Fixed graphic organic light emitting diode display with uniform high-brightness display effect

Abstract

The invention relates to a fixed graphic organic light emitting diode display with a uniform high-brightness display effect. The display comprises a driving control module, a plurality of voltage current control modules and an organic light emitting diode display module, wherein the voltage current control modules are connected with the driving control module; the organic light emitting diode display module comprises a plurality of light emitting diode elements; a plurality of light emitting diodes comprise a plurality of overlook appearances of different sizes; the overlook appearances at least comprise a cambered shape; each voltage current control module adjusts direct current power output to each light emitting diode according to overlook appearance area of each light emitting diode; and thus, the display is endowed with various technical effects of high brightness, high uniformity, long service life, high resolution and the like.

Description

technical field [0001] The invention relates to an organic light-emitting diode display, in particular to an organic light-emitting diode display with uniform and high-brightness display effect and fixed graphic display. Background technique [0002] Compared with other flat panel display (Flat Panel Display) technologies, Organic Light Emitting Diode Display (OLED Display) has good advantages in lightness, thinness, brightness, etc. To have a role to play. For example, organic light-emitting diode displays have a self-illuminating effect, which greatly reduces the structure of the display and the power consumption required. Therefore, it not only has the effect of being thin and light, but also has high brightness and high brightness compared to other flat-panel displays (such as liquid crystal displays, etc.). Low power consumption and other advantages make it a rising star in the future display field. [0003] Although the OLED display (Organic Light Emitting Diode Disp...

Problems solved by technology

[0004] (1) if Figure 5 As shown, the display content of the OLED driven and displayed in the form of a dot matrix is ​​composed of pixels 99 arranged in a dot matrix, and its display quality is not good, and it cannot display smooth and curved graphics.

[0005] (2) In order to obtain a higher resolution of the OLED display driven by a dot array, the display block must have denser and more display pixels (pixels), and more display pixels must be used to increase the display brightness. Increase the driving voltage, because the display in the form of dot array is driven by an AC square wave, higher resolution and brightness requirements will make the instantaneous voltage or current of the AC square wave very high, often breakdown and damage OLED display pixel components, or seriously shorten the service life

[0006] (3) The average current and voltage provided by the current AC square wave driving method are insufficient, so that the brightness of OLED displays is generally poor

[0007] (4) Due to the complex structure of the internal pixels of OLEDs driven by dot arrays, other switching elements are needed to control the OLEDs of the pixels, which will not only reduce the aperture ratio and greatly reduce the brightness, but also lead to poor yield due to the complex structure.

[0008] It can be seen that the above-mentioned existing organic light-emitting diode display obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
