Display Effect: A Technical Showdown of a Visual Feast OLED screens’ pixel-level light control capabilities deliver a revolutionary experience. When displaying black scenes, OLED pixels simply turn off their light, creating a deep, near-realistic black. This technological feature enables a contrast ratio exceeding 100,000:1, far exceeding LCD’s 1,000:1-3,000:1. In the five-dimensional space sequence from Netflix’s […]
Medical: The guardian of life with precise touch In modern medical equipment, capacitive touch screens have become the preferred interactive solution for monitors and ultrasound equipment with their high sensitivity and anti-pollution characteristics. Doctors can directly slide the screen to retrieve three-dimensional images during surgery, and complete lesion marking and data sharing with a light touch […]
Technical ceiling: the underlying bottleneck of OLED life The core of OLED lies in self-luminous organic materials, especially the aging speed of blue pixels can reach 3 times that of red pixels. The natural defects of this organic material are the root cause of the lifespan problem – when the aging speed of sub-pixels of different […]
1. TFT LCD screen: a precise canvas of pixel matrix As the “visual cortex” of the module, the TFT LCD screen accurately controls the light on and off of each sub-millimeter pixel through a thin-film transistor array. Its advantages are: High contrast: up to 1500:1 (such as high-end mobile phone screens), making black deeper and […]
Today, when digital interaction is ubiquitous, fingertip touch has become the most natural bridge connecting people and machines. The core supporting this magic is the unique absolute coordinate system of the touch screen: each touch independently generates precise coordinate data, which is directly mapped to the screen position after calibration. This system ensures the high […]
1. Technological evolution and diversified development Touch screen technology has formed a pattern of coexistence of multiple technical routes. Resistive screen, as an early representative, achieves positioning through physical contact between two conductive layers. Its advantage is that it is compatible with any object touch, from fingers to gloves and even pen tips, and it is low-cost. […]
1. Electroluminescence: the Quantum Dance of Energy Conversion The luminous essence of OLED is the quantum process by which electrical energy is directly converted into light energy.When an electric current passes through the organic light-emitting layer, electrons and holes are combined under the drive of an electric field, and the released energy excites the organic […]
1. Precise helmsman of pixels: realizing active matrix control The core role of TFT is to equip each pixel with an independent “electronic switch”. Imagine millions of pixels on a mobile phone screen: traditional passive matrix LCDs have difficulty in independently and accurately controlling each pixel, resulting in slow response and high crosstalk. TFT is […]

1. Η φύση της τεχνολογίας: το χάσμα μεταξύ παθητικής και ενεργού Οι παραδοσιακές οθόνες LCD (που συχνά αναφέρονται σε οθόνες παθητικής μήτρας, όπως οι TN/VA) βασίζονται σε εξωτερική τάση για την αργή οδήγηση ολόκληρης της γραμμής/στήλης των εικονοστοιχείων. Οι TFT-LCD ενσωματώνουν μικρολεπτά τρανζίστορ φιλμ ως ανεξάρτητους διακόπτες σε κάθε εικονοστοιχείο για την επίτευξη ακριβούς και γρήγορου ελέγχου φόρτισης. Το Εθνικό Ινστιτούτο Προτύπων [...]
