產品敘述

WO240128B單色COG LCD液晶顯示器是一款240x128點陣式4.8吋的繪圖型模組。WO240128B內建ST7586S 控制器IC, 支援多種傳輸介面: 6800 8-bit, 8080 8-bit 平行介面與3-線9-bit /4-線8-bit 串列SPI介面。WO240128B為COG結構模組,其VA區尺寸以及AA區尺寸與現有華凌標準品COB結構的WG240128B相同,但WO240128B為COG結構,所以模組厚度較薄,外形輕巧,具有低功耗,低供電等特點,客戶若有需求4.8吋模組的新案開發,建議可採用此WO240128B模組。

WO240128B的工作溫度是-20℃至+70℃,儲存溫度-30℃至+80℃,此型號目前有STN Negative 負顯, 與 FSTN positive正顯兩種玻璃可供選擇,可搭配LED白光,如有需求其他LCD或是LED背光組合可與我們聯繫。

產品規格

Pin功能定義

Pin No. 符號 說明
1 ESD GND Electro-Static discharge
2 VG VG is the power of SEG-drivers
3 XV0 Negative operating voltage of COM-drivers
4 V0 Positive operating voltage of COM-drivers
5 VM VM is the non-select voltage level of COM-drivers
6 VDDA Power supply
7 VSS Ground
8 VD1 Digital power source selection
9 VDDI VDD1 is the power of interface I/O circuit
10 CSB Chip select input pin
CSB=“L”: This chip is selected and the MPU interface is active
CSB=“H”: This chip is not selected and the MPU interface is disabled
(D[7:0] are high impedance)
11
12
13
IF3
IF2
IF1
These pins select interface operation mode

Note: Refer to “Interface Selection” for detailed information
14 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed
15 /RD(E) Read / Write execution control pin. (This pin is only used in parallelinterface)

This pin is not used in serial interfaces and should be connected to VDD1
16~23 D7~D0 The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface
D1 is the A0 signal in 4-Line interface
24 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface)

This pin is not used in serial interfaces and should be connected to VDD1
25 A0(SCL) The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input
26 ESD GND Electro-Static discharge
