Abstract

The invention discloses a blending type LED backlight comprising an LED light bar and at least one main LED, wherein the main LEDs are evenly distributed on the LED light bar, at least one secondary LED is arranged between the main LEDs, the colour gamut of the secondary LED is same with the colour gamut of the main LEDs, and at least one type of the secondary LED is provided; the power of the secondary LED is less than the power of the main LED, the secondary LEDs arranged between the main LEDs are evenly arranged along the LED light bar, and each main LED and each secondary LED are respectively provided with an independent power supply. The backlight saves energy, has high power supply utilization rate, and does not have colour bleaching, and a module can form dynamic response.

Description

technical field [0001] The invention relates to an LED backlight source, in particular to a hybrid LED backlight source, which is particularly suitable for providing a light source for the backlight. Background technique [0002] At present, most LED backlight strips use the same type of LEDs in a regular and continuous arrangement to provide light sources for the backlight. [0003] The Chinese patent authorization announcement number is CN201318595Y, and the utility model patent whose authorization announcement date is September 30, 2009 discloses an LED backlight source for an electric measuring instrument of a railway locomotive, including a backlight board and two rows or rows arranged on the backlight board. More than two rows of LED light-emitting tubes connected to the power supply, each row includes at least two or more LED light-emitting tubes, the LED light-emitting tubes between each row are connected in series, and the LED light-emitting tubes between rows conn...
