Low Cost Display Touch Screen

Challenge Today for an Exciting Tomorrow

ACTIVITIES & INFORMATION

Corporate Social Responsibility (CSR) is a concept that organizations—particularly, though not exclusively, companies—have various forms of responsibility toward all of their stakeholders. These stakeholders include consumers, employees, shareholders, communities, and the environment, across all aspects of the company’s operations, encompassing economic, social, and environmental dimensions.

Generally, a touchscreen display is constructed with a structure consisting of a Touch Panel + LCD + Control Board. By using an LCD, dynamic menus can be displayed—meaning that when a menu is pressed, it can call up another menu or display a different image.

However, there are times when dynamic menus are not necessary, and only static menus are required (menus that do not switch to other menus). In such cases, we can use a Resistive Touch Panel, stickers, and an Arduino!

The block diagram is as follows:

The size of the Touch Screen can be adjusted according to specific needs. Stickers will be created/printed to display the required menus. Once the sticker is applied to the touch panel, the Arduino must be programmed to respond when a menu item on the sticker is pressed.

Device Prototype

We have developed a prototype device that utilizes components such as a resistive touch screen, sticker, and Arduino. The device we created can be seen in the image below.
