It is said that in a cool environment below -40°C, the response speed of LCD is about 10 times lower than that at a normal temperature.
Thus the measure against LCD responsiveness at low temperature is an important issue for the automobiles with cold wheather specification.
In order to solve this matter, Nissha is developing Transparent Film Heater which can be incorporated into LCD module.
Improve responsiveness
at low temp.
Film type to be incorporated
onto back light panel
One-stop solution
to laminate
and deliver with cover panel
Our heater is film type with around 100µm thickness.
Using a unique transparent conductive film with excellent heating efficiency.
Having the features such as high-speed heating, transparency and thin film.
The total light transmittance of our heater is 85%.
Because of its transparency and thinness, it can be incorporated into LCD module, such as between liquid crystal and backlight, and between touch panel and liquid crystal.
The temperature rises by about 40℃ in 60 seconds after the power is turned on.
In addition, the temperature distribution on the surface can be uniformed. (12V / normal temp. environment)
You can use it on a monitor like E-mirror display that protects the safety of drivers.
We support you from the product design stage. We will customize the design such as heater size & shape, wiring, and temperature control, according to the customer’s request.
Looking forward to your requests of heater sample and development project.
Please feel free to contact us.
Whether supplying the heater film alone or as part of the module including the laminated cover glass, touch sensor and LCD display Nissha can support. Our project and QA management experience for film touch sensor programs seamlessly extends to the inclusion of optically clear film heater from development through to mass production.
1．Check if it can be accepted
Review the technical difficulty of the customer’s required specifications.
While coordinating between the technical department and the sales department, information such as material design, process technology, and cost adequacy will be organized and it will be examined whether it can be entrusted.
2．Organize a project team for each project
If it is confirmed that the contract can be accepted, a project team will be formed for each project.
The team is made up of members selected from each of the technical development, design, production technology, evaluation technology, and quality assurance departments, and plans for mass production.
3．Validate your design with small-lot production prototypes
Verification of design validity through small lot prototypes.
We perform mass production suitability evaluation, failure mode analysis, reliability evaluation, etc., and confirm the optimal mass production conditions.
Prototype results will also be reported to customers, confirming that there is no problem even if they shift to mass production.
4．Mass production to delivery
After preparing the mass production transfer document based on the results of the prototype verification, the project is transferred to the mass production department and mass production is started.
5．Quality control of mass-produced products
After mass production, the quality assurance department manages whether stable production is running or whether there are no defective products outgoing. The quality assurance department joins the project from the design verification stage, enabling intrinsic quality assurance.
Please feel free to contact us for any questions or consultations on film devices, including consultation on development, trial production, mass production consignment, etc.
