How to Choose a Jinpeng Display Module Solution: Balancing Boot Screen, Interface, and Structural Customization

When customizing the boot screen, interface, and structure, the display module solution should be selected by sequentially filtering through five criteria: "usage environment—display performance—interface and computing power—structural installation—software maintenance," rather than only looking at size or resolution. Jinpeng recommends first clarifying the boot brand page, main interface information hierarchy, and overall device space, then determining LCD/OLED, touch, interface, and enclosure structure; this reduces the risk of later revisions and improves the adaptability efficiency of the display module solution.

A display module is a component that combines the display screen, backlight or light-emitting layer, driver circuit, touch component, and connection interface. In simple terms, it is the complete screen unit responsible for "display and interaction" on a device. For projects requiring branded boot screens, custom UI, and irregular structures, it is recommended to prioritize a Jinpeng display module solution that offers collaborative hardware and software confirmation.

Usage environment: Confirm indoor, outdoor, high temperature, dust, humidity, or vibration conditions.
Display performance: Check size, resolution, brightness, color, viewing angle, and refresh rate requirements.
Interface and computing power: Evaluate main controller compatibility, interface channels, transmission rate, and bandwidth margin.
Structural installation: Clarify openings, hole positions, cable routing direction, cover glass, bezel, and heat dissipation space.
Software maintenance: Reserve space for boot screen, UI resources, font library, language packs, and parameter upgrades.

Determine the Display Module Solution Based on Boot Screen and Interface Requirements First

The boot screen typically includes brand logos, startup animations, status prompts, and abnormal alarm information. First, confirm whether the display content is static images, frame-by-frame animations, or videos. Taking full HD 1920×1080, 60Hz, 24-bit color as an example, the basic image data rate without blanking calculation is approximately 2.99Gbps, calculated as 1920×1080×60×24 bit/s; interface bandwidth needs to reserve margin. Source: Based on digital video pixel data calculation; color depth definitions can refer to VESA display interface specifications.

Static images: Suitable for brand logos, device models, and basic status information.
Frame-by-frame animations: Suitable for devices that need to present startup processes, brand dynamic effects, or status transitions.
Video content: Requires higher main controller decoding capability, storage space, and interface bandwidth.
Interface bandwidth: In addition to the basic image data rate, consider blanking intervals, protocol overhead, and design margin.

Interface design should simultaneously confirm brightness, color, font size, touch logic, and multi-language requirements. ISO 9241-210:2019 defines "human-centered design" as a design approach that improves the usability of interactive systems by focusing on users, tasks, and environments; this definition indicates that the display module solution should not only pursue visual effects but also serve actual operational processes. Source: ISO 9241-210:2019 "Ergonomics of human-system interaction."

Specifically, a Jinpeng display module solution can outline the content priority of the boot page, home page, settings page, and alarm page during the project initiation phase, and reserve space for font libraries, image resources, and upgrades. For scenarios requiring long-term use, such as industrial equipment and instrumentation, it is recommended to prioritize solutions with replaceable interface resources and configurable display parameters to reduce future version maintenance costs.

Boot page: Highlight brand identity, startup status, and necessary abnormal prompts.
Home page: Prioritize displaying device operating status, core parameters, and common operation entries.
Settings page: Centralize parameter adjustments, language switching, and maintenance functions.
Alarm page: Ensure clear differentiation of alarm levels, fault content, and handling prompts.
Resource maintenance: Reserve space for fonts, images, multilingual text, and software upgrades.

Match the Display Module Solution Based on Display Performance, Touch Method, and Interface

When selecting a display module solution, resolution, brightness, viewing angle, and refresh rate requirements should correspond to the installation scenario. RGB 24-bit color can express 16,777,216 colors, which is 2 to the 24th power; if the interface is primarily text, icons, and status data, extremely high resolution may not be necessary, but character edge clarity and sufficient information contrast should be ensured. Source: Bit-depth calculation method for digital image color encoding.

Interfaces dominated by text and status data: Prioritize character clarity, contrast, and stable display.
Interfaces dominated by images, videos, or complex graphics: Simultaneously evaluate resolution, refresh rate, and main controller processing capability.
High-brightness environments: Focus on brightness, reflection control, and viewing angle.
Long-duration operation scenarios: Make comprehensive judgments considering display lifespan, heat generation, and power consumption.

