Description
Le modèle WEX025664B-CTP est un écran graphique OLED COF de 3,12 pouces, riche en fonctionnalités, intégrant un panneau tactile capacitif avec une résolution de 256x64 points. Cet écran OLED avancé utilise un circuit intégré SSD1322, prenant en charge des interfaces polyvalentes 8 bits 6800/8080 et SPI 3/4 lignes. Avec des dimensions de 89,2×29,0 mm, il abrite une zone active de 76,778×19,178 mm.
Équipé pour afficher 4 bits de niveaux de gris, le module fonctionne avec une tension d'alimentation de 3,0V (valeur typique) et un cycle de service de 1/64. Conçu pour la polyvalence, il fonctionne de manière fiable dans une plage de température de -20°C à +70°C, avec une température de stockage allant de -30°C à +80°C. Notamment, ce modèle intègre un panneau tactile capacitif (CTP) avec le circuit intégré FT6336U, prenant en charge des interfaces I2C et offrant une fonctionnalité précise de toucher à un point.
Le module OLED se distingue par un remarquable rapport de contraste de 10 000:1, offrant des couleurs vives et fidèles à la réalité, des noirs profonds et des blancs lumineux. Cela améliore la qualité d'image globale, accentue les détails et améliore considérablement la lisibilité, surtout dans des conditions de faible luminosité, contribuant à une expérience visuelle immersive.
Le module OLED convient à diverses applications, notamment les dispositifs mur/mètre, les applications domestiques, les systèmes POS, les systèmes Cloud/IoT, les instruments portables, les dispositifs technologiques intelligents, les systèmes énergétiques, les applications automobiles, les systèmes de communication et les instruments médicaux. Les clients cherchant à passer des affichages traditionnels STN aux affichages OLED trouveront ce module attrayant, compte tenu de sa vaste gamme de formats de pixels adaptés aux solutions OLED.
De plus, la gamme de produits des mêmes panneaux OLED propose diverses alternatives :- Série WEX025664B sans cadre métallique et PCB.
- Série WEN025664B avec cadre métallique et PCB.
- Série WEN025664B-CTP avec cadre métallique, PCB et écran tactile CTP.

5 | VLSS | Analog system ground pin. | ||||||||||
6~13 | D7~D0 | Host Data Input/Output Bus These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. |
||||||||||
14 | E/RD# | Read/Write Enable or Read This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
15 | R/W# | Read/Write Select or Write This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it to “Low” for write mode. When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low. When serial mode is selected, this pin must be connected to VSS. |
||||||||||
16 | BS0 | Communicating Protocol Select These pins are MCU interface selection input. See the following table:
(1) 0 is connected to VSS (2) 1 is connected to VDDIO |
||||||||||
17 | BS1 | |||||||||||
18 | D/C# | Data/Command Control This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data. When the pin is pulled LOW, the content at D[7:0] will be interpreted as command. |
||||||||||
19 | CS# | Data/Command Control This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW. |
||||||||||
20 | RES# | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
||||||||||
21 | FR | This pin is No Connection pins. Nothing should be connected to this pin. This pin should be left open individually. | ||||||||||
22 | IREF | Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 10uA. |
||||||||||
23 | N.C. | Reserved Pin The N.C. pin between function pins are reserved for compatible and flexible design. |
||||||||||
24 | VDDIO | Power Supply for I/O Pin It should be matched with the MCU interface voltage level. |
