LSA40AT9001 Compatible alternative LCD recommended TM104SDHG30
Date:2019-06-21
Previously, we issued the notice of lsa40at9001 stop production given by Qun Chuang optoelectronics. Looking at the production cycle of lsa40at9001: 2009, Q3 customer sample delivery, 2009, Q4 mass production, 2019, Q1 final order, 2019, Q1 final shipment, the whole production cycle has 10 years, we can imagine the market consumption and customer demand of lsa40at9001.
For the customers who have used lsa40at9001 LCD for a long time, how to solve the problem of using LCD in the later product development in the face of the sudden stop of production notice of Qun Chuang optoelectronics.
Solution 1: the notice says that the final shipment will be made in 2019 and Q1. I believe that many customers can still order lsa40at9001 on demand. According to the usual market practice, lsa40at9001 can still meet the needs of customers in Q1 2020, so we should prepare for large-scale use of lsa40at9001 before it is out of stock.
Solution 2: new project selection can directly ignore lsa40at9001 screen, old project can choose compatible alternative LCD screen, tm104sdhg30 and a104sn03 v1. Without changing the structure and circuit, tm104sdhg30 is the best alternative screen.
