}

Consumer-facing display capability model produced by a display data parser.

All fields defined by the relevant specification are decoded and exposed here. No field is omitted because it appears obscure or unlikely to be needed — that judgement belongs to the consumer, not the library.

Fields are Option where the underlying data may be absent or undecodable. None means the value was not present or could not be reliably determined; it does not imply the field is unimportant. The library never invents or defaults data.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

manufacturer: Option<ManufacturerId>

Three-character PNP manufacturer ID (e.g. GSM for LG, SAM for Samsung).

manufacture_date: Option<ManufactureDate>

Manufacture date or model year.

edid_version: Option<EdidVersion>

EDID specification version and revision.

product_code: Option<u16>

Manufacturer-assigned product code.

serial_number: Option<u32>

serial_number_string: Option<MonitorString>

Serial number string from the monitor serial number descriptor (0xFF), if present.

display_name: Option<MonitorString>

Human-readable display name from the monitor name descriptor, if present.

unspecified_text: [Option<MonitorString>; 4]

Unspecified ASCII text strings from 0xFE descriptors, in descriptor slot order.

Up to four entries (one per descriptor slot). Each slot is None if the corresponding descriptor was not a 0xFE entry.

white_points: [Option<WhitePoint>; 2]

Additional white points from the 0xFB descriptor.

Up to two entries (the EDID 0xFB descriptor has two fixed slots). Each slot is None if the corresponding entry was unused (index byte 0x00).

digital: bool

true if the display uses a digital input interface.

color_bit_depth: Option<ColorBitDepth>

Color bit depth per primary channel. None for analog displays or when the field is undefined or reserved.

display_technology: Option<DisplayTechnology>

Physical display technology (e.g. TFT, OLED, PDP). None when the Display Device Data Block is absent.

display_subtype: Option<u8>

Technology-specific sub-type code (raw, 0–15). None when the Display Device Data Block is absent.

operating_mode: Option<OperatingMode>

Panel operating mode (continuous or non-continuous refresh). None when the Display Device Data Block is absent.

backlight_type: Option<BacklightType>

Backlight type. None when the Display Device Data Block is absent.

data_enable_used: Option<bool>

Whether the panel uses a Data Enable (DE) signal. None when the Display Device Data Block is absent.

data_enable_positive: Option<bool>

Data Enable signal polarity: true = positive, false = negative. Valid only when data_enable_used is Some(true). None when the Display Device Data Block is absent.

native_pixels: Option<(u16, u16)>

Native pixel format (width_px, height_px). None when the Display Device Data Block is absent or either dimension is zero.

panel_aspect_ratio_100: Option<u8>

Panel aspect ratio encoded as (AR − 1) × 100 (raw byte). For example 77 represents approximately 16:9 (AR ≈ 1.77). None when the block is absent.

physical_orientation: Option<PhysicalOrientation>

Physical mounting orientation of the panel. None when the Display Device Data Block is absent.

rotation_capability: Option<RotationCapability>

Panel rotation capability. None when the Display Device Data Block is absent.

zero_pixel_location: Option<ZeroPixelLocation>

Location of the zero (origin) pixel in the framebuffer. None when the Display Device Data Block is absent.

scan_direction: Option<ScanDirection>

Fast-scan direction relative to H-sync. None when the Display Device Data Block is absent.

subpixel_layout: Option<SubpixelLayout>

Sub-pixel color filter arrangement. None when the Display Device Data Block is absent.

pixel_pitch_hundredths_mm: Option<(u8, u8)>

Pixel pitch (horizontal_hundredths_mm, vertical_hundredths_mm) in 0.01 mm units. None when the Display Device Data Block is absent or either pitch is zero.

pixel_response_time_ms: Option<u8>

Pixel response time in milliseconds. None when the Display Device Data Block is absent or the value is zero.

power_sequencing: Option<PowerSequencing>

Interface power sequencing timing parameters. None when the Interface Power Sequencing Block is absent.

transfer_characteristic: Option<DisplayIdTransferCharacteristic>

Display luminance transfer function. None when the Transfer Characteristics Block is absent.

display_id_interface: Option<DisplayIdInterface>

stereo_interface: Option<DisplayIdStereoInterface>

Stereo display interface parameters. None when the Stereo Display Interface Data Block is absent.

tiled_topology: Option<DisplayIdTiledTopology>

Tiled display topology. None when the Tiled Display Topology Data Block is absent.

chromaticity: Chromaticity

CIE xy chromaticity coordinates for the color primaries and white point.

gamma: Option<DisplayGamma>

Display gamma. None if the display did not specify a gamma value.

display_features: Option<DisplayFeatureFlags>

Display feature support flags.

digital_color_encoding: Option<DigitalColorEncoding>

Supported color encoding formats. Only populated for EDID 1.4+ digital displays.

analog_color_type: Option<AnalogColorType>

Color type for analog displays; None for the undefined value (0b11).

video_interface: Option<VideoInterface>

Video interface type. None for analog displays or when the field is undefined or reserved.

analog_sync_level: Option<AnalogSyncLevel>

Analog sync and video white levels. Only populated for analog displays.

screen_size: Option<ScreenSize>

preferred_image_size_mm: Option<(u16, u16)>

More precise than screen_size (which is in cm). None when all DTD image-size fields are zero.

timing_formula: Option<TimingFormula>

Video timing formula reported in the display range limits descriptor.

color_management: Option<ColorManagementData>

DCM polynomial coefficients.

supported_modes: Vec<VideoMode>

Video modes decoded from the display data.

warnings: Vec<ParseWarning>

Non-fatal conditions collected from the parser and all handlers.

Not serialized — use a custom handler to map warnings to a serializable form.

extension_data: Vec<(u8, Arc<dyn ExtensionData>)>

Typed data attached by extension handlers, keyed by extension tag byte.

Uses a Vec of (tag, data) pairs rather than a HashMap so that this field is available in alloc-only (no_std) builds. The number of distinct extension tags in any real EDID is small enough that linear scan is negligible.

Not serialized — use a custom handler to map this to a serializable form.
