After purchasing an outdoor advertising machine, some customers may have some problems, large and small, if the problem is not big, we can solve it by ourselves. The following editor will introduce a few of them to let everyone understand what they are. The reason, so that everyone can better solve it, let's take a look.
Máquina de publicidade ao ar livre
A temperatura externa está em torno de zero, por que a tela aparece preta?
First of all, let's understand why the LCD screen will be black. Since the liquid crystal screen is composed of liquid and crystalline state, when the temperature exceeds 68 degree , the crystalline state will be transformed into a liquid state, causing display problems (ie, black screen). So why does the temperature go to a black screen when the temperature is around 0 degree ? Since the sun shines directly on the LCD screen at noon, and the liquid crystal molecules are very easy to absorb heat, the temperature of the LCD panel rises, which exceeds the maximum temperature and a black screen appears. According to this problem, this problem should be considered in equipment design. Although the ambient temperature is not too high, the fan still needs to be started and the speed can be reduced. The heat dissipation in front of the screen cannot be ignored.
2. Com filtro, por que ainda há poeira no equipamento?
O player de publicidade refrigerado a ar-é refrigerado a ar-, portanto, há fluxo de ar dentro e fora do dispositivo. Use um filtro de-camada dupla para impedir a entrada de pequenos insetos e grandes partículas de poeira. O filtro precisa ser limpo durante a operação normal do equipamento por um período de tempo. O intervalo de limpeza depende da qualidade ambiental local, como 6 meses, 8 meses ou 1 ano.
Embora o filtro filtre a poeira, partículas extremamente finas ainda podem entrar no equipamento. Se você não deseja obter nenhuma poeira, pode usar apenas o esquema de resfriamento de ar-condicionado.
3. A beleza da máquina de publicidade externa é importante? Ou a qualidade estável é importante?
Em alguns projetos anteriores, alguns clientes nos pediram para alterar a dissipação de calor interna, materiais, etc. devido a exigências excessivas de estética. Estética melhorada, menor estabilidade e incerteza, este método é um tanto preocupante.
