Description

LED display with screen hiding function

Technical Field

The utility model belongs to the LED display field, concretely relates to LED display of hidden screen function in area.

Background

The LED display is very extensive in application, the LED display can be used in almost all trades at present, especially some household electrical appliances and house field, the application demand of LED display is very big, for example in the aspect of the bathroom, need install the LED display on tap, the water pipe etc. can show real-time temperature, as shown in fig. 1, current LED display mainly includes and moulds the shell 3, set up circuit board 2 in moulding the shell 3, set up in the display film 4 at moulding the shell 3 top, mould 3 last digital window and the function display window that has special design of shell, light display film 4 through the wick on circuit board 2, and show real-time figure, install this kind of LED display on the water pipe 100 of water heater, there are some problems in the in-service use, specifically as follows:

1. because the display film 4 is in the non-lighting state, the digital window and the functional display window of the plastic shell 3 can be clearly displayed on the display film 4, so that people can be misled to touch the display film 4 with hands to realize operation, especially children or public places, the problems of displacement, separation, deformation and the like of the display film 4 can be caused by frequent touch of the display film 4, the use effect of the display film 4 is influenced, and the service life of the display film 4 is also shortened.

2. Because the LED display is in a watery and humid environment for a long time, the requirement on the sealing performance of the LED display is high, the sealing performance of the existing LED display cannot achieve the using effect, water easily enters the LED display, and particularly the use of the LED display is directly influenced if the LED display contacts the circuit board 2.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the LED display with the screen hiding function is provided, the LED display realizes the complete shielding and hiding of a digital window and a functional display window under the condition of no lighting, people cannot be misled to contact the display film, the display film is prevented from shifting, separating, deforming and the like due to frequent touch, and the LED display has good sealing and water releasing performance, prevents water from contacting a circuit board, and ensures the continuity, stability and good use effect of the LED display.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a LED display of hidden screen function in area, including moulding the shell, setting up circuit board in moulding the shell, set up in the display film at moulding the shell top, still include backshell and transparent dark panel, it is located the backshell to mould the shell, transparent dark panel mounting is on the backshell, transparent dark panel covers the display film, transparent dark panel is used for sheltering from the display film when not being in luminescent state.

Further, the transparent dark panel is provided with a mounting hole, the mounting hole extends into the transparent dark panel to form a sealing part, and a sealing ring is sleeved on the sealing part. The transparent dark panel can be selected from dark transparent glass materials.

Further, the sealing washer is the silica gel circle, and the effect of sealing washer lies in preventing that water from getting into.

Furthermore, a 3M glue layer is arranged on the connecting surface of the rear shell and the transparent dark-color panel, and the 3M glue has excellent viscosity, so that the connecting strength of the rear shell and the transparent dark-color panel is ensured.

Furthermore, a lead window is arranged on the rear shell and used for leading out a lead of the circuit board.

The design principle of the utility model is that: the display film is covered by the transparent dark color panel, and due to the unique performance of the transparent dark color panel, when the LED display is in a non-lighting state, the digital window and the functional display window can be completely shielded by the transparent dark color panel, no digital and pattern display exists on the transparent dark color panel, the misleading contact operation can be avoided, the display film is hidden, and the use of the display film is guaranteed.

Has the advantages that: compared with the prior art, the utility model, possess following advantage

1. When the LED display is in the unlighted state, the digital window and the functional display window can be completely shielded by the transparent dark-color panel, no numbers and patterns are displayed on the transparent dark-color panel, the contact operation cannot be misled, the display film is hidden, the display film is prevented from being touched by users, and the display film is prevented from shifting, breaking away from, deforming and the like easily due to frequent touch.

2. The sealing ring improves the sealing performance between the transparent dark color panel and the mounting part, has good sealing and water releasing performance, prevents water from contacting the circuit board, and ensures the continuous, stable and good use effect of the LED display.

3. Due to the special performance of the transparent dark color panel, when the LED display is in a lighting state, the transparent dark color panel can only display numbers and patterns, and can not display the outlines of a number window and a pattern window completely, so that the display effect is improved, and the grade of the product is improved.
