Abstract
The utility model discloses a fixed resolution low-cost Type-C interface display, which comprises a Type-C interface module, a Switch chip module, a PD chip and an E-DP screen, wherein the Type-C interface module is used for transmitting Type-C signals; the Switch chip module is connected with the Type-C interface module and is used for outputting a Type-C signal transmitted by the Type-C interface module as a DP signal; the PD chip is connected with the Switch chip module; the E-DP screen is used for receiving the DP signal output by the Switch chip module so as to output a signal with single resolution. This application is direct to go to drive E-DP screen with the DP signal of Type-C interface to save a Sca l er chip, greatly reduced product cost.
Description
Technical Field
The utility model relates to a display technical field especially relates to a fixed resolution ratio low-cost Type-C interface display.
Background
As shown in fig. 1, a block diagram of a conventional portable display is schematically shown, and a main chip of the display is used for displaying an e-DP screen, which supports multiple resolution inputs, and the main chip processes the screen with a fixed resolution. In a specific application scene, only single-resolution input and single-resolution output need to be considered, and if a display main chip dot screen is still used, the cost is too high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a fixed resolution ratio low-cost Type-C interface display aims at solving above-mentioned problem.
The Type-C interface display with the fixed resolution and the low cost comprises a Type-C interface module, a Switch chip module, a PD chip and an E-DP screen, wherein the Type-C interface module is used for transmitting Type-C signals; the Switch chip module is connected with the Type-C interface module and is used for outputting a Type-C signal transmitted by the Type-C interface module as a DP signal; the PD chip is connected with the Switch chip module; the E-DP screen is used for receiving the DP signal output by the Switch chip module so as to output a signal with single resolution.
The utility model discloses an among the low-cost Type-C interface display of fixed resolution ratio, the E-DP screen is the LED display screen.
The technical scheme provided by the embodiment of the application can have the following beneficial effects:
the application provides a fixed resolution ratio low-cost Type-C interface display can directly drive the E-DP screen with the DP signal of Type-C interface to save a Scaler chip, thereby greatly reduced product cost.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without any creative effort.
FIG. 1 is a block diagram showing a conventional portable display;
fig. 2 is a block diagram schematically illustrating a display according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in the specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
Referring to fig. 2, the utility model discloses a fixed resolution ratio low-cost Type-C interface display, it includes Type-C interface module, Switch chip module, PD chip and E-DP screen. The Type-C interface module is used for transmitting Type-C signals, the Switch chip module is connected with the Type-C interface module and used for outputting the Type-C signals transmitted by the Type-C interface module into DP signals. And the PD chip is connected with the Switch chip module. The E-DP screen is used for receiving the DP signal output by the Switch chip module so as to output a signal with single resolution.
The original DP protocol signal can be transmitted in the Type-C interface, and the E-DP protocol and the DP protocol of the E-DP screen are the same in video signal transmission, except that the DP contains an audio signal, and the E-DP does not contain the audio signal. Therefore, the DP signal of the Type-C interface can be directly used for driving the E-DP screen, so that a Scaler chip is omitted, and the product cost is greatly reduced. This application Type-C interface can directly transmit the DP signal, directly drives the screen after processing through positive and negative the inserting, and the EDID of screen is directly acquireed to the information source, exports the signal of single resolution. The fixed resolution low-cost Type-C interface display reduces product IC cost, facilitate promotion in the range.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
