When comparing readability under direct midday sunlight, LCDs are generally more reliable. Because they rely on a dedicated backlight, it is easier to achieve higher peak brightness; consequently, elements like navigation maps or menus with white backgrounds are less likely to appear washed out or gray. OLEDs, by contrast, truly shine in low-light environments, such as at night or inside an underground parking garage.

I. Three Key Factors Determining Readability in Bright Light

Peak Brightness: The backlight structure of an LCD allows for a higher maximum brightness, ensuring that navigation interfaces with white backgrounds remain clear even under direct midday sun. OLEDs, however, experience increased power consumption when displaying high-brightness content, which limits their peak brightness potential.

Screen Reflection: Vehicle interiors are filled with ambient light. Even if an OLED display can render pixels as "true black," the screen surface will still reflect light from outside the vehicle. The stronger the ambient light, the less benefit there is to achieving deeper black levels.

Focus on White-Background Content: In daily driving, the primary use cases—navigation, traffic updates, and vehicle controls—typically involve interfaces with white backgrounds and bright elements. In these scenarios, what matters is sustained brightness and text clarity, not the depth of the black levels.

II. OLED’s Strengths: Best in Low-Light Conditions

True Black and Contrast: Since OLED pixels are self-emissive, they turn off completely when displaying black. This enables contrast ratios as high as 200,000:1, resulting in a more vivid, clear appearance for dark-themed UIs and low-light imagery.

Noticeable Differences Across Scenarios: While the distinction between the two technologies may be subtle during a daytime commute, the difference becomes immediately apparent when viewing navigation maps or video content at night or in an underground parking garage.China Digital Display

Motion and Viewing Angles: OLEDs feature microsecond-level response times, which minimize motion blur when quickly scrolling through maps or playing dynamic video. Furthermore, they offer more consistent color and brightness even when viewed from an angle—such as by a passenger in the front seat. III. Measured Specifications for Specific Models

Matching Specifications: The 29-inch 6K LCD screen currently installed in the Li Auto MEGA—the same unit used in the Li L9—offers the same 6K panoramic resolution as the original factory-fitted OLED display. The software, user interface, and OTA (over-the-air) update experience remain identical.

Capable Performance: This LCD panel is quite robust, featuring a 90Hz refresh rate, 180Hz touch sampling rate, 1,000 nits of brightness, and full DC dimming for flicker-free viewing. Following hands-on testing in bright daylight, some content creators have noted that the screen’s performance is excellent.

Future Replacement Option: Supplies of the Samsung OLED panels are expected to resume by the end of the year. Starting March 1, 2027, owners will be eligible for a free, non-destructive replacement back to the original factory OLED display, processed in the order of vehicle delivery. The replacement procedure takes approximately 12 minutes.
