Industry refers to Apple's proposed increase in LED light strips to solve the new flat backlight problem

February 28, 2023
After Apple introduced the new smart phone iPhone 4S, when will the new tablet come out, and what kind of specifications and design look? Become a market concern. In terms of panels and backlights, panel makers pointed out that unlike the iPad 2 single LED strip design, Apple's new tablet backlight solution, there are currently two solutions to choose from, and it is expected that follow-up Apple changes The use of 2 LED strips has the highest probability.

Panel makers said that because the new tablet will use 2,048 x 1,536 higher resolution panels, and the panel resolution will increase, the luminous efficiency will be reduced. Therefore, the product needs to maintain the same brightness or higher brightness as the iPad 2, and must change the existing 1 The design of the root LED strip.

Corresponding to Apple's high-brightness demand, the industry currently offers two solutions for Apple to choose. One is to adopt a design of one LED light bar, but it is changed into two high-brightness LEDs in each LED package. Improve the luminous efficiency of the overall backlight module; the second is to convert the original design to two side-light LED strips.

The industry pointed out that no matter what design is adopted, how to keep the thickness of the product continuously is the biggest challenge. The main reason is that the backlight module design of iPad 2 has pushed the product thinner to the extreme. The subsequent products want to continuously reduce the thickness, which may affect the strength of the machine components. At the same time, increase the number of LEDs used, and related heat dissipation and battery capacity improvement, etc. Taiwanese companies have to complete new product development in a limited space, which is a product development problem faced by previous players.

The industry also predicts that Apple's new tablet is expected to be available at the end of the first quarter of 2012.
