Embodiment Construction

[0045] In order to have a further understanding and understanding of the structural features and the realized effects of the present invention, a detailed description of the preferred embodiments and accompanying drawings is as follows:

[0046] First, see image 3 , Figure 3A and Figure 3B , which are respectively a structural cross-sectional view, a top view, and a schematic circuit diagram of a preferred embodiment of the light-emitting diode chip of the present invention; 33 has a PN interface 335 that can produce a light source effect, just like a commonly used single light-emitting diode, the width of the substrate 31 can be W, and the light-emitting layer 33 will be chiseled with at least one isolation channel 37 . For example, in the two isolation channels 37 in this embodiment, each isolation channel 37 can extend to the surface of the substrate 31 or go deep into the substrate 31 to expose part of the substrate 31 to divide the light emitting layer 33 into a plur...

Abstract

A luminous layer is formed on substrate to make a light-emitting diode. The luminous layer is etched to form an isolation channel that extends to the surface of substrate, and is partitioned into multi luminous units. Each luminous unit comprises a first electrode and a second electrode. Wherein, the second electrode of a luminous unit is connected to the first electrode of an adjacent luminous unit, by this way all luminous units are connected one by one. The invention can improve the luminous efficiency and reduces the volume of light emitting diode.

Description

technical field [0001] The invention relates to a diode, in particular to a light emitting diode chip. Background technique [0002] Light-Emitting Diode (LED; Light-Emitting Diode) is widely used in indicator lights due to its characteristics and advantages of long life, small size, low calorific value, low power consumption, fast response, no radiation and monochromatic light emission. , Advertising billboards, traffic lights, car lights, display panels, communication tools, consumer electronics and other products. [0003] Common light-emitting diodes, such as planar light-emitting diodes, such as figure 1 As shown, the light-emitting diode 10 is mainly formed with a light-emitting layer 13 on the surface of a substrate 11 with a width of W. The light-emitting layer 13 has a PN interface 135 that can produce a light source effect. The first electrode 151 and a second electrode 153 . When a supply voltage V is connected between the first electrode 151 and the second ele...
