Abstract

The invention discloses an instrument membrane, comprising a membrane body. The membrane body is a black translucent membrane made of a polycarbonate material and has transparency of 1% to 99%; two side surfaces of the membrane body are a frosted surface and a matte surface, respectively; the frosted surface has a thickness of 0.2 [mu]m to 2.0 [mu]m; and the matte surface has a thickness of 0.1 [mu]m to 1.8 [mu]m. The invention also provides a vehicle instrument. The vehicle instrument comprises the instrument membrane described above and a digital screen, wherein the instrument membrane is mounted in front of the digital screen. The instrument membrane of the invention is good in light permeability and uniform in light transmission; and when the instrument membrane is applied to the vehicle instrument, vehicle data on the digital screen can be read through the instrument membrane without the perception of graininess and impurities.

Description

technical field [0001] The invention relates to the technical field of vehicle instruments, in particular to an instrument film and a vehicle instrument. Background technique [0002] The vehicle instrument is an important part of the vehicle. There is a digital display in the instrument, which is used to display various parameters of the vehicle, such as vehicle speed, engine speed, fuel volume, indicator lights, etc. In the prior art, in order to enhance the display effect, a transparent film or a translucent film is installed in front of the digital display screen, and the driver reads various parameters on the display screen through the film. However, the film of the prior art has uneven light transmission, and the driver has obvious graininess when reading the parameters on the display screen through the film. Contents of the invention [0003] In view of this, in order to solve the problem that the film in the prior art has uneven light transmission, and the driver ...
