In the description of the present application, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In addition, in the description of the present application, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1-4, the embodiment of the present application provides an interactive display large screen, which includes a large screen body 1, and a sound pickup circuit board 32, a sound pickup device and an LED lamp set are provided on the large screen body 1, the sound pickup device includes a sound pickup circuit board 31 and a sound pickup module provided on the sound pickup circuit board 31, the sound pickup circuit board 32 is electrically connected with the sound pickup circuit board 31 to control the operating state of the sound pickup device, the LED lamp set is electrically connected with the sound pickup circuit board 32 or the sound pickup circuit board 31, and the LED lamp set is used for indicating the operating state of the sound pickup device.
When the sound picking device is used, an operator can control the working state of the sound picking device through a remote controller, a control button on an interactive display screen or a mobile phone; the audio control board 32 receives a control signal sent by an operator and controls the working state of the sound pickup device, and meanwhile, the audio control board 32 controls whether the LED lamp bank emits light or not through the sound pickup circuit board 31, or the audio control board 32 directly controls whether the LED lamp bank emits light or not, so that the working state of the sound pickup device is indicated through the LED lamp bank.
Specifically, if the pickup device is in a mute state, the LED lamp group emits light of a first color; otherwise, if the sound pickup device is in a sound pickup state, the LED lamp group is turned off or emits light of a second color. Wherein the color of the first color light is different from the color of the second color light, for example: the first color light is red and the second color light is green.
An operator can judge the specific working state (mute state or pickup state) of the pickup device according to the light on the LED lamp group, so that when pickup is not needed, the operator can adjust the working state of the pickup device from the pickup state to the mute state in time; the pickup device is prevented from occupying the memory of the interactive display large screen when being in a pickup state for a long time, and the smoothness of the system when the interactive display large screen is used is ensured.
Referring to fig. 5 and 6, in a specific embodiment, the LED lamp set includes a lamp panel 23 and at least one LED lamp 24 disposed on the lamp panel; the interactive large display screen further comprises a lamp panel fixing seat 2, the lamp panel 23 is installed on the lamp panel fixing seat 2, the lamp panel fixing seat 2 comprises a panel part 29, the panel part 29 forms a first light diffusion plate 21, the LED lamp group is located on the rear side of the panel part 29, and light emitted by the LED lamp group faces towards the panel part 29.
When operating personnel was operating the mutual display large screen, operating personnel can direct observation mutual display large screen's display surface and panel portion 29, and the light that the LED banks sent shines to panel portion 29, and this light is observed to operating personnel accessible panel portion 29 to judge pickup attachment's operating condition.
Panel portion 29 constitutes first light diffuser plate 21, the light that the LED banks sent shines behind first light diffuser plate 21, first light diffuser plate 21 can cause great interference to light, light passes through behind first light diffuser plate 21, can form the great facula 213 of an area at panel portion 29's leading flank, the light of this facula 213 reaches operating personnel's eye more softly, and then, operating personnel is when using mutual display large screen, panel portion 29 leading flank facula 213's light can not cause the interference to operating personnel's sight.
Referring to fig. 7, further, the panel portion 29 includes a light-transmitting portion 212 and a non-light-transmitting portion 211, and the non-light-transmitting portion 211 is provided with a black light-shielding layer on a side of the panel portion 29 away from the LED lamp set.
Light emitted from the LED lamp set can only be emitted from the light-transmitting portion 212; under the condition that the LED lamp group is lighted, an operator needs to know the working state of the sound pickup device, and the operator can only see the light spots of the light transmission part 212, so that the light transmission part 212 can be designed in a regular shape (such as a strip shape, a round shape and the like), and the indication light spots (the patterns formed by the superposition of the light spots on the front side surface and the light transmission part) seen by the operator are more attractive.
The light shielding layer is located on the panel portion 29 on the side away from the LED lamp group, and the light shielding layer is attached to the front side surface of the panel portion 29. The light emitted by the LED lamp group passes through the first light diffusion plate 21, and the first light diffusion plate 21 can cause the light to generate an interference phenomenon, so that if the light shielding layer is located at the rear side of the panel portion 29, the light passes through the white part (corresponding to the light transmission part) between the light shielding layers, and the light interferes in the first light diffusion plate 21, so that the indication light spot which can be seen by an operator formed on the front side surface of the panel portion 29 is larger than the light transmission part, and the boundary of the indication light spot is fuzzy; in the present invention, the light shielding layer is provided on the front side surface of the panel portion 29, the shape of the formed indication light spot is the shape of the light transmitting portion (the light spot formed on the front side surface completely covers the light transmitting portion), the boundary of the indication light spot is clear, and the operator can easily recognize the indication light spot.
In addition, the color of the non-light-transmitting part 211 can be black, so that the indication light spot (the color is red) is obviously distinguished from the non-light-transmitting part 211, and the working state of the sound pickup device can be easily distinguished by an operator.
The light shielding layer can be formed by spraying black powder on the front side surface of the panel portion 29, the black powder completely covers the front side surface of the panel portion 29, and then laser-engraving the light-transmitting portion on the front side surface of the panel portion 29; or the light shielding layer is silk-screened on the front side surface of the panel part 29 by a silk-screening method.
In addition, pickup attachment is in under the mute state, and the LED banks sends red light, and pickup attachment is in the pickup state, and the LED banks is closed (does not send light). When the LED lamp group is turned off, the space where the LED lamp group is located is a closed space, and there is no light inside, so that when the operator views the panel portion 29 from the outside, the entire panel portion 29 is black (both the light-transmitting portion 212 and the non-light-transmitting portion 211 are black). And enhancing the grade of the interactive display large screen.
In a specific embodiment, the lamp panel fixing base 2 further includes a blocking rib, and the blocking rib forms a second light diffusion plate 22; in the front-rear direction, the rib is located between the panel portion 29 and the LED lamp group, and a first space 27 is provided between the rib and the panel portion 29.
