Abstract
Description
Technical Field
[0001] The present invention relates to a pixel array, and in particular to a pixel array related to light emitting diodes. Background Art
[0002] In addition to the basic liquid crystal display (LCD), advanced display technologies include active-matrix organic light-emitting diode (AMOLED), sub-millimeter light-emitting diode (Mini LED), micro-light-emitting diode (Micro LED), etc. Currently, the main ones in our lives are active-matrix organic light-emitting diode and sub-millimeter light-emitting diode, while micro-light-emitting diode is still under development. However, micro-light-emitting diode has the characteristics of high contrast, low power consumption and long service life, and its potential as an environmentally friendly next-generation display has attracted much attention.
[0003] Considering the cost and power consumption, micro-LEDs will use the Pentile pixel arrangement. However, the actual resolution of the Pentile pixel arrangement can only reach two-thirds of the nominal resolution. However, at a lower resolution, the graininess of the picture will be very heavy, resulting in the problem of grid points in the visual effect. Summary of the invention
[0004] The invention provides a pixel array, which can reduce the power consumption of light emitting diodes and suppress the problem of grid points in visual effects.
[0005] The pixel array of the present invention includes a plurality of pixel driving circuits and a plurality of light emitting diodes. The pixel driving circuits are individually coupled to one of the plurality of scanning lines to receive scanning signals, coupled to one of the plurality of luminous lines to receive luminous signals, and coupled to one of the plurality of data lines to receive pixel data. The light emitting diodes are arranged in an array, wherein an anode of a first light emitting diode of the light emitting diodes is coupled to one of the pixel driving circuits, a cathode of the first light emitting diode is coupled to an anode of a second light emitting diode of the same color as the first light emitting diode, and a cathode of the second light emitting diode receives a system low voltage.
[0006] Based on the above, in the pixel array of the embodiment of the present invention, the LEDs are driven according to color groups, but the LEDs that light up at the same time are in different positions. Therefore, the pixel array can reduce the power consumption of the LEDs and suppress the problem of grid points in visual effects.
