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 arranged 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 thinne...

Abstract

The invention discloses an OLED driving power supply and an electronic product, wherein the driving power supply comprises: a main power board, a main board and an on-screen power board; wherein, the main power board is electrically connected to the main board and the on-screen power board ; The main power board is used to output the first electrical signal and the second electrical signal to the on-screen power board according to the first enabling signal sent by the main board; The first electrical signal and the second electrical signal output a VDD electrical signal and an EVDD electrical signal in sequence to light up the OLED screen. By changing the traditional power board architecture to a split main power board and on-screen power board architecture, the driving power supply can be thinner and lighter on the basis of meeting strict timing control, which is conducive to the realization of thinner and lighter electronic products.

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...
