Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0032] see figure 1 , is the electrical connection diagram of an existing RGB-LED, in which three RGB-LED chips are connected in parallel and have a common anode 1. In practical applications, a 5V voltage is input, and a different resistor is connected in series at each chip. The value of the voltage divider resistor plays a role in reducing the voltage.

[0033] see figure 2 , is an electrical connection diagram of an energy-saving RGB-LED package provided by the present invention. In the present invention, the anode 6 of the red chip and the cathode 2 of the red chip are separately drawn out, and the common anode 5 of the blue and green chips is used to drive the The red light chip with smaller voltage requirement is led out separat...

Abstract

The invention provides an energy-saving RGB-LED package, a package module and a display screen thereof. The energy-saving RGB-LED package comprises a substrate and a light-emitting unit arranged on the substrate; the light-emitting unit comprises a red light chip, a green light chip and a blue light chip; the positive electrode and the negative electrode of the red light chip are separately led out; and the green light chip and the blue light chip share one positive electrode or share one negative electrode. The energy-saving RGB-LED package module comprises the energy-saving RGB-LED package, and at least two light-emitting units are arranged on the energy-saving RGB-LED package. The energy-saving RGB-LED display screen includes the energy-saving RGB-LED package. The energy-saving RGB-LED package, the package module and the display screen thereof provided by the invention change the traditional chip driving mode, separate the driving circuits of the red light chip, the blue light chip and the green light chip, provide a separate power driver for the red light chip, and reduce the driving voltage, thereby greatly reducing the power consumption.

Description

technical field [0001] The invention relates to SMD LED (Surface Mounted Devices, surface mount device) packaging technology, in particular to an energy-saving RGB-LED packaging body, a packaging module and a display screen thereof. Background technique [0002] The existing small-pitch display screens mainly use 2121, 1515, 1010, 0808 and other packaged devices, all of which are 4-pin devices. One anode or cathode of the red, green, and blue chips is connected in parallel through a common anode or common cathode, and the other one The pins are brought out separately. The characteristic requirements of red, green and blue light chips are that the driving voltage of red light chips is about 2V, and the driving voltage of blue and green light chips is about 3V. Connect voltage divider resistors with different resistance values ​​in series. Although this solution is simple and easy to implement, it has two major defects: one is that the voltage dividing resistors generate a l...
