Brief description of the drawings

Fig. 1 is a kind of schematic diagram of OLED points screen device of the utility model.

Embodiment

The utility model is described in further detail for explanation and embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1, a kind of OLED points screen device, including FPGA module 102（Field-Programmable Gate Array, i.e. field programmable gate array）, at least two-way MIPI points screen assembly（That is mobile industry processor interface, Mobile Industry Processor Interface）With OLED screen 104（Organic Light-Emitting Diode, UIV OLED, also known as Organic Electricity laser display, organic luminous semiconductor）, the output terminal of the FPGA module 102 respectively with every road institute The connection of MIPI points screen assembly is stated, MIPI points screen assembly described in per road is connected with the OLED screen 104 respectively, the MIPI points screen group Part includes rgb interface, bridging chip 103 and MIPI interfaces, wherein, the output terminal of the FPGA module 102 is respectively by described Rgb interface is connected with the input terminal of the bridging chip 103, and the output terminal of the bridging chip 103 passes through the MIPI interfaces It is connected, is merged by multigroup MIPI signals to drive OLED screen 104, the FPGA module 102 is realized with the OLED screen 104 The synchronous transmission of at least 2 groups RGB datas.

As shown in Figure 1, the input terminal of the FPGA module 102 is connected with computer 101（PC）.

As shown in Figure 1, the input terminal of the FPGA module 102 is connected by USB interface with the computer 101.

PC ends will carry out image procossing, and the view data of QHD is divided into 2 groups, is sent to 2 groups through FPGA module 102 respectively On rgb interface, rgb signal is changed into MIPI signals by the bridging chip 103 at the same time, and then 2 groups of MIPI signals are synchronously sent To OLED screen 104, MIPI signals merge extension MIPI communication bandwidths to drive high resolution OLED screen curtain, including at software image Reason and hardware plan realization, a kind of OLED points screen device provided by the utility model, it would be preferable to support the resolution MIPI of higher connects The OLED screen of mouth.

As shown in Figure 1, a kind of course of work of OLED points screen device comprises the following steps：

S1, be divided at least two groups of rgb signals by view data by FPGA module 102 and synchronously send to bridging chip 103；

S2, be converted into MIPI signals through bridging chip 103 by each group rgb signal respectively and synchronously send to OLED screen 104；

S3, merge extension MIPI communication bandwidths to drive the OLED screen 104 of high resolution by each group MIPI signals respectively.

A kind of OLED points screen device provided by the utility model, multigroup MIPI, which synchronously sends signal, can support QHD OLED point screens above, pass through MIPI（Mobile Industry Processor Interface）The merging of signal goes to drive OLED screen 104, realizes the screen test of the OLED screen 104 of driving high resolution.

Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded To belong to the scope of protection of the utility model.
