Under the strong drive of the new four modernizations of the vehicle towards "electrification, intelligence, networking, and sharing", the intelligent cockpit, as the carrier of the interaction between people and vehicles, especially in the application of perception, prediction, information exchange, etc., has effectively improved the penetration rate of the display screen in the vehicle display.

The popularization of multi-screen in one chip, multi-screen mutual touch, three-dimensional virtual presentation and other technologies brought by the highly intelligent era is the foundation of the development of intelligent cockpit, which can display more information, better ensure driving safety, and provide a more comfortable driving environment, so as to realize the all-round intelligent interaction of people, vehicles and roads.

Consumer Femand for Driving

Vehicle driving safety is the most basic demand of car using, and the intelligent cockpit is moving towards the development direction of the new four modernizations application, providing a variety of use scenarios for passengers, such as mobile video conferencing for business people, social interaction and video entertainment with family and friends.

The intelligent development of automobiles is regarded as a mobile home by many consumers, who pursue more convenient driving methods and more comfortable driving environment. 

Poor Light Performance

The color and intensity of the headlights from various types of cars on the two-way driving road are different, especially the misuse of high beams will cause serious visual distress to pedestrians and drivers, which is a common factor causing traffic accidents.

Interior Backlighting

Driving at night requires higher attention. If the luminance and chrominance of the vehicle backlight key, dashboard, display and atmosphere light are deviated, it will more or less interfere with the driver's view to divert attention, and increase the insecurity of night driving.


RayClouds' representative imaging colorimeter is a good solution to the needs of high-quality vision for vehicle displays, ensuring the quality display performance of luminance, chrominance, uniformity, contrast, resolution, color gamut and so on.  

RayClouds' series of imaging photometer and colorimeter are equipped with sensitive sensors, cooperating with the ProICM professional analysis software independently developed by the RayCloud team to detect various optical parameters of the two-dimensional imaging screen, which completes the data analysis of the measured parameters in a quick, comprehensive and efficient way, providing solutions to optimize the imaging quality of displays and improving the production efficiency.

While attracting consumers, high-definition and delicate imaging quality is also a key layout area for auto companies to seek differentiation and brand development in the display industry.  

Exterior Lighting

Headlights: high beams, near beams, front turn signals, side turn signals, front fog lights, brake lights and daytime running lights.  
Rear lights: high brake lights, brake lights, rear turn signals, reversing lights, rear fog lights, driving indicators and license plate lights. 
Rapid test of light intensity distribution

Measure the chroma, color coordinates, uniformity and difference of the left headlight, etc.

Interior Backlighting

Multimedia display, backlit key, car ceiling light, dashboard, atmosphere light,makeup light, door light and suitcase light.  
Automatic identification of luminous characters

Clear data report

The ProICM software function could intelligently identify the high luminance range and grab the highlighted areas to accurately measure a series of optical parameters such as luminance and chrominance.

Atmosphere light is to show the personality, its design should take into account the safety and comfort uniformity, etc., reflecting the unique charm of the atmosphere light from many aspects, so whether its optical parameters are within the qualified range is important.  

The luminance, chrominance and uniformity of interior lights are generally measured by using an imaging colorimeter. 
ROI measurement: optical characteristics such as luminance, chrominance, color temperature, uniformity and so on

Four Steps to Customizing Measurement Solutions

Consultation: If there is a research demand for new product optical measurement, a free optical measurement technology solution is provided according to the requirements of the development project. 
Design: Accurate research suggestions on optical indicators are given for the vehicle lighting, display, backlight and other optical devices to guide the establishment of reasonable development and design standards.   
Testing: Perform optical tests for the light environment outside the car.  
Evaluation: Accurate and quantitative evaluation of optical design is carried out to verify the rationality of optical design and guide the product optimization.  

With a more perfect measurement solution, we promote the development of intelligent cockpit’s innovation chain, industrial chain and value chain, and help to achieve a more perfect large-scale application of human-vehicle interaction.
