How to read and understand LCD drawings?

LCD displays are widely used in intelligent terminal products in various industries. When you buy LCD liquid crystal display, manufacturers usually provide relevant CAD drawings, but many end customers said it is difficult to understand. Today, we will teach you how to interpret LCD display drawings, mainly focusing on the following points:

I. LCD Liquid Crystal Display Size

Size contains several key parts. The actual size, such as 5 inches, 7 inches, 8 inches, etc., visualizes the size of the display. Outline size refers to the size range covered by the entire LCD bezel, which determines the overall space occupied by the display in the installation of external equipment. And Active Area size is the most important, this is the real display area, to Apple 6 or Apple 7 cell phone, for example, its form factor is larger than the display area, through the comparison can be more intuitive understanding of the concept of Active Area size. In addition, the thickness of the LCD display should not be ignored, these dimensions are directly related to the final installation, so be sure to pay special attention.

2.LCD screen interface definition

Interface Pin definition is an important content of LCD display drawings, the drawings will show in detail the alignment of each pin and the definition of the specific connection. In practice, these interface definitions need to be accurately matched with the motherboard, which is also the focus of many industry terminal designers, only matching correctly to ensure stable data transmission and normal operation between the display and the motherboard.

3. Description of Technical Parameters

The technical parameter descriptions in the drawings cover the key information of the LCD. These include the model number of the Driver IC, which affects the performance and functionality of the display; the viewing angle determines the clarity and color performance of the display when viewed from different viewing angles; and the temperature description relates to the range of temperatures in which the display can operate normally, which is critical for devices used in special environments. In addition, the material of FPC (Flexible Printed Circuit Board), the structure and brand of the cover, as well as whether to comply with ROHS (Directive on Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment) and other environmental protection standards, these parameters are detailed in the technical parameters section, which is of great significance for a comprehensive understanding of the performance and applicability of the display.
