Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, 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.

Referring to fig. 1, an embodiment of the present invention provides a display screen for a car audio, including: VA type LCD display screen 1, wherein, the size of display screen 1 is 6.9 cun, the utility model discloses so adopted 6.9 cun as the size of display screen, because present LCD display screen generally all is small-size, it is less to show visual window, whole effect is lacked to some extent, and generally all be used for on the MP3 player, and if change into great TFT screen, thereby will improve manufacturing cost and lead to the price/performance ratio of complete machine not high, consequently, the utility model provides a section can be applicable to the display screen of multiple players such as MP3, MP4 or MP5 and android large screen machine to the preferred length with the display screen sets up to 154MM, and the width is 92MM, and the demonstration of this size window can be great, and the display effect is more excellent.

As shown in fig. 2, the LCD display screen 1 of the embodiment of the present invention does not adopt the way of PIN jack adopted by the conventional LCD screen, and the output flat cable 11 of the LCD display screen in the embodiment adopts the FPC flexible flat cable and is the flexible flat cable with 40PIN interface, so that the installation of the display screen is more convenient, and the production efficiency can be further improved; in addition, the currently commonly used 6.9-inch display screen is generally a TFT screen and is commonly used on a mobile phone, but an interface adopted by the mobile phone screen is an MIPI interface, so that the manufacturing process is more complex and the manufacturing cost is higher, while the 6.9-inch LCD display screen of the embodiment can be applied to various types of vehicle-mounted audio players, the VA process is lower in production cost and wider in application range.

The embodiment of the utility model provides a LCD display screen 1 can be divided into two parts from the display content about, wherein the first half 12 of display screen can carry out dynamic spectrum display, and the latter half 13 mainly used of display screen shows broadcast content and broadcast status etc. and can also realize the show of functions such as perpetual calendar, and the realization of these functions is realized through setting up special truth table and combining MCU to LCD display screen 1, wherein, specific truth table content is as shown in FIG. 3:

the LCD display screen 1 in this embodiment is provided with 8 COM common terminals and 32 SEG scanning terminals, where the first 32PIN interfaces of the FPC flex cable are SEG, and the last 8 PIN interfaces are COM, and when a sufficient ac voltage is applied between a certain COM and a certain SEG, the corresponding segments will be lit, that is, different LCD display segments are lit through the combination of COM and SEG, thereby forming characters or graphics.

The LCD display panel 1 of the present embodiment is designed to use 256 total points of 8 COM and 32 SEG for displaying, wherein the display panel can be further divided into an upper portion and a lower portion from the content display, the upper portion 12 uses full-dot type to display the dynamic spectrum, and the lower portion 13 preferably uses 8 arranged in 12 m-shaped to display the content and the status.

In order to better embody the utility model discloses LCD display screen compares the display effect of conventional LCD display screen better, below combine the display effect schematic diagram of the conventional LCD display screen that fig. 4 and 5 show and the truth table that corresponds to explain the difference of the LCD display screen of this embodiment and conventional LCD display screen:

it can be clearly seen from fig. 4 and 5 that, because the conventional LCD display screen is small in size, the content displayed by the conventional LCD display screen is much less than that of the LCD display screen of this embodiment, and the conventional LCD display screen is generally a 13-pin jack, in which the first 5 pins are COM, and the last 8 pins are SEG, that is, the screen display of the display screen is realized through the truth table formed by 5 COM and 8 SEG, while the LCD display screen of this embodiment is displayed through the truth table formed by 8 COM and 32 SEG, that is, the present invention is more complex in display logic, the displayed content display is also more diverse and flexible, and it is obvious that the LCD display screen of this embodiment is better than the conventional LCD display screen in terms of display content and display effect, and various functions such as dynamic spectrum display and perpetual calendar of the display screen can be easily realized by this arrangement mode of this embodiment, and the present invention is more comfortable for the user to use than the conventional LCD display screen.

To sum up, the embodiment of the utility model provides a display screen for on-vehicle stereo set, including VA type LCD display screen, the size of display screen is 6.9 cun, the output winding displacement of display screen is the FPC soft winding displacement of 40PIN interfaces, the display screen has 8 COM public ends and 32 SEG scanning ends. Through the utility model provides a 6.9 very little LCD display screen can solve the current on-vehicle stereo set LCD screen size undersize display effect not good and the not high problem of the preparation technology complexity price ratio of TFT screen, the utility model discloses an LCD display screen can be applicable to polytype on-vehicle stereo set, has improved the display effect of display screen, has promoted user's use impression, and this is not yet to be applied to on-vehicle stereo set's automobile sound industry with the LCD display screen that the display screen design is 6.9 very little VA process design at present, also is very meaningful.
