Bagaimana Cara Memastikan Keseragaman Piksel dalam Tampilan Resolusi Tinggi?<\/h2>\n

[\/vc_column_text][vc_empty_space height=”18px”][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/4″][vc_empty_space height=”8px”][vc_single_image image=”14294″ img_size=”full”][\/vc_column][vc_column width=”3\/4″][vc_empty_space height=”18px”][vc_column_text css=””]Dewasa ini, orang-orang semakin menginginkan panel layar dengan resolusi yang lebih tinggi pada perangkat elektronik mereka seperti telepon pintar<\/a>, laptop, televisi, dll. Hal ini mendorong perkembangan dari teknologi layar kristal cair (LCD) menuju teknologi layar dengan kepadatan piksel seperti OLED (organic light-emitting diode)<\/a>, microLED<\/a>, dll. Akan tetapi, seiring meningkatnya kepadatan piksel, semakin sulit bagi produsen layar untuk memeriksa kualitas layar, terutama kecerahan dan keseragaman warna.<\/p>\n

Tantangan Dalam Mengukur Tampilan Padat Piksel<\/strong><\/p>\n

Layar seperti OLED dan microLED bersifat emisif, di mana setiap piksel, yang terdiri dari subpiksel merah, hijau, dan biru, menghasilkan cahayanya sendiri secara independen. Hal ini dapat mengakibatkan variasi kecerahan dan keluaran warna dari piksel ke piksel, yang menyebabkan tampilan yang tidak seragam di seluruh layar. Memperbaiki tampilan emisif di mana input setiap subpiksel disesuaikan secara individual diperlukan untuk mencapai kecerahan dan warna yang seragam di seluruh layar. Metode umum untuk mengoreksi keseragaman tampilan melibatkan penggunaan sistem pencitraan untuk mengukur luminansi dan kromatisitas masing-masing subpiksel. Nilai luminansi dan kromatisitas yang diukur kemudian digunakan untuk menghitung koefisien koreksi yang akan diterapkan pada sinyal setiap subpiksel.<\/p>\n

Namun, seiring dengan meningkatnya resolusi dan piksel per inci (PPI) layar, memastikan pengukuran yang akurat dan berulang menjadi lebih menantang. Sistem pencitraan harus memiliki lebih banyak piksel sensor (resolusi kamera)<\/a> daripada piksel tampilan (resolusi layar) untuk menangkap data luminansi dan kromatisitas secara akurat dan cepat. Namun seiring bertambahnya jumlah piksel keseluruhan dalam sebuah layar, kemampuan sistem pencitraan untuk mengalokasikan piksel sensor yang cukup per piksel layar akan berkurang. Seperti yang ditunjukkan dalam contoh ilustratif di bawah, sistem pencitraan mungkin memiliki piksel sensor yang cukup untuk menutupi piksel tampilan di tampilan A, namun kehilangan presisi pengukuran saat menggunakan tampilan beresolusi lebih tinggi seperti tampilan B.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/5″][\/vc_column_inner][vc_column_inner width=”3\/5″][vc_single_image image=”14295″ img_size=”full” alignment=”center”][vc_column_text css=””]<\/p>\n

[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/5″][\/vc_column_inner][\/vc_row_inner][vc_column_text css=””]Meskipun memungkinkan untuk mengukur beberapa bagian layar dan menggabungkan semua gambar untuk mengatasi keterbatasan resolusi sistem pencitraan, metode ini tidak efisien untuk memenuhi persyaratan waktu takt produksi volume tinggi. Tantangan lain saat mengukur layar berkerapatan piksel adalah kedekatan piksel. Karena piksel sangat dekat satu sama lain, metode pengukuran piksel utuh tradisional dapat memperhitungkan luminansi piksel di sekitarnya, sehingga menghasilkan variabilitas luminansi piksel yang salah.<\/p>\n

Metode Piksel Pecahan<\/strong><\/p>\n

Pendekatan pengukuran yang lebih baik menggunakan metode piksel fraksional<\/a> oleh Radiant Vision Systems (RVS) menawarkan pengukuran piksel dan subpiksel yang akurat bahkan ketika piksel sensor sistem pencitraan per piksel tampilan terbatas. Metode ini menggunakan nilai luminansi rata-rata untuk menetapkan dan memusatkan wilayah minat (ROI) pada piksel tampilan, bukan piksel sensor. Selanjutnya, metode ini menghitung luminansi dan kromatisitas piksel berdasarkan proporsi setiap piksel sensor dalam ROI, berbeda dengan metode pengukuran tradisional yang menggunakan 100% data hanya dari piksel sensor yang luasnya lebih dari ukuran tertentu dalam ROI.[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/5″][\/vc_column_inner][vc_column_inner width=”3\/5″][vc_single_image image=”14296″ img_size=”full” alignment=”center”][vc_column_text css=””]<\/p>\n

Pemeriksaan tampilan beresolusi tinggi dan kepadatan piksel dipermudah dengan Kolorimeter Pencitraan ProMetric\u00ae seri I<\/a> dan Fotometer Pencitraan seri Y<\/a> yang dilengkapi dengan sensor gambar tingkat ilmiah yang menawarkan resolusi spasial tinggi hingga 61 MP. Bersama dengan kemampuan kecepatan tinggi dan jangkauan dinamis yang luas, kolorimeter pencitraan dan fotometer ProMetric\u00ae dapat dengan mudah mengukur piksel dan subpiksel tampilan dengan akurasi dan kecepatan yang dapat diulang. Dengan menggabungkan instrumen pengukuran tampilan Konica Minolta Sensing seperti penganalisis warna<\/a> dan spektroradiometer<\/a>, karakteristik utama tampilan<\/a> lainnya, termasuk gamut warna<\/a>, gamma<\/a>, kedipan<\/a>, dll., dapat dievaluasi dengan mudah.<\/p>\n
