摘要： By varying corona producing element height/projection, a more uniform charge potential is achieved. Elements, such as pins or teeth, are shorter at the edges of an element array and grow longer as one moves toward the center of the array. Such variation in height/projection overcomes shielding from adjacent teeth, as well as other effects, to yield the more uniform charging potential.

摘要： A OLED-based edge emitter mitigates the problem of unacceptably large losses by physically separating the OLED from the waveguide using an optical cladding layer. An additional advantage over conventional surface emitting OLEDs used in image bars is the pixel aspect ratio of the edge emitter. The pixel-aspect ratio is narrow in the process direction forming a rectangle. This rectangular shape allows movement to make an effective square. Therefore, emission modulation can be performed at a high duty-cycle because the edge is much shorter in the process direction than in the lateral, i.e., fast scan direction. As a result, the duty cycle of the light source can be higher, i.e., the light source is on for a longer time, without smearing an irradiated spot into locations corresponding to adjacent pixels.
摘要翻译：基于OLED的边缘发射器通过使用光学包层物理分离OLED与波导来缓解不可接受的大损耗的问题。与图像条中使用的常规表面发射OLED相比的另外的优点是边缘发射器的像素长宽比。像素长宽比在形成矩形的处理方向上较窄。这种矩形允许移动来形成一个有效的平方。因此，发光调制可以在高占空比下进行，因为边沿在横向，即快速扫描方向上要比处理方向短得多。结果，光源的占空比可以更高，即光源打开更长的时间，而不会将照射的点污染到对应于相邻像素的位置。

摘要： An integrating xerographic light emitter array includes circuitry for operating an active matrix array of organic light emitting diodes (OLEDs). The light emitter array stages rows of emitters in the slow scan direction and moves the object image and synchronization with the photoreceptor. Grey scale resolution, increased emitter lifetime and the ability to operate at lower light levels are achieved in proportion to the number of stages. The entire printbar can be rewritten during each line time of the photoreceptor, which allows the exposure on any pixel on the photoreceptor to be varied in a number of grey levels from zero to the number of stages. Bringing a grey level signal to the photoreceptor allows improved continuous tone image quality and line placement. Additional grey resolution is obtained by analog driving of individual pixels. This technique is applicable to a variety of emitters or light valves, but is particularly suited to inexpensive OLEDs. Greater exposure uniformity results because each photoreceptor spot receives light from an ensemble of emitters. The integrating xerographic light emitter array can also use static digital memory which is particularly suited to random access display writing.
摘要翻译：集成静电照相发光器阵列包括用于操作有机发光二极管（OLED）的有源矩阵阵列的电路。光发射器阵列在慢扫描方向上排列发射器的行并移动对象图像并与感光体同步。实现灰阶分辨率，增加的发射器寿命以及在较低的光照水平下操作的能力与阶段的数量成比例地实现。可以在感光体的每个行时间期间重写整个打印条，这允许在感光体上的任何像素上的曝光在从零到数量级的多个灰度级中变化。将灰度信号带到感光体可以改善连续色调图像质量和线放置。通过单个像素的模拟驱动获得额外的灰度分辨率。这种技术适用于各种发射器或光阀，但是特别适用于廉价的OLED。由于每个感光体点都接收到来自发射体的集合的光，因此产生更大的曝光均匀性。积分静电照相发光阵列还可以使用特别适合于随机存取显示写入的静态数字存储器。

摘要： A method for detecting charge defect spots (CDSs) on a chargeable surface is provided, including charging the chargeable surface to receive and hold a first voltage charge, spacing a surface of a scanner probe a distance from the chargeable surface, the scanner probe having a diameter, and biasing the scanner probe to a second voltage charge within a predetermined voltage threshold of the first voltage charge, wherein a parallel plate capacitor is established with the chargeable surface and a dielectric substance between the scanner probe and the chargeable surface. The method further includes reading with the scanner probe potentials associated with charges induced from the applied charges and any CDSs on the chargeable surface, including sensing the potentials and generating a signal corresponding to the sensing, applying a reference charge to the chargeable surface, and determining the potential of a CDS on the chargeable surface based on the scanner probe readings and at least one of the applied charges, which includes correcting for non-uniform charge distribution caused by a point-like nature of the CDS on the chargeable surface.
