When an electronic product is determined to use a TFT color screen, how do you choose the optimal TFT color screen solution?
First, determine the required size for the color screen.
The color screen's length, width, and size range are determined by the structure of electronic products; the thickness also plays a role in this. Next, you need to let the TFT factory of your choice know which size range of ready-made mold color screen you have selected. They can then verify this information.
Second, pay attention to the screen's resolution range within this size range, based on the driving power of your primary control. Next, select a low score for cost-effectiveness or a high score for effect in the resolution of the drive's size, depending on whether you want to maximize the effect or the cost-effectiveness.
Third, the resolution size is established; we need to consider whether the motherboard is pre-built or specially designed. If the motherboard is off-the-shelf, you will need to develop your motherboard to interface with the TFT LCD factory using the current motherboard pin. Take the ready-made development directly out of the factory if the motherboard is customized based on the volume of the largest pin definition and interface currently found in the screen factory. Continuous supply and easy delivery. Additionally, it should be mentioned that the screen typically has a variety of interfaces, including RGB, LVDS, EDP, Mipi, MCU, and SpI interfaces. The interface is not suitable, or the screen cannot be used when the motherboard demands an interface. Can increase the conversion interface chip.
The screen also has an important parameter: brightness. Look at the scene you use. Indoor ordinary brightness, or outdoor sunlight visual brightness, brightness and cost-related, and power consumption are also related. Different scenes of customers demand different screen brightness.
Fourth, we must ascertain whether the product has touch after completing the single-screen program. Is it better to use capacitive touch or resistive touch when performing the GG, GFF, or GF processes? A full paste or frame paste is the last layer of lamination. Whether shielding film needs to be laminated or not, military customers typically need to complete the shielding film along with the laminated
TFT (thin film transistor) displays are becoming commonplace in our daily lives. These screens, which can be found in smartphones, TVs, tablets, and computer monitors, are well-liked for their superb color and image quality. However, how precisely do they render images and create such vibrant patterns? Below, we will delve into the working principles of TFT displays.
Each pixel in a TFT display is the basic building block of an image. Each pixel consists of three sub-pixels, usually red, green, and blue, which form the basis of the colors seen. These sub-pixels consist of liquid crystals, color filters, and transparent electrodes.
Liquid Crystals: Liquid crystals are special liquids that can have their molecular arrangement altered by applying a voltage, thereby controlling the transmission of light. When voltage is applied to a liquid crystal, it twists or rotates, thus changing the way light travels. Different voltage levels can change the degree of distortion of the liquid crystal, thereby controlling the amount of light transmitted.
Color Filters: In front of each pixel, there are three color filters: red, green, and blue. These filters determine the color of each sub-pixel. For example, the red filter allows only red light to be transmitted, the green filter only green light, and the blue filter only blue light. Combining these colors of transmitted light creates a variety of colors.
Transparent Electrodes: Transparent electrodes are located between the liquid crystal and the color filter, and they are used to apply voltage to the liquid crystal layer. Different voltage levels result in different distortions of the liquid crystal, which affect the transmitted light.
By controlling the voltage for each sub-pixel, the TFT display can produce the desired color and brightness to build the entire image.
TFT displays usually have a backlight source behind them to provide brightness to the screen. This backlight source can use technologies such as LED or CCFL. The backlight source emits white light, and then this light passes through the liquid crystal layer, color filters, and transparent electrodes to finally form the image we see. The brightness and uniformity of the backlight source are very important to the performance of the display. The brightness of the backlight determines the overall brightness level of the screen, while uniformity ensures an even distribution of light across the screen to avoid uneven brightness.
TFT displays use rapid refresh rates to alter the voltage of individual pixels, thereby changing their states. Tens of times per second or more is the usual refresh rate, which makes sure the screen can display a continuous image and react quickly to input signals. To render smooth patterns, text, and images, control circuits continuously update the voltage to the pixels, changing their state. With a high refresh rate, images are rendered smoothly and crisply, making it ideal for interactive activities like playing games, watching videos, and performing interactive tasks.
By adjusting the liquid crystal voltage at each pixel, TFT displays make use of the backlight's brightness to present crisp, colorful patterns and images at a fast refresh rate. We can take advantage of outstanding display effects and visual experiences on a variety of devices thanks to this intricate and sophisticated process.
