Some analog voltage dividers can be used to generate analog bias voltages. They can also be directly driven by a single-chip microcomputer. However, the programming is too complicated and the display effect is not ideal. It is best to use a dedicated segment code LCD driver chip. The most commonly used is the HT1621, which is low in price. 3-wire SPI serial port driver, programming is also simple.\u003c\/span\u003e\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eDownload:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eEDS803 product sample download link:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003ehttp:\/\/pmoc98298.pic37.websiteonline.cn\/upload\/EDS803.pdf\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eEDS803 side backlight sample download link:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003ehttp:\/\/pmoc98298.pic37.websiteonline.cn\/upload\/EDS803-D.pdf\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eLCD application technology:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003ehttps:\/\/pan.baidu.com\/s\/1x1TBcAJwxn-MPjqYkiqM-A\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eHow the LCD display works:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003ehttps:\/\/pan.baidu.com\/s\/15VEqI07qAMUqCzNd73tERA\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003eStatic segment LCD screen drive method:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan style=\"font-size:14px;\"\u003ehttps:\/\/pan.baidu.com\/s\/1KHg1MMgBvTnq50WY4oiHiQ\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\u003cstrong\u003e\u003cspan style=\"font-size:16px;\"\u003ePackage Included:\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/div\u003e\u003cdiv\u003e \u003c\/div\u003e\u003cdiv\u003e\n\u003cspan style=\"font-size:14px;\"\u003e1 x Blue\/ Green\/ White \u003c\/span\u003e\u003cspan style=\"font-size: 14px;\"\u003eEDS803\u003c\/span\u003e\u003cspan style=\"font-size:14px;\"\u003e LCD Display Screen\u003c\/span\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cimg alt=\"\" class=\"ED139 LCD Display Screen\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/5D\/60\/5675e602-d7bc-43b7-837b-c56bdaf045d8.jpg\" title=\"ED139 LCD Display Screen\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/D5\/34\/43e21a3c-9123-4450-a527-d74252acafed.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/9E\/96\/8cae1d53-f8b7-43ce-9dbe-f6c7e72d0969.jpg\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/44\/6F\/0861194f-b041-4e2f-98f3-00fdbfccbd7d.JPG\"\u003e\u003cbr\u003e\u003cbr\u003e\u003cimg alt=\"\" src=\"https:\/\/img.staticbg.com\/images\/oaupload\/banggood\/images\/3D\/CC\/4a7fb627-350f-46a4-b2f1-0090394e4e77.JPG\"\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Shopify","offers":[{"title":"Default Title","offer_id":14008676548652,"sku":"1383742","price":750.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2787\/9162\/products\/87d33ca3-9b83-4d39-947b-bc94342c7306_c52adff4-8921-4a96-be7d-f75453a589c2.jpg?v=1587027622","url":"https:\/\/electronic-pro-south-africa.myshopify.com\/products\/eds803-5v-6-digit-7-segment-lcd-display-screen-static-driving-tn-positive-display-with-backlight-blu","provider":"Electronic Pro ","version":"1.0","type":"link"}
