The paper describes a low-cost, versatile, widely applicable digital display system in which a high-resolution, high-intensity display unit is driven by a real-time vector scan controller. The actual online display control of this device is preceded by an offline software stimulus-frame editor, designed to create and support a library of stimulus patterns (standard frames without any timing information and without any referencing to a special display co-ordinate system). The display times can be set individually for each single frame (containing at maximum 1023 pixels) with relative ease. Display frequency is set to 1 kHz. Writing time per pixel is less than 1 microsecond. A graphic display system like the one presented in this paper can be applied to generate a variety of real-time optical stimuli, such as intensity modulation of single spots or distinct display areas, abrupt displacements of a certain pattern, continuous movement or onset and offset of steady motion of a pattern.
本文描述了一种低成本、通用且广泛适用的数字显示系统，其中高分辨率、高强度显示单元由实时矢量扫描控制器驱动。该设备的实际在线显示控制之前有一个离线软件刺激帧编辑器，其设计用于创建和支持刺激模式库（没有任何定时信息且不涉及特殊显示坐标系的标准帧）。可以相对轻松地为每个单帧（最多包含1023个像素）单独设置显示时间。显示频率设置为1kHz。每个像素的写入时间小于1微秒。像本文中介绍的这种图形显示系统可用于生成各种实时光学刺激，例如单个点或不同显示区域的强度调制、特定图案的突然位移、图案的连续移动或稳定运动的开始和结束。
