Car Monitor seems to be lighter and thinner in the tide of upgrade

Facing the trend of large-screen and multi-screen displays in cars, consumers have improved the technology and aesthetics of vehicle interiors, The thinness, and design of the LCD screen directly affect the interior atmosphere and become a major consideration for consumers when buying cars.

In addition, the increase of human-computer interaction information will increase the display area and interactive touch operation area, which will increase the cost of vehicle display and touch and the weight of the vehicle body. An automobile supply chain person said: "Whether it is the main engine manufacturer or a module manufacturer, it is gradually changing from the previous OGS and On Cell panels to In Cell panels, because of the light and thin demand for display products."

The vehicle-mounted Monitor products can reduce body weight and improve the energy efficiency ratio; At the same time, Light and thin narrow frames and high screen proportions are also the mainstream design style of automobile interiors at this stage.CINNO Research observed that in recent years, in order to meet the requirements of high definition, high contrast, low power consumption, low reflectivity, and touch/display function integration of on-board display, TFT-LCD In Cell display technology has gradually increased in the field of Car Monitor.

Just like the development of mobile phone display panel technology, the same is true for onboard displays. Both On Cell and In Cell integrate the touch layer and display panel, which can further reduce the overall thickness of the screen and make it thinner. The OCA only needs to appear once, which is used to paste the protective glass and the two-layer structure of the "touch display layer". The normal operation of the touch function is ensured by adding a separate touch circuit to the display layer.

The biggest difference between On Cell and In Cell lies in whether the touch unit/module is above or below the "CF (filter)". The touch layer designed by On Cell is placed outside the CF glass of the display panel, and there is a layer of color filter substrate between it and the LCD pixels. Unlike In-Cell technology, the touch unit is embedded into the LCD layer. On Cell requires a separate display driver chip and touch driver chip, while In Cell can use a TDDI chip to achieve both display driver and touch driver

In short, the technology of In Cell screen is the most complex, but the color balance of the display effect is better. Because the touch layer and air layer are reduced, a more consistent look can be obtained in the off-screen state.

" TFT-LCD In Cell display can reduce the number of panel layers and corresponding materials, and reduce certain costs. On the premise that the technology is gradually maturing, In Cell screens are gradually gaining popularity in the vehicle-mounted display market. They can not only meet the design requirements of narrow borders and thin thickness, but also have a lower reflectivity, which enables the screen to have an integrated look when it is turned off in the daytime, and to a certain extent, improves the display contrast. "a display technician explained the advantages of the In-Cell screen.
