch between the free end of the outer frame bottom wall of the outer frame 1 and the free end of the inner frame bottom wall of the inner frame 2; the infrared filter strip 7 covers the notch; a protrusion 9 is provided at the free end of the outer frame bottom wall, and an mounting groove matching the protrusion 9 is provided through the infrared filter strip 7, allowing the infrared filter strip to be mounted through the cooperation of the protrusion 9 and the mounting groove.
