技術概要：グラフィック OLED カラーディスプレイモジュール
WEO012864MX は、128x64 ピクセルの解像度を持つ高コントラストな 0.96" OLED カラーディスプレイモジュールです。本モデルは、UIデザインに直感的な視覚階層を提供するため、固定デュアルカラーレイアウト（上部：イエロー、下部：スカイブルー）を採用しています。厚さわずか 1.26mm の COG 構造により、スペースが限られたハンドヘルド機器に最適なフレームレスソリューションを提供します。
SSD1306 内蔵電源ソリューション
内蔵の SSD1306 IC はチャージポンプ（DC/DC コンバータ）を搭載しており、VCC を内部で生成可能です。これにより、3V 単一電源での動作が可能となり、外部昇圧回路が不要になるため、BOM コストと PCB 設計の複雑さを大幅に削減できます。インターフェースは 8-bit 6800/8080 パラレル、3/4-wire SPI、I2C に対応しています。
- UI の最適化： 固定 2 色エリアにより、複雑な RGB プログラミングなしで情報のカテゴリ分けが可能。
- 統合の簡素化： 低電圧ロジック源から高電圧ディスプレイ駆動が可能な昇圧回路内蔵。
- 高い機械的効率： COG 構造によりフットプリントを削減し、耐久性を向上。
- 幅広い動作温度： 産業グレードの -40°C 〜 +80°C に対応。

| 15 | D/C# | Data/Command Control This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0 will be transferred to the command register. For detail relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams. When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. |
