Pero este tipo de sensor requiere de una pantalla OLED para poder detectar con precisi\u00f3n las huellas de sus usuarios y eso encarece los costos. Sin embargo, <strong><a href=\"https:\/\/www.smart-gsm.com\/fabricantes\/xiaomi\">Redmi<\/a><\/strong> anuncia un lector de huellas para display LCD.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El primero de su estirpe, de hecho, y de all\u00ed la importancia de esta revelaci\u00f3n preliminar. Si bien se trata de un prototipo lo que Redmi tiene en sus manos es tecnolog\u00eda con el potencial para una peque\u00f1a revoluci\u00f3n en el mercado de smartphones de mediana y baja gama, lo que podr\u00eda ocurrir mucho antes de lo que cre\u00edamos.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">\u00bfC\u00f3mo funciona el lector de huellas dactilares en un display LCD?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La raz\u00f3n por la cual los lectores de huellas dactilares intra-display consiguieron funcionar primero en pantallas OLED, que de por s\u00ed son m\u00e1s caras que los paneles LCD, es porque estos sensores pueden &#8220;espiar&#8221; a trav\u00e9s de los p\u00edxeles aut\u00f3nomos del display OLED. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En cambio, entre los p\u00edxeles de un panel LCD y sus componentes interiores hay una pantalla oscura que dificulta enormemente la tarea para los lectores intra-display sin importar si son \u00f3pticos o ultras\u00f3nicos. \u00bfC\u00f3mo ha conseguido entonces Redmi resolver este aparentemente imposible acertijo? Con tecnolog\u00eda infrarroja.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La tecnolog\u00eda de transmisores de luz infrarroja ha mejorado al punto en que puede penetrar con su luz el oscuro panel del reverso del display LCD y llegar as\u00ed hasta la huella. El camino inverso, el de la reflexi\u00f3n de la luz infarroja, se da de la misma manera: sin dificultades para la luz de este tipo y as\u00ed el sensor puede captar la informaci\u00f3n necesaria para identificar la huella.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pero, \u00bfqu\u00e9 tan preciso es este lector de huellas intra-display en comparaci\u00f3n con los que funcionan con paneles OLED? No lo sabemos. Principalmente porque Redmi ha revelado apenas un prototipo de este sensor y no ser\u00eda justo juzgar su respuesta en tan temprana etapa de su desarrollo.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No obstante es importante notar que los lectores de huellas dactilares externos suelen ser mucho m\u00e1s veloces, precisos, seguros e incluso econ\u00f3micos que la popular versi\u00f3n intra-display presente en casi todos los smartphones de jerarqu\u00eda premium de la actualidad. La realidad es que estos se eligen como medida est\u00e9tica m\u00e1s que por su calidad.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Redmi anuncia un lector de huellas para display LCD y eso le permitir\u00eda a smartphones de mediana y baja gama acortar a\u00fan m\u00e1s la brecha que los separa de los tel\u00e9fonos de la m\u00e1s alta jerarqu\u00eda. Esperamos con ansias al lanzamiento del primer smartphone con este tipo de tecnolog\u00eda que bien podr\u00eda llegar en 2020.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Redmi podr\u00eda llegar a revolucionar el mercado de smartphones econ\u00f3micos tras presentar el primer lector de huellas para pantallas LCD.<\/p>\n","protected":false},"author":2,"featured_media":81954,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"rop_custom_images_group":[],"rop_custom_messages_group":[],"rop_publish_now":"initial","rop_publish_now_accounts":[],"rop_publish_now_history":[],"rop_publish_now_status":"pending","footnotes":""},"categories":[4128],"tags":[3163,2180],"class_list":["post-81952","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tecnologia","tag-redmi","tag-xiaomi"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.0 -
