LCD Applications

In order to enable product development on character LCDs, character OLED LCDs and graphic LCDs manufactured by Winstar, as well as 4.3, 5 and 7 inch TFT screens manufactured by Satoz, 3 separate demo kits that can be programmed with the NUC029L demo kit were manufactured by Ozdisan Elektronik. There are 4 buttons on each product, 1 of which is a “Reset” button, as well as 1 potentiometer and 1 dip switch with 4 switches. The operating voltages of the LCDs vary between 3.3V and 5V. The demo kits manufactured by Ozdisan to be used in character LCDs and character OLED LCDs were offered for sale with the stock code EVA-CHAR-LCD-OLED-3V3-V1 for LCDs with a supply voltage of 3.3V and EVA-CHAR-LCD-OLED-5V-V1 for LCDs with a supply voltage of 5V. This demo kit can be used with a single software on WH0802, WH1602, WH1604, WH2002, WH2004, WH2402, WH4002 and WH4004 coded character LCDs and WEH0802, WEH1602 and WEH2004 coded character OLED LCDs. Once the LCD or OLED to be used is connected to the correct header on the demo kit, the desired LCD/OLED can be operated by adjusting the position of the switches on the PCB according to the product model. Two separate demo kits were manufactured by Ozdisan for graphic LCDs. Two separate versions were developed with the stock code EVA-WGLCD-128X64-5V-V1 for products operating at 5V voltage and stock code EVAWGLCD-128X64-3V3-V1 for products operating at 3.3V voltage to be used in Winstar 128×64 graphic LCDs. These two products support products with stock codes WG12864A, WG12864B and WG12864C, and can also be used on products with touch screen capability.

Another demo kit manufactured for graphic LCDs was offered for sale in two separate versions for LCDs operating at 3.3V and 5V voltages, with the stock codes EVA-GLCD240128/64- 5V-V1 and EVA-GLCD240128/64-3V3-V1. This demokit supports WG240128A, WG240128B, WG240128E and WG24064A models on Winstar 240×128 and 240×64 graphic LCDs, and can operate LCDs with touch screen capability. By means of the switches on the demo kit, touch screen adjustment, model selection and button settings can be made. For all these demo kits, contrast settings of LCDs can be made by turning the potentiometer on PCBs. Two demo kits manufactured for 128×64, 240×64 and 240×128 graphic LCDs can also be used on FT800- 810 boards. Thus, Satoz 4.3, 5 and 7 inch TFT screens can also be operated on these demo kits. 4.3-inch and 5-inch low-resolution TFT screens can be used with the FT800 board, while 5-inch high-resolution and 7-inch TFT screens can be used by attaching to the demo kit with the FT810 board. Once the connection is made, the system can be started by supplying 5V voltage to the FT800/FT810 board. There is no need to provide any supply voltage to the NUC029L demo kit. The software and technical specifications for these three demo kits with 3.3V and 5V versions that can be operated with Winstar branded character LCDs, character OLEDs, 128×64, 240×64 and 240×128 graphics LCDs and Satoz  branded  TFT screens, which are all available at Ozdisan inventory, can be found at On Ozdisan Elektronik website under technical library section.
