What is the pixel density of a 1.3 Inch TFT Square Screen?
Aug 19, 2025| Pixel density is a crucial factor when it comes to the visual quality of a display. As a supplier of 1.3 Inch TFT Square Screens, I often get asked about the pixel density of these screens. In this blog post, I'll delve into what pixel density means, how it's calculated, and specifically, what the pixel density of a 1.3 Inch TFT Square Screen typically is.
Understanding Pixel Density
Pixel density, often measured in pixels per inch (PPI), refers to the number of individual pixels that are packed into each inch of a display's surface. A higher pixel density generally means a sharper, more detailed image because there are more pixels available to display the content. This is particularly important for small screens like our 1.3 Inch TFT Square Screens, where the space is limited, and every pixel counts.
How to Calculate Pixel Density
The formula to calculate pixel density is based on the Pythagorean theorem. First, you need to know the number of pixels in the horizontal (X) and vertical (Y) directions of the screen. Then, you calculate the diagonal pixel count using the formula: Diagonal pixels = √(X² + Y²). Finally, you divide the diagonal pixel count by the physical diagonal size of the screen in inches to get the pixel density in PPI.
For example, if a screen has a resolution of 240 x 240 pixels and a diagonal size of 1.3 inches, the calculation would be as follows:
Diagonal pixels = √(240² + 240²) = √(57600 + 57600) = √115200 ≈ 339.41 pixels
Pixel density (PPI) = 339.41 / 1.3 ≈ 261 PPI
Pixel Density of 1.3 Inch TFT Square Screens
Our 1.3 Inch TFT Square Screens typically come with a resolution of 240 x 240 pixels. Using the calculation method described above, the pixel density of these screens is approximately 261 PPI. This pixel density provides a good balance between image quality and cost, making our screens suitable for a wide range of applications.
Importance of Pixel Density in 1.3 Inch TFT Square Screens
In a 1.3 Inch TFT Square Screen, a relatively high pixel density is essential for several reasons. Firstly, since the screen is small, a higher pixel density ensures that text and images appear sharp and clear. This is particularly important for applications where readability is crucial, such as smartwatches, fitness trackers, and other wearable devices.
Secondly, a higher pixel density can enhance the overall visual experience. It can make colors look more vibrant and details more distinct, which is appealing to users. Whether it's displaying a high - contrast graphic or a simple notification, a screen with a good pixel density will present the information in the best possible way.
Applications of 1.3 Inch TFT Square Screens
Our 1.3 Inch TFT Square Screens are used in a variety of industries. In the consumer electronics sector, they are commonly found in smartwatches and fitness bands. The high pixel density allows for clear display of time, fitness data, and notifications, enhancing the user experience.
In the industrial field, these screens can be used in handheld devices for monitoring and control purposes. The sharp image quality ensures that operators can easily read important data and instructions.
