求如下这段文字的英文翻译，毕业论文急用啊。哪位好心的朋友帮忙翻译一下，谢谢了!

Question

LED电子显示屏是随着计算机及相关的微电子光电子技术的迅猛发展而形成的一种新型信息显示媒体。它利用发光二极管构成的点阵模块或像素单元组成可变面积的显示屏幕，以可靠性高使用寿命长，环境适应能力强，性能价格比高，使用成本低等特点，在短短的十来年中，迅速成长位平板显示的主流产品，在信息显示领域得到了广泛的应用。
本设计采用AT89C52单片机作控制器，12MHZ晶振，8×8点阵共阳LED显示器，其中，P0作为字符数据输出口，P2为字符显示扫描输出口， P1.0~P1.2口分别接开关K1、K2、K3，通过按下按键转换3种显示效果：逐字显示上移滚动显示，左移滚动显示，另外改变列线中的电阻大小可改变显示字符的亮度。

Answer 1

LED electronic display, with the computer and related microelectronics the rapid development of photonics technology and the formation of a new information display media. It constitutes the use of light-emitting diode pixel dot matrix module or modules variable area of the display screen, high reliability and long life, a strong ability to adapt to the environment, high cost performance, the use of low cost, in a short period Of 10 years, the rapid growth in the mainstream of flat panel display products in the field of information display has been widely used.
The design of a microcontroller for AT89C52 controller, 12 MHZ crystal, 8 × 8-dot-matrix of LED displays, which, P0 as a character data output, P2 characters appear to scan output, P1.0 ~ P1.2 mouth Were to switch K1, K2, K3, press the button through the conversion of three effect: verbatim displayed on a rolling shift, the left rolling, other changes are in the line of resistance can change the size of the characters display brightness.
