The difference between OGS technologies and Resistive touch screen, capacitive touch screen
OGS, resistive and capacitive touch screens are three touch technologies with high frequency. Among them, OGS touch technology is also a kind of capacitive touch screen, which is mainly used for larger-sized tft screens, such as tablet computers and notebook computers.
On Glass Sensor (OGS) technology is a type of touchscreen technology that has become increasingly popular in recent years. This technology has been used in a wide range of electronic devices, including smartphones, tablets, and laptops. OGS technology involves placing the touch sensors directly on the glass surface of the device, rather than using a separate layer for the sensors. This can lead to thinner and lighter devices, as well as improved touch sensitivity and image quality.
What is the difference between OGS, resistive and capacitive touch screens?
On-glass sensor technology is a touch technology that directly integrates the touch sensor On the protective cover plate. This eliminates the need for a separate layer of touch sensors, making the display thinner and lighter. The principle of OGS technology is the same as that of capacitive sensor. The difference is the location of the sensor. OGS can produce one layer of touch line or two layers of touch line to achieve different touch performance. So what’s the difference between resistive and capacitive touch screens?
Resistive touch screen involves two layers of conductive material separated by a small gap. When pressure is applied to the top layer, it comes into contact with the bottom layer, creating a change in electrical current that registers as a touch event. Resistive touch screens are relatively inexpensive, but they can be less responsive and accurate than other touch technologies.
Capacitive touch screen uses a layer of conductive material, typically indium tin oxide (ITO), to detect changes in capacitance caused by the presence of a conductive object, such as a finger. Capacitive touch screens are more responsive and accurate than resistive screens, but they can be more expensive.
In conclusion, on-glass sensor technology offers several advantages over other touch technologies, including a more responsive and accurate touch experience, as well as a thinner and lighter display. However, different touch technologies may be more appropriate for different use cases, depending on factors such as cost, durability, and power consumption.
How OGS Technology Works
OGS technology works by placing the touch sensors directly on the glass surface of the device. This is accomplished by using a thin layer of conductive material, such as indium tin oxide (ITO), to create the touch sensors. This layer is then bonded directly to the glass surface of the device using a special adhesive.
The use of a direct bond between the touch sensors and the glass surface of the device allows for several advantages over other touchscreen technologies. For example, because there is no separate layer for the touch sensors, OGS touchscreens can be made thinner and lighter than other touchscreens. Additionally, because the touch sensors are closer to the display, OGS touchscreens can provide improved image quality and touch sensitivity.
Advantages of OGS Technology
OGS technology offers several advantages over other touchscreen technologies, including:
1.Thinner and Lighter Devices: Because OGS touchscreens do not require a separate layer for the touch sensors, they can be made thinner and lighter than other touchscreens. This is particularly important in devices such as smartphones and tablets, where weight and thickness are important factors.
2.Improved Image Quality: Because the touch sensors are placed directly on the glass surface of the device, they are closer to the display. This can lead to improved image quality and clarity, particularly in devices with high-resolution displays.
3.Improved Touch Sensitivity: Because the touch sensors are closer to the display, OGS touchscreens can provide improved touch sensitivity. This can make the touchscreen more responsive and accurate, particularly when using multitouch gestures.
4.Lower Power Consumption: OGS touchscreens can also offer lower power consumption than other touchscreens. This is because the touch sensors are directly bonded to the glass surface of the device, which can reduce the amount of power required to operate the touchscreen.
Disadvantages of OGS touch screen
on glass solution has advantages in large sizes such as 7inch, 8inch,10.1inch,13.6inch and even 24 inch and larger tft display, compared to capacitive touch screen and resistive touch screen, OGS touch screen has simpler structure, higher transmittance, and lower price. But the OGS touch screen also has a disadvantage, because the sensor of the OGS touch screen is built on the cover glass. If the cover glass is extensively damaged, the touch will not work. On the other hand, capacitive touch screen and resistive touch screen are good, because the sensor is made on a flexible film and there is a high chance that it can use the touch function when the cover lens is damaged. This is something to be aware of when selecting a touch screen.
Applications of OGS Technology
OGS technology has been used in a wide range of electronic devices, including smartphones, tablets, laptops, and monitors. In smartphones and tablets, OGS touchscreens are particularly useful because they allow for thinner and lighter devices without sacrificing touch sensitivity or image quality. In laptops and monitors, OGS touchscreens can provide improved image quality and touch sensitivity, which can be particularly useful for design and creative professionals.
