Futuristic Brand Upgrade Conference Poster

Objective: Create a futuristic vertical conference poster for a technology brand upgrade event, centered around large, glossy 3D typography and abstract digital wave landscapes.

Canvas: 9:16 vertical poster, dark navy to black background, high contrast, high-end tech conference aesthetic. Ample black space at the top and bottom, with the main title positioned in the upper-middle of the poster.

Visual Style: Minimalist sci-fi event design, illuminated electric blue and violet accents, metallic white/silver typography, soft glow effects, subtle lens flares, realistic 3D beveled typography, clean business-tech atmosphere. The background should present a vast ocean of data composed of illuminated dot-matrix wave grids and flowing neon lines, brightest at the central horizon.

Top Brand Identification: Place a small abstract X-shaped logo centered at the top, followed by the brand text {argument name="brand name" default="X·SYS"}. Below that, add small-cap subtitle text: “SYSTEM UPGRADE”.

Main Title Typography: Create two lines of stacked, massive custom 3D display text reading {argument name="main title" default="HELLO WORLD"}. The letters should be rounded, blocky, and futuristic in style, rendered in glossy silver with bevels, shadows, and embedded tech details. Add 7 distinct decorative letter details: a dot-matrix vertical panel inside the H, a small rectangular crossbar inside the H, a dot-matrix panel at the bottom of the E/L areas, a cyan line panel inside the E, a concentric neon cyan ring inside the O of HELLO, a purple neon ring inside the O of WORLD, and a striped diagonal insert inside the R. Add additional subtle recesses and small dot-matrix perforations only if they don’t create visual clutter.

Mid and Bottom Text Content: Below the digital wave horizon, center clean, widely spaced sans-serif typography with event information. Use Chinese title text {argument name="Chinese event headline" default="Brand Upgrade Launch Conference"}, accompanied by a smaller English subtitle: “BRAND UPGRADE CONFERENCE”. Below that, display “= Annual Kickoff =”, flanked by small cyan and purple equal sign decorations. Below that, add a tiny glowing compass/star icon. Then display the date and time {argument name="date and time" default="2025.05.20  14:00"}. Below the date line, display “Shenzhen, China | SHENZHEN, CHINA”. Near the bottom, add a small, fine-line spiral system icon, and the slogan {argument name="bottom slogan" default="NEW SYSTEM  NEW FUTURE"} presented in small-cap letters.

Composition: All text must be strictly centered along the vertical axis. The massive “HELLO WORLD” title should occupy roughly half the height of the poster. Digital waves should pass through behind and below the title, forming an illuminated horizontal valley with blue and purple particle trails. The image should not contain people, photos of physical venues, additional logos, or watermarks.
