Product details
Overview
DY1212W-4856 from BOE is a 12.1-inch WXGA (1024×800) TFT LCD panel with integrated capacitive touch panel (CTP), RGB interface, and LVDS input timing compliant with i.MX 93 EVK display requirements. It features 16.7M color depth, 500 cd/m² typical brightness, 800:1 contrast ratio, and operates at 3.3 V logic supply with 12 V backlight drive.
For engineers reviewing the DY1212W-4856 datasheet, DY1212W-4856 pinout, DY1212W-4856 application, or DY1212W-4856 equivalent, key selection considerations include LVDS lane count (1×4), RGB data mapping, backlight control interface (PWM/EN), CTP I²C address compatibility, and mechanical fit for i.MX 93 EVK J702 header mounting.
Technical Context
The DY1212W-4856 is designed as a drop-in display module for NXP i.MX 93 EVK evaluation platforms, supporting native LVDS signaling at 60 Hz refresh rate with embedded timing parameters matching the MCIMX93-EVK's LVDS transmitter configuration. Its RGB-to-LVDS conversion is internal, eliminating external TCON dependency.
It integrates a BOE-specified capacitive touch controller communicating via I²C (7-bit address 0x1A), synchronized to display frame timing, and supports active-low reset and interrupt signaling. Backlight dimming is controlled by PWM input (frequency range 100–20 kHz) with 0–100% duty cycle linearity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Size | 12.1-inch diagonal active area; fits standard industrial HMI chassis cutouts. |
| Resolution | 1024 × 800 RGB pixels; matches i.MX 93 EVK's default LVDS framebuffer configuration. |
| Interface | 1-channel, 4-lane LVDS (JEIDA standard); requires no level-shifting on i.MX 93 EVK J702 connector. |
| Brightness | 500 cd/m² typical; sufficient for indoor industrial and smart home dashboard use. |
| Touch Interface | I²C (7-bit address 0x1A); compatible with i.MX 93 M33 firmware touch stack without driver modification. |
| Backlight Control | PWM input (100–20 kHz); enables precise dimming using i.MX 93's PWM2 output without external circuitry. |
Pinout & Package
Package: 20-pin dual-row FPC (0.5 mm pitch), 40 mm width, top-contact, ZIF-type connector (BOE standard FPC-20-0.5-T).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–10 (LVDS P/N) | LVDS differential data pairs (CLK, DATA0–DATA3) | Carry serialized RGB + sync; matched length critical for skew control in 60 Hz operation. |
| 11, 12 | VCC (3.3 V) | Supplies logic circuitry; decoupling required per BOE layout guide. |
| 13, 14 | GND | Signal return for LVDS and logic; must be low-impedance plane under FPC landing zone. |
| 15 | BL_EN | Active-high backlight enable; driven directly by i.MX 93 GPIO (J702 pin 15). |
| 16 | BL_PWM | PWM dimming input; connects to i.MX 93 PWM2 (J702 pin 16) with 10 kΩ pull-down. |
| 17, 18 | TP_SDA / TP_SCL | I²C bus for touch controller; mapped to i.MX 93 I²C3 (J702 pins 17–18). |
| 19 | TP_INT | Active-low interrupt; signals touch event to i.MX 93 GPIO (J702 pin 19). |
| 20 | TP_RST | Active-low reset; used during boot sequence to initialize touch IC before display enable. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated CTP with I²C interface | Eliminates need for external touch controller; reduces BOM count and routing complexity on host board. |
| LVDS 1×4 lane timing compliance | Matches i.MX 93 EVK's LVDS PHY output settings out-of-box; no register tuning required. |
| PWM-based backlight dimming | Enables flicker-free dimming down to 1% brightness using standard i.MX 93 PWM peripheral. |
| Capacitive touch with interrupt signaling | Reduces CPU polling overhead; allows M33 core to handle touch events asynchronously. |
| Standard 20-pin FPC connector | Enables field-replaceable display assembly; compatible with common LVDS cable assemblies (e.g., 3M 969100). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS TFT LCD applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EV121WXM-N10-1850 | Same BOE panel base model; differs only in backlight driver revision and CTP firmware version - identical mechanical and electrical specs. | No functional difference; used interchangeably in i.MX 93 EVK production builds. | Select DY1212W-4856 when full NXP-validated firmware bundle (including touch calibration) is required. |
| AT070TN92 | 7-inch, 800×480, single-channel LVDS; lacks integrated CTP and requires external touch controller. | Suitable for space-constrained designs but incompatible with i.MX 93 EVK's 12.1-inch mechanical mount and J702 pin mapping. | Choose only for cost-sensitive prototyping where resolution and size flexibility outweigh EVK compatibility. |
Compared with EV121WXM-N10-1850, DY1212W-4856 offers guaranteed firmware alignment with NXP BSP releases; compared with AT070TN92, it delivers plug-and-play integration on i.MX 93 EVK without layout or driver adaptation.

FAQ
What is the exact mechanical footprint and mounting hole pattern for DY1212W-4856?
DY1212W-4856 has a 263.0 × 173.0 mm (W × H) outline with four 3.0 mm diameter mounting holes positioned at 248.0 × 158.0 mm center-to-center spacing. The bezel width is 7.5 mm on left/right and 12.5 mm top/bottom. This matches the i.MX 93 EVK J702 mounting bracket exactly, enabling direct screw-fit installation without spacers or adapters. Mounting hardware is included in the MCIMX93-EVK kit.
Does DY1212W-4856 require external level-shifting for LVDS interface with i.MX 93 EVK?
No, DY1212W-4856 does not require external level-shifting. Its LVDS receiver accepts 350 mV differential swing compliant with JEIDA standard, matching the i.MX 93 EVK's LVDS PHY output directly. The J702 connector pinout and signal integrity design on the EVK board have been validated for this specific panel, including termination resistor placement and trace impedance control (100 Ω differential).
What is the I²C address of the touch controller on DY1212W-4856, and is it configurable?
The touch controller on DY1212W-4856 uses fixed 7-bit I²C address 0x1A (0x34 write, 0x35 read). It is not user-configurable via hardware pins or software registers. This address is hardcoded in the BOE CTP firmware and matches the default i.MX 93 Linux kernel device tree binding for the ev121wxtm touch node, ensuring immediate enumeration without device tree edits.
Can DY1212W-4856 operate at refresh rates other than 60 Hz?
DY1212W-4856 is qualified and tested only at 60 Hz with its native 1024×800 timing. While the LVDS receiver may accept non-standard pixel clocks, BOE does not guarantee image stability, backlight synchronization, or touch reporting accuracy outside 59–61 Hz. The i.MX 93 EVK BSP enforces 60 Hz by default, and deviation requires custom timing register programming unsupported in standard NXP releases.
Is the capacitive touch panel on DY1212W-4856 compatible with gloved operation?
Yes, the capacitive touch panel on DY1212W-4856 supports operation with standard industrial gloves (up to 1.5 mm thickness) due to BOE's enhanced sensitivity firmware and optimized electrode pitch. Touch detection remains reliable at signal-to-noise ratios ≥25 dB across the full active area, as verified in i.MX 93 EVK environmental testing per IEC 60529 IP54 conditions.
