Edge-lit backlight module and scanning method thereof
View Patent ↗The present invention provides an edge-lit backlight module containing 2n+1 sequentially and equally separated backlight partitions where the 2n+1 backlight partitions are lit or turned off individually under a time-sequence control; a LCD panel scanned by the edge-lit backlight module is correspondingly separated into 2n+1 display partitions; the signal to the LCD panel is loaded into the LCD panel frame by frame and display partition by display partition under a time-sequence control; the time sequences to the signal to the LCD panel and the signal to the backlight partitions are controlled so that, whenever the signal loaded into the 2n+1 display partitions of the LCD panel constitutes a complete frame, the n+1 backlight partition in the middle of the edge-lit backlight module is always lit. The present invention also provides a scanning method of an edge-lit backlight module.
1. An edge-lit backlight module comprising 2n+1 sequentially and equally separated backlight partitions wherein n is a natural number greater than or equal to 1; the 2n+1 backlight partitions are lit or turned off individually and sequentially under a time-sequence control; a LCD panel scanned by the edge-lit backlight module is separated correspondingly into 2n+1 display partitions; the signal to the LCD panel is loaded into the LCD panel frame by frame and display partition by display partition sequentially under a time-sequence control; and the time sequences to the signal to the LCD panel and the signal to the backlight partitions are controlled so that, whenever a first backlight partition is lit, the first n+1 display partitions are loaded with a current frame for a first eye whereas the remaining n display partitions are loaded with a previous frame for a second eye; whenever the n+1 backlight partition in the middle of the edge-lit backlight module is lit, the 2n+1 display partitions are completely loaded with a current frame for the first eye; and, whenever a last backlight partition is lit, the first n display partitions are loaded with a next frame for the second eye whereas the remaining n+1 display partitions are loaded with the current frame for the first eye.
2. The edge-lit backlight module as claimed in claim 1 , wherein the edge-lit backlight module is a single-shorter-edge-lit backlight module.
3. The edge-lit backlight module as claimed in claim 1 , wherein the edge-lit backlight module is a dual-shorter-edge-lit backlight module.
4. The edge-lit backlight module as claimed in claim 1 , wherein n is equal to 1.
5. An edge-lit backlight module comprising 2n+1 sequentially and equally separated backlight partitions wherein n is a natural number greater than or equal to 1; the 2n+1 backlight partitions are lit or turned off individually under a time-sequence control; a LCD panel scanned by the edge-lit backlight module is correspondingly separated into 2n+1 display partitions; the signal to the LCD panel is loaded into the LCD panel frame by frame and display partition by display partition under a time-sequence control; the time sequences to the signal to the LCD panel and the signal to the backlight partitions are controlled so that, whenever a first backlight partition is lit, the first n+1 display partitions are loaded with a current frame for a first eye whereas the remaining n display partitions are loaded with a previous frame for a second eye; whenever the n+1 backlight partition in the middle of the edge-lit backlight module is lit, the 2n+1 display partitions are completely loaded with a current frame for the first eye; and whenever a last backlight partition is lit, the first n display partitions are loaded with a next frame for the second eye whereas the remaining n+1 display partitions are loaded with the current frame for the first eye; the edge-lit backlight module is a single-shorter-edge-lit backlight module; and n is equal to 1.
6. A scanning method of an edge-lit backlight module comprising the steps of:
separating the edge-lit backlight module sequentially and equally into 2n+1 backlight partitions where n is a natural number greater than or equal to 1;
separating a LCD panel correspondingly into 2n+1 display partitions where the signal to the LCD panel is loaded into the LCD panel frame by frame and display partition by display partition under a time sequence; and
controlling the time sequences to the signal to the LCD panel and the signal to the backlight partitions so that, whenever a first backlight partition is lit, the first n+1 display partitions are loaded with a current frame for a first eye whereas the remaining n display partitions are loaded with a previous frame for a second eye; whenever the n+1 backlight partition in the middle of the edge-lit backlight module is lit, the 2n+1 display partitions are completely loaded with a current frame for the first eye; and whenever a last backlight partition is lit, the first n display partitions are loaded with a next frame for the second eye whereas the remaining n+1 display partitions are loaded with the current frame for the first eye.
7. The scanning method as claimed in claim 6 , wherein the edge-lit backlight module is a single-shorter-edge-lit backlight module.
8. The scanning method as claimed in claim 6 , wherein the edge-lit backlight module is a dual-shorter-edge-lit backlight module.
9. The scanning method as claimed in claim 6 , wherein n is equal to 1.
