Benefits of technology

This patented technology describes an improved way to make displays brighter by adding multiple small lights at different locations within them. It involves connecting two or three rows of LEDs together through wires that are controlled separately from one other. By adjusting these connections based upon factors like brightness levels and resolution requirements, it becomes possible to create customized images without requiring expensive equipment such as lamps. Overall this innovation improves display performance while reducing costs compared to traditional methods.

Problems solved by technology

This patented technical problem addressed during this patents relate to improving the efficiency and effectiveness of replacing existing displays used in computers without compromising their original purpose. Specifically, there are challenges associated with achieving higher levels of lumen output while maintaining good visual contrast characteristics such as brilliance and clarity at reduced power usage rates due to increased use of LED lights. Current solutions involve adding more expensive components like quantum dots instead of white OLED technology but these methods have drawbacks including decreased overall conversion efficacy caused by loss of light energy within each component's own portion.

Embodiment Construction

[0017] Please refer to FIG. 2, which is a schematic diagram showing the liquid crystal display device cooperating with the matrix type backlight module of the present invention. As shown in FIG. 2, the liquid crystal display device 100 comprises a matrix type backlight module 10 for forming a planar light source in which each of the plurality of light spots can be independently modulated. A black matrix layer 20 is disposed on top of the matrix type backlight module 10 to separate the light between the light spots in proximity. A thin film transistor (TFT) layer 30 is disposed on top of the black matrix layer 20 for forming each of the plurality of pixels for the liquid crystal display device. The number of pixels of the thin film transistor layer 30 can be the number of the light spots of the matrix type backlight module or its multiple, in order to make each of the plurality of light spots of the matrix type backlight module 10 corresponding to one or n of the pixels of the thin film
