What Is The Uniformity of TFT LCD Displays?

A thin film field effect transistor is known as a TFT. The term "thin film transistor" refers to the integrated thin film transistor that powers each liquid crystal pixel on a liquid crystal display. A liquid crystal display based on thin film transistors is known as a TFT LCD. Every pixel has a semiconductor switch installed in it. Dot pulses can be used to directly control every pixel. Because of each node's relative independence and ability to be continuously controlled, the TFT liquid crystal's color appears more realistic and its response speed is increased. Additionally, each node's display color gradation can be precisely controlled. What is the TFT LCD display's uniformity, then?


1. The TFT LCD display's specific performance about its unevenness

The display effect will typically reflect the TFT LCD display's uneven display. The local display is either brighter or darker than the surrounding areas. The brightness varies noticeably, and certain uneven TFT LCD display modules can even result in other phenomena like backlight leakage. One prevalent issue with TFT LCD screens is their uneven brightness. The average user of a TFT LCD screen that has uneven brightness is more likely to become fatigued, and the display effect is generally poor when using a specific white or black screen. more apparent.


2. The techniques used to assess the TFT LCD display's uniformity

Measurements can be used to determine the TFT LCD display's uniformity, which can then be obtained using the average brightness distribution uniformity calculation formula. It is not evaluated by using the unaided eye because variations might exist. Here, Reshine Display provides the formula. To all: the TFT LCD display's uniformity is equal to the minimum brightness ÷ maximum brightness × 100%. The better the uniformity of the TFT LCD display, the higher its uniformity value.


An overview of the TFT LCD display's uniformity can be found in the material above. Every pixel on the TFT LCD display has a semiconductor switch. Since a dot pulse can directly control each pixel, each node is comparatively independent. It can be continuously adjusted, which enhances the display screen's response time and precisely regulates the color gradation of the display, making the TFT LCD's color more accurate.


3. The Variations of TFT Monochrome Screen and TFT Color Screen

The variety of LCD monitor module screens has increased along with the display technology's ongoing innovation, and various display products have also been used in various industry terminals. What are the primary distinctions between a monochrome and a TFT color screen?


3.1 How TFT color and TFT monochrome screens operate differently

A. TFT display screen in monochrome

The TFT color display screen and the monochrome screen operate for entirely different reasons. The seven pen segments that make up the monochrome screen are made up of numerous points within a range known as pixels. All of the monochrome screens have fixed sizes. An array is created from these points; for instance, 12864 is made up of 64 points in the vertical direction and 128X in the horizontal direction. Monochrome screens go by many different names, including digital screens, pen-segment LCD screens, pattern LCD screens, dot matrix screens, and so forth.


B. Color TFT screen

Liquid crystal material is placed between two parallel plates to fill the TFT color screen. The arrangement of molecules within the liquid crystal material is altered by voltage to achieve the desired effects of shading and light transmission, allowing images with varying shades and staggered patterns to be displayed. The display of color images can be achieved by interchanging the plates with a filter layer that contains three primary colors. As a result, the TFT color screen and monochrome screen operate on entirely different principles.


3.2 The various uses for TFT color and TFT monochrome screens

Typically, watches, remote controls, calculators, phones, and other devices have monochrome TFT display screens. Nonetheless, TFT color screens are found in many products, including video phones, walkie-talkies, smart homes, artificial intelligence, handheld terminals, and high-end smartphones. A TFT color screen will become increasingly common for terminal products to choose as their display device.


3.3 The variations in cost between TFT monochrome and color screens

Because of the different raw materials and production processes, the higher raw material requirements for TFT color screens, the more complex processing technology, the higher cost, and the more well-liked product performance, TFT color screens are more expensive than monochrome TFT display screens. A common issue with monochrome TFT display screens is their high MOQ. Monochrome TFT display screen manufacturers typically increase the number of orders due to their low cost.


The two most popular types of display screens available today are TFT color screens and monochrome screens. The only certain thing is which type of display screen is more appropriate, not who is superior. There are benefits and drawbacks to both TFT color and monochrome displays. Everyone's choices ought to be logical.
