Example Embodiment

[0017] Example one

[0018] figure 2 It is a schematic structural diagram of an OLED driving power supply provided by Embodiment 1 of the present invention. The OLED driving power supply provided by the embodiment of the present invention may be suitable for OLED driving scenarios of electronic devices such as televisions, monitors, audio-visuals, and rear-projection plasma displays that use OLED as a display solution.

[0019] See figure 2 , The driving power provided by the embodiment of the present invention includes: a main power board 10, a main board 20, and an on-screen power board 30;

[0020] The main power board 10 is electrically connected to the main board 20 and the on-screen power board 30; the main power board 10 is used to output the first electrical signal and the second electrical signal to the on-screen power board 30 according to the first enable signal sent by the main board 20 Signal; The on-screen power supply board 30 is used to sequentially output the VDD ...

Example Embodiment

[0046] Example two

[0047] An embodiment of the present invention also provides an electronic product, which includes any of the OLED driving power supplies and an OLED screen provided in the embodiments of the present invention, wherein the on-screen power supply board in the OLED driving power supply is arranged on the OLED screen.

[0048] Exemplary, Figure 5 It is a schematic structural diagram of an electronic product provided in the second embodiment of the present invention. See Figure 5 , The electronic product is an OLED TV, in which the main power board and main board (not shown in the figure) in the OLED driving power supply are integrated in the set-top box 501, and the on-screen power supply board 502 in the OLED driving power supply is arranged on the OLED screen 503. Figure 5 In the OLED driving power supply, the on-screen power supply board 502 is arranged on the lower edge of the OLED screen 503, and has a thin and slender shape without increasing the thickne...

Abstract

The invention discloses an OLED driving power supply and an electronic product. The driving power supply comprises a main power supply board, a mainboard and an on-screen power supply board. Wherein the main power supply board is electrically connected with the mainboard and the on-screen power supply board. The main power supply board is used for outputting a first electric signal and a second electric signal to the on-screen power supply board according to the first enable signal sent by the mainboard; and the on-screen power panel is used for sequentially outputting a VDD electric signal and an EVDD electric signal according to the first electric signal and the second electric signal so as to lighten the OLED screen. A traditional power panel framework is changed into a split main powerpanel and on-screen power panel framework, so that the driving power supply is lighter and thinner on the basis of meeting strict time sequence control, and the lightening and thinning of the shape of an electronic product are facilitated.

Description

technical field [0001] Embodiments of the present invention relate to electronic circuit technology, and in particular to an OLED driving power supply and electronic products. Background technique [0002] OLED (organic light emitting diode) is superior to traditional LCD and LED in terms of image quality, response speed, thickness and viewing angle because of its advantages of self-luminescence, no need for backlight, no need for color filters and liquid crystals. , so it has been widely used in recent years. With the gradual maturity of OLED technology, TVs using OLED as a display solution will gradually replace traditional LCD and LED TVs. Compared with traditional LCD and LED TVs, OLED TVs not only have a qualitative leap in image quality, but also have a thinner , flexibility and other characteristics. Combining these features, future OLED TVs aim to be thinner and lighter. [0003] specific, figure 1 It is a structural schematic diagram of the existing OLED driving...
