Abstract

A luminous device with dependent votlage / resistor layer is composed of a luminous unit with a first and second surfaces, the first electrode on the first surface, the secone electrode on the second surface, and a dependent voltage / resistor layer connected to both the first electrode and the second electrode for antistatic purpose.

Description

technical field [0001] The invention relates to a light-emitting element, in particular to a light-emitting element with a piezoresistive layer. Background technique [0002] Light emitting devices are widely used, for example, in optical display devices, laser diodes, traffic signs, data storage devices, communication devices, lighting devices, and medical devices. In this field, one of the important tasks for technicians at present is how to avoid damage to light-emitting elements caused by static electricity, so as to improve the pass rate of light-emitting elements. [0003] Such as figure 1 As shown, in order to avoid damage to the light-emitting element caused by static electricity in the light-emitting element of the prior art, a set of Zener diodes (Zener Diode) will be added when the light-emitting element is packaged, so that the electrostatic discharge caused by the environment can pass through the Zener diode In order to avoid damage to the light-emitting eleme...
