Problems solved by technology

[0005] However, the load state of the display panel 80 will change with the image data 20. For example, when the image data 20 switches from image data with low gray scale values ​​(such as dark data) to high gray scale value When there is image data (such as light-color data), or switching from image data with a high grayscale value to image data with a low grayscale value, the load state of the display panel 80 changes sharply, so the output power of the power supply 90 A significant ripple effect will be generated, thereby affecting the operational stability of the display 100
What's more, the fluctuation effect caused when the image data 20 is switched from the image data with low grayscale value to the image data with high grayscale value is likely to cause arcing phenomenon on the display panel 80, resulting in Display panel 80 burned

Embodiment Construction

[0025] Please refer to figure 2 , figure 2 It is a schematic diagram of the power output generated by the display 200 of the present invention. The display 200 includes an adjustable power supply 110, a driving circuit 160, a timing control unit 140, and a display panel 80. The driving circuit 160 is electrically coupled to the display panel 80 for driving the display panel 80. The display panel 80 includes a plurality of pixels 82, and the display panel 80 may be a self-luminous display panel, such as a field emission display panel or an organic light emitting diode display panel. The timing control unit 140 is electrically coupled to the driving circuit 160 for receiving image data 20 of a plurality of pixels 82. The image data 20 is, for example, gray-scale data of the pixels 82 for driving the pixels 82 and according to The image data 20 generates a control signal 142, and the image data 20 can be image data of a column of pixels 84 or other blocks. The adjustable pow...

Abstract

The invention discloses a display and a method for generating power output. The display comprises a power supply device including a plurality of pixels and a display panel. The method for generating power output comprises data for receiving the pixels. The data drive the pixels, and the response speed of the output power of the power supply device is adjusted based on the data and the output power is supplied to the display panel.

Description

Technical field [0001] The present invention relates to a method for generating power output by a display, and in particular to a method for adjusting the response speed of a power supply output by a power supply. Background technique [0002] Liquid Crystal Display (LCD) has the characteristics of light and thin appearance, low power consumption and low radiation pollution. It has gradually replaced the CRT monitor of traditional desktop computers and is widely used in notebook computers. , Mobile phones, TVs and other electronic products. The liquid crystal display uses the characteristics of the liquid crystal molecules to produce different polarization or refraction effects on the light under different arrangement states to control the amount of light penetration, and then display an image. [0003] Self-luminous displays such as field emission displays and Organic Light Emitting Diode (OLED) displays have the characteristics of self-luminescence. For example, organic light-em...
