What are the differences between IPS LCD screens and TFT screens?
News 2025-11-25
IPS and TFT LCD screens are two common display technologies. They each have unique technical characteristics and application scenarios. Today, we’ll delve into the differences between these two screen technologies and specifically mention the contributions of Hangzhou LEEHON Technology Co., Ltd. in this field.
Technical Principles
TFT (Thin Film Transistor) screens are an active-matrix liquid crystal display (LCD) technology. TFT screens control the display of each pixel by integrating thin-film transistors on the liquid crystal panel. Each pixel has a corresponding transistor, which can precisely control the deflection angle of the liquid crystal, thereby achieving image display.
IPS (In-Plane Switching) LCD screens are an improved technology developed based on TFT screens. The core feature of IPS screens is the different arrangement of liquid crystal molecules compared to TFT screens. In IPS screens, liquid crystal molecules deflect in a plane, rather than perpendicular to the screen surface as in TFT screens.
Display Effects
Viewing Angle: IPS screens have a very wide viewing angle, typically reaching around 178 degrees. This means that the screen maintains relatively consistent color and brightness regardless of the viewing angle. In contrast, TFT screens have a relatively narrow viewing angle, and color distortion and reduced brightness may occur when viewed from the side.
Color Reproduction: IPS screens excel in color reproduction, displaying a wide range of colors more accurately. This is because the arrangement of liquid crystal molecules in IPS screens shortens the path of light through the liquid crystal layer, reducing light scattering and deflection. TFT screens may have some shortcomings in color reproduction, especially when displaying vibrant colors, which may result in color deviation.
Response Speed and Power Consumption
Response Speed: TFT screens have a relatively fast response speed, better adapting to the display needs of dynamic images. For example, when watching fast-moving videos or playing games, TFT screens can switch pixel states more quickly, reducing motion blur. IPS screens, however, have a relatively slower response speed because the liquid crystal molecules need to make larger deflection angles within the plane.
Power Consumption: TFT screens have relatively low power consumption, making them widely used in devices with high battery life requirements. In contrast, IPS screens have relatively high power consumption, but with continuous technological advancements, the power consumption of IPS screens is gradually decreasing.
Application Scenarios
TFT Screens: TFT screens are widely used in various electronic devices, such as laptops, tablets, and mobile phones. They offer good cost-effectiveness while meeting basic display requirements.
IPS Screens: IPS screens are more commonly used in scenarios with higher display quality requirements, such as high-end monitors, professional image processing equipment, and high-end smartphones. These devices require wider viewing angles and more accurate color reproduction to meet the needs of professional users.
Contributions of Hangzhou LEEHON Technology Co., Ltd.
Hangzhou LEEHON Technology Co., Ltd., as a company with deep technical expertise in display technology, has always been committed to providing the market with high-quality display solutions.

Summary
IPS LCD screens and TFT screens each have their advantages and disadvantages. IPS screens perform excellently in terms of viewing angle and color reproduction, but their response speed is relatively slow and power consumption is higher; TFT screens have fast response speeds and low power consumption, but are slightly inferior in terms of viewing angle and color reproduction. The choice of screen should be based on specific application requirements. If you prioritize display quality and color accuracy, an IPS screen is a good choice; if you value battery life and response speed, a TFT screen might be more suitable.