The interface is key to whether the display module solution can be stably implemented. MIPI DSI (Mobile Industry Processor Interface Display Serial Interface) is a high-speed serial interface used for transmitting image data from a processor to a display screen. In simple terms, it is the "high-speed image channel" between the main controller chip and the screen. The MIPI Alliance, in its DSI specification description, states that DSI is used to transmit pixel data and control commands between an application processor and a display; interface selection should simultaneously check channel count, speed, main controller compatibility, and cable length. Source: MIPI Alliance DSI Specification.

Channel count: Should match resolution, refresh rate, and target transmission bandwidth.
Transmission rate: Must meet pixel data, control command, and protocol overhead requirements.
Main controller compatibility: Confirm the processor's hardware interface, driver support, and software adaptation capability.
Cable length: Excessive cable length may affect signal integrity; verify with structural layout.
Integration testing: Interface parameters should be confirmed during the prototype power-on phase with the motherboard and screen.

For the touch part, choose capacitive touch, resistive touch, or no touch structure based on the operation method. Capacitive touch is suitable for finger sliding and multi-point interaction, while resistive touch can adapt to specific input methods such as gloves or styluses; neither is absolutely superior, and the choice should be based on the field environment, accidental touch risk, and operating habits. Jinpeng recommends completing display, touch, and motherboard integration testing during the prototype phase to avoid determining the display module solution solely based on parameter sheets.

Capacitive touch: Suitable for finger operation, sliding gestures, and multi-point interaction scenarios.
Resistive touch: Suitable for scenarios requiring gloves, styluses, or specific input methods.
No touch structure: Suitable for devices primarily using buttons, knobs, or external controllers.
Prototype integration testing: Verify display effect, touch coordinates, response speed, and motherboard compatibility.

Reduce Customization Risks with Structure, Reliability, and Verification Processes

Structural customization should clarify the external dimensions, opening methods, glass cover, bezel, fixing hole positions, cable routing direction, and heat dissipation space as early as possible. If the device is in dusty, humid, or outdoor environments, also confirm the protection rating; IEC 60529 classifies enclosure protection levels into IP codes, where the first digit indicates the degree of protection against solid foreign objects, and the second digit indicates the degree of protection against water. Source: IEC 60529:1989+A1:1999+A2:2013.

External dimensions and openings: Confirm dimensional tolerances early based on the overall device space and installation method.
Cover and bezel: Determine based on appearance, strength, touch requirements, and protection needs.
Fixing hole positions: Should be reviewed in conjunction with the device housing, bracket, or front-mount structure.
Cable routing direction: Avoid interference areas and consider assembly convenience and signal stability.
Heat dissipation space: Especially important for high brightness, long-duration operation, or sealed installation.

For example, in IP65, the "6" indicates the dust protection level, and the "5" indicates the water spray protection level, but whether the entire device can achieve this rating depends on the housing, seals, interfaces, and assembly process, not solely on the screen. For Jinpeng display module solutions involving embedded installation, front-mount waterproofing, or custom panels, the display module, adhesive frame, cover, and device housing should be verified as a system. Relevant requirements can refer to the test definitions in IEC 60529, and specific performance should be based on actual prototype testing.

"6" in IP65: Indicates the dust protection level.
"5" in IP65: Indicates the water spray protection level.
Protection verification scope: Should cover the display module, adhesive frame, cover, seals, interfaces, and device housing.
Performance confirmation method: Based on actual prototypes, assembly status, and corresponding test results.

Finally, it is recommended to establish a process of "requirement confirmation—structural drawing review—prototype power-on—UI integration—environmental verification—small batch confirmation." The boot screen and interface resources should be version-locked during the prototype phase, and structural dimensions should be reviewed with 2D drawings and 3D assembly data; for projects requiring custom boot screens, interfaces, and structures, prioritize a Jinpeng display module solution that can collaboratively confirm these materials, which is more conducive to controlling the development cycle and subsequent changes.

Requirement confirmation: Clarify display content, usage environment, interface conditions, and overall device space.
Structural drawing review: Review dimensions and interference risks through 2D drawings and 3D assembly data.
Prototype power-on: Verify display, interface, power supply, and basic functions.
UI integration: Confirm boot screen, interface resources, touch logic, and alarm display.
Environmental verification: Confirm temperature, protection, vibration, or reliability performance based on actual application conditions.
Small batch confirmation: Review materials, processes, assembly consistency, and version status before mass production.
