What is the multi mode feature and what are its scenarios?
Multi-mode refers to the capability of a receiving card to support multiple display modes. This is suitable for scenarios where the same batch of cabinets needs to be used in different requirements. Previously, to achieve this, multiple sets of rcfgx files had to be prepared in advance, switched different files which matched for different scenarios. Now, before producing the NCP, engineers collect the user’s scenarios in advance, involving different receiving card and chip parameters. Different modes are provided for switching based on different scenarios. Users can easily switch between display modes according to different usage scenarios, allowing the LED screen to display effects configured with different parameters.
Scenarios:
- Common indoor/outdoor modes: Indoor and outdoor scenarios have different brightness requirements. While adjusting brightness rod in VMP can achieve the target but will reduce grayscale and refresh rate. The method of reducing Current Gain can achieve the desired brightness while minimizing grayscale loss, providing better display quality.
- xR/VP shooting modes: On-site, different display modes can be switched based on the content being shot. The shooting mode effect significantly improves the shooting effect of low-brightness source by greatly enhancing the low-gray refresh rate of the chips, reducing scan line issues in low-gray shooting scenarios.
What are the differences between Adaptive Frame Rate 1.0/2.0/3.0, and what are their scenarios?
V1.0: A single fixed frame rate, typically 60Hz. The performance is consistent with NovaLCT, and there is only one parameter set. (Selectable fixed rates: 24Hz, 25Hz, 30Hz, 48Hz, 50Hz, 60Hz, 100Hz, up to 120Hz). Switching to other frame rates may cause screen flickering or blackout. This function is suitable for most common usage scenarios.
V2.0: Multiple fixed frame rates (e.g., 24Hz, 25Hz, 30Hz, 48Hz, 50Hz, 60Hz, 100Hz, 120Hz, up to 240Hz). Supports independent image booster files for the above fixed frame rates. It ensures normal display when switching between these specified frame rates, but other frame rates may result to abnormal display. This function is suitable for certain rental and broadcasting scenarios.
V3.0: Multiple frame rate bands (e.g., 23-60Hz, 61-120Hz, 121-240Hz). Guarantees normal display when switching to any frame rate within the supported frame rates range, with 0.01Hz increments. This function is suitable for virtual production.
What technologies does the Image Booster include? What is the value of each?
NovaStar launched a high image quality solution fine pitch LED screens- Image boost engine. Including 22 Bit+, Precise Grayscale, and Color Management, it can restore the real world colors, making small-pitch LED screens to satisfy the requirements for high-end display from different dimensions.
22bit+ is a gray-scale coding technology developed by Novastar that combines the visual characteristics of the human eye. This technology combines the characteristics of the human eye with the new gray-scale coding design,which increases grayscale levels by 64 times.It effectively deal with the loss of low-brightness grayscale, makes it smoother, and bring better details to the image.
Precise grayscale technology implements level-by-level measurement on 16bits (65536 levels) grayscale of the driver IC.By utilizing the software algorithm, it can achieve level-by-level calibration, bring smoother transitions, improve quality on the low-grayscale display.
Color management can achieve effective control of the color of the display screen, using certain algorithm logic, and the combination of software and hardware to automatically and uniformly manage and adjust the color to ensure the display effect of the same color gamut of the image, showing the consistency of the color and the color. accuracy. Color management can accurately manage the intersection of the color gamut of the LED screen and the standard display color gamut to ensure that the color of the screen is consistent and solve the problem of color cast.
