GLK19264A-7T-1U-422-WB-E Application Field and Working Principle

Display Modules are integral components in many electronic products. They are used to deliver information more conveniently, thus enhancing users’ experience. GLK19264A-7T-1U-422-WB-E is a specific Display Module from a certain manufacturer and it is classified into the Display Modules - LCD, OLED, Graphic category. This article will briefly introduce its application field and working principle for the purpose of clarifying their usage.

Application Fields

GLK19264A-7T-1U-422-WB-E is a small-size graphic LCD, and it is especially applicable in the following fields:

• Medical Treatment: Whether in clinical experiment, medical treatment or patient management, GLK19264A-7T-1U-422-WB-E can offer vivid and accurate image display of patient’s information in the shortest period of time. By displaying the patient’s condition, it can reduce the possibility of misdiagnosis and improve the efficiency of medical practice.
• Industrial Controller: GLK19264A-7T-1U-422-WB-E can precisely display the data from the industrial field so as to help operators grasp the current conditions. This can improve the work efficiency of production.
• Educational Tools: GLK19264A-7T-1U-422-WB-E can improve the liveliness of learning by displaying various drawing, figures and texts in the class, which can not only capture the attention of students, but also provide a platform to better understand the knowledge.

GLK19264A-7T-1U-422-WB-E can also be used in other application fields, such as space science and oversea exploration, game machines and medical equipments, etc.

Working Principle

GLK19264A-7T-1U-422-WB-E works in the way of transmitting data from the Control Unit (or CPU ) to the LCD display panel. First, a timing controller demultiplexer (TCON) will generate a certain duration signal from the control signals received from the CPU and then convert it into the power supply signals.

The power supply signals are delivered to the LCD panel, where elements such as transistors, thin film transistor array, the liquid crystal medium and driving electrode will be activated. The analog signal inputted to TCON will be modulated, and therefore the signal can be delivered to corresponding LCD pixel, which will generate different size of voltage signal as response. Finally, signal voltage cycle will be adjusted to elicit the best effect of diffusing light according to the gray level scheme of the LCD display panel.

Let’s wind up this discussion. Ultimately, the working principle of GLK19264A-7T-1U-422-WB-E is that it processes the signal inputted from CPU to power supply signals, which will further act upon the LCD display panel to enable it to display items such as texts, figures and graphics visually.
