Customized Automotive Display And Touch Solutions

Drivers expect their car displays to be intuitive, provide fast feedback, display clear and rich content, and be interconnected with mobile devices. However, meeting these requirements while also complying with the stringent automotive environment demands a comprehensive integration of technologies. During the manufacturing process, Xinhongtai Technology's display designers and technical engineers comprehensively consider factors such as the display's operating temperature, shock resistance, waterproofing, and the need for customized touch functionality, providing tailored solutions for different vehicle application scenarios.

Application of display screens in automobiles and four-wheel electric vehicles

Parameter requirements for automobile and four-wheel electric vehicle display screens:

1、High and low temperature resistant.

Since vehicles may be driven in different seasons and at different latitudes, in-vehicle displays must be able to operate normally within a wide temperature range. Therefore, temperature resistance is a fundamental quality. The current industry requirement is that the display screen must be able to withstand temperatures ranging from -40°C to 85°C.

2、Wide viewing angle.

The center console display screen should be visible to the driver and passengers (including those in the back seat).

3、High Dynamic Range (HDR).

Picture quality requires a comprehensive balance, particularly focusing on the realism and harmony of the image. This concept is known as HDR (High Dynamic Range). Its practical effect is that bright areas become brighter, while dark areas become darker, allowing for excellent display of details in both bright and dark areas.

4、Fast response time and refresh rate.

Smart cars, especially autonomous vehicles, need to collect road information in real time and provide timely alerts to drivers at critical moments. Rapid response and refresh rates prevent information lags and are crucial for warning indicators and navigation features such as real-time maps, traffic updates, and backup cameras.

5、Long service life.

In simple terms, automotive displays must support a design and production cycle of at least five years, which should be extended to 10 years due to vehicle warranties. Ultimately, the display's service life should be at least as long as the vehicle's.

6、High brightness.

It is crucial that the driver can easily read the information on the display in varying ambient light conditions, from bright sunlight to complete darkness.

7、High Resolution.

High resolution means that there are more pixels per unit area, and the overall picture is clearer.

8、High Contrast.

Contrast ratio is defined as the ratio of maximum brightness (full white) to minimum brightness (full black). Generally speaking, the minimum contrast ratio acceptable to the human eye is about 250:1. A high contrast ratio is beneficial for seeing the display clearly in bright light.

9、Wide color gamut.

High-resolution displays may need to upgrade from 18-bit red, green, and blue (RGB) to 24-bit RGB to achieve a wider color gamut. A wide color gamut is a very important indicator for improving display quality.

10、Anti-glare and reduced reflections.

In-vehicle displays provide critical vehicle information to drivers, and their visibility must not be reduced by ambient light conditions (especially during daytime sunlight). Of course, the anti-glare coating on their surface must not hinder visibility ("flicker" interference must be eliminated).

11、EMI

Anti-electromagnetic interference requires EMC performance to resist electromagnetic interference.

Application

Depending on the placement, the types of display screens in cars are divided into central control display screen, LCD instrument panel, head-up display, co-pilot and rear seat entertainment screen, side view screen, rearview mirror screen, etc.

LCD Instrument Cluster

A dashboard is an essential part of a car's display screen, capable of displaying the car's status to the driver, including information such as mileage, RPM, fuel consumption, door status, and seatbelt status. Every car has this type of display because drivers must clearly understand the car's status for safe and smooth driving. A car's dashboard only requires simple display functionality.

Application of display screens in E-Bike two-wheeled electric vehicles and motorcycles

For E-Bikes (smart electric bicycles/electric-assisted bicycles), users often require displays that provide essential riding data, power assist mode display, cadence, output power (wattage), calorie consumption, riding time, and other auxiliary information. Additionally, they require navigation, connectivity, vehicle status, and diagnostics to facilitate interaction between rider and vehicle. In contrast, for electric motorcycles/high-performance motorcycles, users prioritize high visibility, integration, and safety. Different riding requirements determine the performance level of the display. The following summarizes key parameters to consider when selecting displays for E-Bikes and electric motorcycles.

Display parameter requirements

Questions and answers from customers:

Question 1: If the monitor is placed at the car's air vent, how can I deal with water droplets from the air conditioner? How can I solve this problem?

Answer: The display itself is waterproof. To prevent water droplets from affecting the operation of the display, the waterproof function of the cable should be considered. When connecting the display to the control panel, the customer is required to take waterproof measures on the cable and other contact interfaces, such as applying silicone waterproofing method, etc.

Question 2: How to eliminate static electricity on car displays?

Answer: Every Hot Display product undergoes an electrostatic test before leaving the factory to minimize the risk of the display being "charged" before leaving the warehouse!

Question 3: Is it better to have the touchpad of the car display frame-laminated or fully laminated?

Answer: Full lamination is preferred for automotive displays. Full lamination is recommended for most touchscreen displays, as it offers excellent stability and minimizes rework. While many competitors outsource the lamination process to other companies, Hot Display has its own lamination team, capable of independently and comprehensively completing the entire production process.

Question 4: What kind of testing do you do before shipping?

Answer: Every display screen shipped from Xinhongtai undergoes electrostatic discharge (ESD) testing, group pulse EFT testing, vibration testing, high and low temperature impact testing, product aging testing, and tensile testing.

Question 5:What is the applicable temperature for car displays?

A: Because cars must withstand extreme outdoor weather, Hot Display, a manufacturer specializing in industrial-grade displays, can customize the temperature of our displays to meet customer needs. We can also offer wide-temperature options, with a maximum temperature range of -40°C to 80°C. The applicable temperature inside a car is generally -10°C (in winter) to 70°C (in summer), so Hot Display's displays are fully compatible with a wide range of vehicles.
