    • A virtual ground NROM array has a matrix of NROM cells in which during an erase operation the non-erasing side of NROM cells are connected to a common node for enhancing the erase uniformity of the NROM array. If an operation requests erasing on the left side of NROM cells, a positive voltage is supplied from an internal power supply to the left side for each of the NROM cells, and the right side for each of the NROM cells is discharged to a common node. If an operation requests erasing the right side of NROM cells, a positive voltage is supplied from the internal power supply to the right side for each of the NROM cells, and the right side for each of the NROM cells is connected to the common node. The voltage level of the common mode is selected to be sufficiently high in order to prevent from punch through while at the same time sufficiently low to maintain the lateral electric field for erase operation to function optimally. In an alternative embodiment, non-erasing sides of NROM cells in the NROM array are connected to a current source during an erase operation for enhancing the erase uniformity of the NROM array. If an operation requests erasing the left side of NROM cells, a positive voltage is supplied from an internal power supply to the left side for each of the NROM cells, and the right side for each of the NROM cells is discharged to a current source. If an operation requests erasing the right side of NROM cells, a positive voltage is supplied from the internal power supply to the right side for each of the NROM cells, and the right side for each of the NROM cells is connected to the current source.
    • 虚拟接地NROM阵列具有NROM单元的矩阵,其中在擦除操作期间,NROM单元的非擦除侧连接到公共节点,以增强NROM阵列的擦除均匀性。 如果操作请求在NROM单元的左侧擦除,则对于NROM单元中的每一个,从内部电源向左侧提供正电压,并且将NROM单元中的每一个的右侧放电到公共节点 。 如果操作请求擦除NROM单元的右侧,则对于每个NROM单元,从内部电源向右侧提供正电压,并且每个NROM单元的右侧连接到公共节点。 选择共模的电压足够高以防止穿通,同时足够低以保持用于擦除操作的横向电场最佳地起作用。 在替代实施例中,在擦除操作期间,NROM阵列中的NROM单元的不擦除侧连接到电流源,以增强NROM阵列的擦除均匀性。 如果操作请求擦除NROM单元的左侧,则从NROM单元的每一个的内部电源向左侧提供正电压,并且将NROM单元中的每一个的右侧放电到电流源。 如果操作请求擦除NROM单元的右侧,则从NROM单元的每一个向内部电源向右侧提供正电压,并且每个NROM单元的右侧连接到电流源。

    • An exemplary backlight module (20) includes a light guide plate (21), a plurality of point light sources (22), and a transparent light diffusing element (23). The light guide plate includes a light incident surface (211). The point light sources are positioned adjacent to the light incident surface. The light diffusing element is positioned between the point light sources and has a light incident surface. The light diffusing element includes a plurality of recesses (231) which face the light incident surface and correspond to the point light sources. The light diffusing element can diffuse light from the point light sources, therefore increasing emitting angles of the point light sources. The recesses of the light diffusing element can make light from the point light sources more uniform.
    • 示例性背光模块(20)包括导光板(21),多个点光源(22)和透明光漫射元件(23)。 导光板包括光入射面(211)。 点光源位于光入射表面附近。 光漫射元件位于点光源之间并具有光入射面。 光漫射元件包括面对光入射面并对应于点光源的多个凹部(231)。 光漫射元件可以漫射来自点光源的光,从而增加点光源的发射角度。 光漫射元件的凹部可以使来自点光源的光更均匀。

    • An assembled flash display module comprising a shell body, a flash lamp set and a control unit is disclosed. The shell body is disposed with an accommodation space therein. The flash lamp set is arranged in said accommodation space and consists of at least two flash lamps that emit different colors of light. The flash lamps and the control unit are electrically connected. The control unit further comprises a trigger circuit and a regulating circuit, through which, the on time of trigger electrode of flash lamps is controlled to regulate the flashing intensity of the flash lamps. The present invention offers multiple color flashes and more luminous display in comparison with other light-emitting display units, and hence is more useful in practical applications.
    • 公开了一种组装的闪光显示模块,其包括壳体,闪光灯组和控制单元。 壳体在其中设置有容纳空间。 闪光灯组布置在所述容纳空间中并且由至少两个发射不同颜色的光的闪光灯组成。 闪光灯和控制单元电连接。 控制单元还包括触发电路和调节电路,控制闪光灯的触发电极的接通时间以调节闪光灯的闪光强度。 与其他发光显示单元相比,本发明提供多种颜色闪烁和更多的发光显示,因此在实际应用中更有用。
