ຫຼັກການແລະມຸມມອງທີ່ດີທີ່ສຸດຂອງຫນ້າຈໍສະແດງຜົນ LED

The imaging of full-color LED display screens is generally achieved through files, ວິດີໂອ, ຮູບພາບຕ່າງໆ, and text on the computer. Send to the sending card through the graphics card for transcoding processing. Then go to the receiving card to drive imaging. So how can we achieve the best display effect when choosing an LED display screen?

ຄຸນະພາບຂອງ ໜ້າ ຈໍຈໍສະແດງຜົນ LED ແມ່ນກ່ຽວຂ້ອງຢ່າງໃກ້ຊິດກັບປັດໃຈດັ່ງຕໍ່ໄປນີ້: ຄວາມສະຫວ່າງຂອງ ໜ້າ ຈໍສະແດງຜົນ, the width of the picture, and the optimal visual distance for installation. Only when each indicator meets the needs of the current usage environment, then the display effect is the best. ຈໍສະແດງຜົນແມ່ນປະກອບດ້ວຍຫລາຍລະບົບຍ່ອຍ, and we need to have a detailed understanding of each subsystem.

ມັນປະກອບມີການສະຫນອງພະລັງງານ, video encoder and decoder codes, line drivers, digital signal processors (DSPs), ແລະອື່ນ on, which work closely together to generate video images. If you carefully observe the LED display screen, ທ່ານຈະເຫັນຫຼາຍຮ້ອຍຄົນຂອງຫມູ່ຄະນະວິດີໂອ. If you get closer, you will find that each panel contains 16X16 pixels. anode ຂອງແຕ່ລະ LED ແມ່ນເຊື່ອມຕໍ່ໄຟຟ້າກັບຜົນຜະລິດຂອງໄດ LED. Ultimately, ເຄື່ອງຂັບ LED ຫລາຍສິບພັນຄັນເຫລົ່ານີ້ຈະຄວບຄຸມການຜະລິດຮູບພາບວີດີໂອຜ່ານລູກປັດ LED ຫລາຍຮ້ອຍພັນ ໜ່ວຍ.

The brightness of an LED display screen is not necessarily better the brighter it is. ໃນບາງສະພາບແວດລ້ອມ, brightness that is too bright or too dark cannot achieve the best display effect of the screen. When choosing an LED display ໜ້າ ຈໍ, it is necessary to match the most suitable brightness according to the usage scenario or adjust it automatically through a driver. This is the only way to provide satisfactory LED display quality without harming the audience’s eyes.

Most high-end LED drivers provide designers with multiple methods to control the LED current in their systems. ຄົນຂັບລົດເຫຼົ່ານີ້ມີຄຸນລັກສະນະບາງຢ່າງທີ່ຊ່ວຍຫຼຸດຜ່ອນຄວາມສະຫວ່າງຂອງ LED, ເຊັ່ນ: ການແກ້ໄຂຈຸດ (DC), ການວັດແທກຄວາມກວ້າງຂອງ ກຳ ມະຈອນ (PWM) dimming, and global brightness control (ກ່ອນຄ. ສ). Although these features all provide the same basic function of adjusting LED brightness, their usage is different. Understanding and utilizing these features correctly is the key to having the best quality video.

Regarding the wide viewing angle and optimal viewing distance of LED display screens, it is necessary to conduct standard measurement and calculation of the usage scenario before installation, calculate the required viewing angle and viewing distance, and then match them according to this requirement. This can ensure that the product meets the specific needs of the usage scenario and presents the most exciting and high-quality images to the audience.
