Embodiment 1

[0018] figure 2 It is a schematic structural diagram of an OLED driving power supply provided in Embodiment 1 of the present invention. The OLED driving power provided by the embodiments of the present invention can be applied to OLED driving scenarios of electronic equipment such as TVs, monitors, audio-visual education, and rear projection plasma displays that use OLEDs as display solutions.

[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] Wherein, the main power board 10 is electrically connected with the main board 20 and the on-screen power board 30; Signals; the on-screen power board 30 is used to sequentially output the VDD electrical signal and the EVDD electrical signal according to the first electrical signal and the second electrical signal, so as to light the OLED screen.

[0021] The drive power provided by the embodiment of ...

Embodiment 2

[0047] The embodiment of the present invention also provides an electronic product, the electronic product includes any OLED driving power supply provided in the embodiments of the present invention and an OLED screen, 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 by Embodiment 2 of the present invention. see Figure 5 , the electronic product is an OLED TV, wherein the main power board and main board (not shown) in the OLED driving power are integrated in the set-top box 501, and the on-screen power board 502 in the OLED driving power is arranged on the OLED screen 503. Figure 5 Among them, the on-screen power supply board 502 in the OLED driving power supply is set on the lower edge of the OLED screen 503, which is thin and elongated, does not increase the thickness of the OLED screen, and maintains the thinness of...

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...
