Abstract

An icon organic light emitting diode (OLED) display with high uniformity and increased brightness has a driving module, an OLED display module and multiple power control modules. The driving module is connected to the power control modules. The power control modules generate multiple direct current (DC) powers. The OLED display module has multiple OLED units having multiple non-identical shapes and sizes. Each OLED unit is driven by one DC power based on the shape and size of the OLED unit. The OLED units with different sizes and shapes are driven respectively by proper DC powers, thus increased brightness and high uniformity of the OLED display is achieved.

Claims

1. An icon organic light emitting diode (OLED) display with high uniformity and increased brightness having a front and comprising:

a driving module receiving a display signal and transforming the display signal to a driving signal;

an OLED display module comprising

a substrate having an edge and an inner surface;

multiple OLED units being mounted on the inner surface of the substrate and comprising multiple different shapes and sizes, at least one of the shapes and sizes comprising a curved edge and being activated respectively by multiple direct current (DC) powers to emit visible light,; and

a top cover having an inner surface, being mounted on the substrate with a sealing unit being mounted on the edge of the substrate to seal the OLED units between the substrate and the top cover; and

multiple power control modules, each power control module being connected to the driving module, receiving a driving signal from the driving module and generating DC power based on the driving signal, and each power control module being connected to the at least one OLED unit and providing DC power to the connected OLED.

2. The icon OLED display as claimed in claim 1, wherein each OLED unit is a transparent conductive oxide electrode, a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer and a cathode, where the hole injection layer, a hole transport layer, an emitting layer, an electron transport layer are organic materials and the cathode is aluminum.

3. The icon OLED display as claimed in claim 1, wherein the top cover comprises a recess formed on the inner surface.

4. The icon OLED as claimed in claim 1, wherein DC power to the OLED unit is based on the size and the area of the OLED unit.

5. The icon OLED display as claimed in claim 2, wherein the hole injection layer has a thickness of between 500 A to 5000 A.

6. The icon OLED display as claimed in claim 2, wherein the top cover comprises a recess formed in the inner surface.

7. The icon OLED display as claimed in claim 3, wherein the recess has a moisture absorbent mounted in the recess.

8. The icon OLED display as claimed in claim 6, wherein a moisture absorbent is mounted in the recess.

9. The icon OLED display as claimed in claim 7, wherein the DC power to the OLED unit is based on the size and the area of the OLED unit.

10. The icon OLED display as claimed in claim 9, wherein the curved edge is part of an Arabic numeral, a character, a line or a figure.
