To traditional on-vehicle jumbo size section sign indicating number LCD instrument in the current industry, or LCD directly exposes, or paste glass apron 10 at LCD surface frame, can not satisfy the problem of customer to the integrative black outward appearance effect of instrument display screen 20 and the high definition information display demand, the section sign indicating number LCD instrument that this embodiment provided, glue 60 full laminating through optics between glass apron 10 and section sign indicating number LCD screen 20, reflectivity is reduced, realize the integrative black outward appearance effect of instrument display screen 20 and high definition information display.
To traditional on-vehicle jumbo size section sign indicating number LCD instrument in current industry, LCD is direct naked, or pastes glass apron 10 at LCD surface frame, and antistatic properties is general, is difficult to reach antistatic standard, and the section sign indicating number LCD instrument that this embodiment provided has plated electrostatic shield 70 in the one side that glass apron 10 is towards section sign indicating number LCD screen 20.
In the antistatic structure, the middle position of the glass cover plate 10 is a light-transmitting window area 11, and the peripheral positions are light-shielding ink areas 12; an FPC (flexible printed circuit) flat cable 13 communicated with the electrostatic shielding layer 70 is arranged at the position, attached to the ink area 12, of the segment code LCD screen 20; the FPC bus 13 is connected to the PCBA40 and grounded.
Preferably, but not limited to, the electrostatic shielding layer 70 is an ITO electrostatic shielding layer 70.
The technical scheme provided by the embodiment not only reduces the reflectivity, but also realizes the integral black appearance effect and high-definition information display of the instrument display screen; the electrostatic shielding and releasing capacity is also improved, and the following standards can be met: contact discharge ± 8KV, CLASS a; air Discharge ± 20KV, CLASS B.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
