A competitive high resolution, high luminance and wide viewing angle automotive display.

In the automotive world screens are increasingly replacing mechanical controls. The screen market should therefore continue to grow over the next few years.
However, we still do not know which providers will become long-term winners. To meet the demands of the market and its users, it is important to consider various conditions and specifications.
Display characteristics such as luminance, contrast ratio, grayscale and color continuously need to be improved. So too does the maintenance of these properties under automotive conditions characterized by variable temperatures and ambient light.

With the Medianav, LG Display provides drivers and passengers a human-machine interface.
Its advanced technology allows for high resolution, high luminance and wide viewing angle, which is the standard display in smart cars.

The LG Display’s Medianav offers these features at a competitive price, and supply it to a range of manufacturers. This cost-performance ratio is made possible by production in low-cost manufacturing countries and the experience LG Electronics has acquired in the automotive market.

This report presents a complete analysis of the dismantling of the LG Electronics screen and associated touch screen, taken from the latest Dacia Duster model. On this basis, it provides the bill of materials and manufacturing cost of the display module. The report also provides a complete physical analysis and manufacturing cost estimate for each part, including the backlight module, electronic boards and various mechanical frames.
